In short

The “No Trees, No Seas” campaign argues that ocean health depends on restoring forests and rivers upstream, using a connected “flowscape” framework rather than treating land and sea as separate systems.

Guests (backgrounds)

  • Carl Rowlandson: co-founder of Plant One, a Cornwall community interest company; former arborist/tree surgeon; focuses on native woodland restoration at scale in Cornwall.
  • Sam Manning: forest ecologist and environmental writer at the Woodland Trust; works on protecting/restoring temperate rainforests; research and translation informed by indigenous knowledge and overseas rainforest restoration models.

Key claims

  • Deforestation and degraded catchments destabilize flowscapes, harming plankton, fish nurseries, and marine food webs.
  • Forests support plankton via nutrient/iron inputs (citing the thesis “If the forest dies the sea dies”).
  • Healthy flowscapes reduce pollution surges and support “good” plankton (diatoms) over harmful blooms (red tides).
  • Cornwall’s low forest cover (about 8% cited) makes it a critical test case.

Notable examples

  • Japan’s “fish forest” legal designation (protecting ~60,000 hectares) and the yotsuki movement.
  • Pacific Northwest indigenous-linked knowledge; salmon as a nutrient bridge between ocean and woodland.
  • Cornwall restoration sites like Bodman/Kabila and the Helford catchment (“Fall and Helford flowscapes”).

0:03Sam Manning:My name is Larry Stafford and you're listening to Hell or High Water, the Finistead podcast exploring the depths of our oceans and the resilience of the human spirit.

0:15Sam Manning:Welcome back to the show. For this latest episode, we are joined by two people working at the sharp end of a conservation campaign that is changing how we understand the relationship between land and sea. Carl Rowlandson is co-founder of Plant One a Cornwall based community interest company working to restore native woodland at scale Sam Manning is from the Woodland Trust one of the UK's leading voices in woodland advocacy and conservation both are friends of the business both are surfers both are incredibly switched on and active activists you might ask why we joined by two woodland folk on what is a podcast that typically explores our relationship with water, the sea, the ocean, people and projects.

1:01Sam Manning:But that's just it. The ocean doesn't begin at the shoreline. That's one of the central ideas at the heart of today's conversation. And once you hear it, it's hard to unsee. What happens on the land, in the soil, in the roots of a tree, on a hillside, ripples outward, literally into the sea. Together, Carl and Sam, along with their equally dedicated crew are the people behind the No Trees, No Seas campaign. A breakthrough campaign making the scientific and moral case you cannot protect the ocean without protecting the forests and rivers that feed it. We talk about how this campaign came to be, the indigenous knowledge and ecological science that underpins it, the urgency for nature-based solutions in the face of our dual climate and biodiversity crises, and the concept that ties it all together, the flowscape, A newly defined framework that redraws the boundaries between land and sea as a single connected living system.

1:57Sam Manning:This is one of those conversations that shifts something. So let's get into it. Here's our latest episode of Hella High Water with Carl Rowlinson and Sam Manning. No trees, no seas. We've had a lot of back and forth over the last several years. you and myself Sam over the last year or so in relation to No Trees No Seas and the work that you're doing outside of that as well it's a beautiful conversation that I've become somewhat versed in I think it's something incredibly potent the momentum you guys have and have had over the last year alone it's incredible you've got a screening was just big screening in Falmouth again two nights ago there's been multiple screenings in Falmouth and the surrounding towns all the way to the end of July that's Regent Street Cinema yep which is a pretty special place to be taking something of this this this topic but for those listeners maybe new to this no trees no seas what is the the meaning behind that how did you guys come to cross paths and then it's just getting to the background of each of you and your individual work and then how this whole beautiful thing was born so um sam i'll start i'll start with you sam manning of sam b manning of the woodland trust and substack what's your work and what's your life in in terms of trees and seas there's many sounds in this campaign i think i'm one of four three or four yeah um but yeah so i mean my background is i'm a forest ecologist and environmental writer i've worked in conservation specifically forest conservation for about 15 years i specifically work in protecting temperate rainforests so sites like this one behind us we can reference this whenever you need as well this is it's in full bloom and the tide's coming up yeah so a lot of my work's been around you know conserving restoring those but i'm never happy and i've had this feeling that we're just not achieving the goals we need to in terms of nature recovery or haven't been in the environmental movement particularly in the uk for a long time and that's led me on this kind of search for how can we do it better fundamentally and in my work a lot of what that involves is looking abroad to other rainforest nations because the rainforest movement in the uk is very new it's only about six years old but other rainforest nations that have temperate rainforest as well they're much more developed in how they restore protect and see that so my work's been kind of trying to understand how they do their thing and what i've noticed about them through research translation work and the general journalist stuff is that they see the environment much more holistically and they especially see the ocean and forest as connected and that's what's special about these forests really is they're created by the sea or they're forged by it like the proximity to it because they're effectively there because of the rainfall and the water but they also have these really tangible connections that I've kind of been uncovering from mostly from indigenous knowledge from places like the Pacific Northwest of Canada, Vancouver Island in particular, and Japan.

4:49Sam Manning:So that's kind of how I came to the story, really trying to find knowledge that can help us restore our forests here, because we have we are one of the most deforested countries on earth. We've only got about 13.6 % forest cover in Cornwall, we're even worse for about 8%. But in places like japan they have this really prolific tree culture and they have up to 70 forest cover and they can still see these links that we've lost in between the forest solutions and i was kind of looking for a place to put this story and then that's where i met car on a windy hill

5:18Carl Rowlandson:in bodman yeah yeah rainy about 14 months ago yeah yeah um boys that's romantic no exactly saw each other across the misty moor yeah some pride and prejudice scene okay yeah it was it was a special moment but um yeah i was so i i started plant bomb about seven years ago with an aim to get some trees in the ground basically so i was a arborist been an arborist for sort of 15 years climbing trees tree surgeon and uh just was looking at a way to kind of affect positive change and started to understand the kind of the makeup of Cornwall and then the UK as this kind of forest island as a forest nation and then looking around and seeing that we'd completely stripped it of all the woodlands you know our forests are completely gone we've got two percent left of our ancient woodland the bits that we have left are kind of badly managed and started to understand well this is kind of the habitat where our native floor and fauna that's where they live this is kind of if we want biodiversity in the countryside hedgerows woodlands forest they're the best ways to do it so i started to put my knowledge as a tree surgeon into practice by looking at little bits of land to reforest and i kind of knocked on people's doors kind of begged borrowed and steeled to get some trees in the ground and then that kind of just grew into into a momentum and seven years later it's now a fully functioning reforestation non-for-profit and getting some trees in the ground so yeah starting to hopefully affect change in cornwall yeah

6:47Sam Manning:And you have done. And I think that's abundant to see just again, like the last 12 months, 18 months. I remember I think, you know, Sam saying that you as a small CIC have done the work of much bigger organisations out there as well. So it's credit to you because our first meet cute was me seeing you roam around conferences in the UK, carrying a small oak tree in your hand, bothering anybody you could to talk about these this conversation and why it was so important and what you knew to be true down in Cornwall.

7:17Carl Rowlandson:yeah yeah i was trying to represent oak trees and then i realized that when i was going to these sustainability conferences i just needed to take a tree with me yeah and it was like just i was like curing the coffee and i just turn around to the person next to me just hold my tree a second while i get some of that and then instantly i think that's how i bothered you larry it's listen it's when i first fell in love with you carl yeah but yeah exactly it was just about

7:39Sam Manning:well to have something physical right yeah using that tree to tell that story there's something we did as a business actually in the in the world of b court where we had a seat at the table um that's like an empty conference room table at the boardroom level um that would be the seat and the voice for the ocean right so like to actually have like physical or non-physical representation of the thing you were trying to protect there like you know yeah it's um so i get it and then you had the your beautiful dog willow in tow client ambassador there you go does a lot of the heavy

8:08Carl Rowlandson:lifting for sure yeah yeah but yeah and then uh well I was yeah on that more Sam was telling me about the research he'd been doing and I kind of I started running these events over the last few years called where the trees meet the seas and I was kind of like just gnawing at this idea that maybe there was kind of a connection between the forest and the ocean without actually knowing any of the research I just kind of it just intrinsically felt like there was something there and then I met Sam and he told me about the research he'd been working on for the last kind of eight years and it was it was mind-opening and it was mind-blowing but the kind of the thing that was so kind of like wow was like it just made sense it was just a penny drop moment was like it all clicked into place it was like we are a forest island in the middle of the north atlantic in this kind of temperate zone surrounded by this beautiful maritime industry and the question is is there a conversation going on between that forested habitat and our marine ecosystems and And when Sam kind of laid it out for him and told me like the mechanism behind it, it was like, of course, that absolutely makes sense.

9:10Sam Manning:Yeah. And I think that's one of the biggest, it's actually been one of the biggest things for us at Finisterre to understand around being this, you say, rainforest nation. That would be relatively new lexion for people out there. It's, I have never identified as a rainforest person or nation before. and it's now very much part of the dialogue. But you think rainforest, you think the Amazon, you might think British Columbia. You certainly, you know, the average Joe Bloggs wouldn't think the UK is a rainforest nation. I think people sometimes forget to remember we're an island nation.

9:46Carl Rowlandson:Yeah, yeah, yeah, absolutely. It's easy to kind of forget that. Especially, you know, I grew up in Manchester and you're only ever really a couple of hours away from the sea, but you can be so kind of disconnected from it sometimes.

9:56Sam Manning:70 miles, I think, is the furthest point. Is that it?

9:59Carl Rowlandson:Yeah, yeah. No, it's, yeah. To remind ourselves that we are an island nation, but we're a forest, rainforest island. But yeah, you could probably kind of talk about what makes us a rainforest, you know, what is a temporary rainforest.

10:13Sam Manning:Yeah, and then an Atlantic temporary rainforest. Yeah, I think it might just be worth picking on a couple of things. So, you know, we talked about how these forests adjacent to the, you know, where they actually physically meet the sea is really important. But we often start there in the story because actually, you know 70 miles inland forests there are still affecting the ocean and that's what i think this story is why this story is important because it's about how all trees as far inland any person is actually linked to the sea because of that at the moment people i think are yearning for connection with nature and i think what the rainforest movement does is it it's a conduit for that it allows people to reconnect with what would have been the native habitat and what our cultures would have evolved within and we're one of the few rainforest nations that have actually had that link severed because in places like Vancouver Island and Charnoom Nation they subsisted in that land in that rainforest for tens of thousands of years so they still have that link similar with in Japan with the Ainu people at last year I actually had this incredible experience where the Ashwininka and Gurani Amazonian rainforest people came to the UK as part of the COP30 process and they wanted to meet with rainforest people here and see a rainforest here and that I felt quite emotional about that actually quite taking people around rainforests from Dartmoor and Yes, safe to say they were kind of astonished at the lack of rainforest that we had and the state that they were in.

11:30Sam Manning:But it still felt like we had this identity that was shared with them, which was great. But on temperate rainforest, what they actually are. Scientifically, they are a habitat that receives over a meter and a half of rainfall a year. That's spread over about 200 days of the year. So very wet. And we know that. We know we're in one because we experience this every year. But then also they are forests that exist at the end of these long oceanic currents like the Gulf Stream. in japan it's called the kuroshi current or the black stream which i think sounds so much cooler than the gulf stream but it's that kind of life-giving stabilizing ocean upwelling that gives it the warm temperature it shouldn't really have at this latitude but also that high level of rainfall and in that sense they are directly connected to the ocean because they exist only

12:11Carl Rowlandson:because of it it always amazes me that within our temperate rainforests we have species that only exist in those temperate rainforests that's how unique they are and we've kind of like devastated then you know there's two percent left and like we're in risk of like making those species extinct

12:24Sam Manning:if we don't kind of what do we have what are we talking hazel glove fungus would be one of them gonna get deep into lichen chap yeah yeah yeah we've got over 3 000 species of epiphytes and we are one of the most nature to neuter countries on earth and that's despite the fact we've destroyed over 90 of it which is mad like carl says you can imagine how many there would have been when we had this sort of belt going up the west coast because that's where the rainforest tends to be it's about 20 of our country and it would have been the west coast it's the shield that absorbs the atlantic effectively hazel glass fungus is interesting because it's a cordyceps so you know the one from last of us it hunts another fungus across the forest yeah very cool quite really weird it looks so weird yeah it literally looks like a glove orange yeah yeah so no no health food sea sponges not that we know of not that we know of well that is the point right studied yeah because it's only like i only know about five or six lichenologists the lichens of these kind of epiphytes that grow on these trees and you have to be obsessed you basically have to have rocket science level knowledge to be able to like find these and there's only sort of a handful of people that are trained up in it so they're absurdly expensive they're incredibly hard to get hold of and they're also you know obsessed with the minutiae so i went out with one once and they spend sort of half an hour looking at one tree well there might be like thousands of trees in one woodland so we definitely know we're not finding all of them

13:42Carl Rowlandson:and they can be like so tiny like i remember going out with a lady from plant life and she showed me this like she was like got really excited i was like where is it and we're using a little microscope to look into it and she's like that's one of the rarest lichens that we have in the uk and like you did you had to like literally look in this tiny little crack in the tree but lichens are like a really important part of our temperate rainforest they absorb carbon they kind of well i don't know i'm gonna start getting off my getting out of my lane here talking about lichens but they're pretty cool so yeah i mean we have a lichenologist called

14:13Sam Manning:Andy Acton he's from Scotland and he frequently comes all the way to Cornwall just to do work for us and he's sort of got this utility belt of like different chemicals he's like his knowledge is so good that he can like put a chemical on a lichen to make it change color to tell what lichen it is he even tastes them to find out what lichen is. Risky business boys. You have to know what you're doing with this stuff but he's yeah he's they're like wizards yeah and we don't have enough of them. No and I sense that from the conversations we've had that you're surrounded by a lot of other experts a few of them feature across the film of course you've had some fantastic panel conversations around the uk so far with dr rian hendy um lisa bt yeah and again like this is where the power of a community comes together and where i guess everything we've got on land with trees and terrestrial where it meets the marine biologists and those with the know-how in in those more kind of aquatic environments i actually want to track it back to the sea and the ocean and the health of our oceans in in relation to this as well we talk about that interconnectedness of this whole ecosystem but where does um there's the lovely term we've used fish forests that keeps popping up what's uh what's a fish forest and how does that come into play in this in this story in japan in the 90s they had this social movement this kind of conservation activist movement called the yotsuki movement which means fish forest and that was led by a guy they affectionately called grandpa oeaster shigeyastu hatakiyama he started a charity called if the forest um the forest is longing for the sea and the sea is longing for the forest so he creates this image of them as like lovers which is really nice and i think speaks to how culturally in love they are with trees and the ocean um but this fish forest is actually it's an actual legal designation so it covers sort of over 60 ,000 hectares across a thousand sites and it legally protects forests there.

16:07Sam Manning:But it's different from what we have here. So a lot of this is what we call SSSI, protected habitat, site of special scientific interest. But that was created in sort of the 60s, 70s to protect what was there from declining. Whereas fish forests protect them because they understand what that forest does for the rest of the system. So it's like a completely different way of looking at nature that's much more aligned with how dynamic it is, how systemic it is. So we think at very much at a site scale and an individual scale whereas these other nations which potentially take their knowledge from indigenous cultures think much more at system scale so that's what a fish forest is really it's a protection but it's a way of just it's an entirely different way of looking at the environment from from what we look at and is that different to what you've coined in way of the flowscape flowscape they have i have a word for this in japanese it's called um i've completely forgotten it's so bad that's the first i just like for records like that's the first that sam b manning has been stumped i've got too many japanese words in my head but effectively it translates to um siblings or great brotherhood okay um at kaya die and the idea is that you know the ocean and the forest are these two great forces that come together and that's when they produce this amazing single living unit and that's what a flowscape is really people can understand what a tree is as a living thing we can see that we can feel it people now because of things like earth rise and and since the 70s we've understood that the earth is a living system but what that's quite intangible and it's hard to touch and but what we're missing is kind of what is the living systems in between that so a flow scape is effectively like a planetary scale tree and rob mcfarlane in his book is a river alive beautiful book like huge influence on the stuff that i do he talks about river systems like the healthard being a tree themselves so the main river is the trunk the tributaries are the branches and the forest and the other leaves and the trees are the leaves and we're taking that one step further with analogy of a flowscape and the fact that the ocean is the soil and species like salmon keystone species that bring nutrients into the forest are like the mycelial networks and we're trying to actually map that at the moment so people can see what that looks like on a planetary scale but the roots would almost like when we've radio tracked well scientists have radio tracked salmon so you can see how they go out to greenland and come back in and you've got that happening with birds and you've got that happening with aerial rivers and there it's just trying to create a new framework for seeing what a living system is instead of managing you know because a forest and even a fish forest is only a fragment of a flowscape it's not a living system in itself it's just a piece of the puzzle and we're too stuck i think in thinking about the landscape and nature as little individual physical things when it's not you know a body is a flowing thing it's not the physical parts of our body that make us alive it's the the flow i think when you kind of told me

18:47Carl Rowlandson:that word it was just amazing because it's kind of the thing that's been missing from our from our understanding of the landscape is that the our ecosystems are working together in flow to share nutrients to nourish each other and to share energy and there's that reciprocity that's happening and it's all connected so like right up in Bodmin Moor where we were the other day right out to the deep ocean that's all working in flow going out to the deep trenches in the maritime ecosystems and then that's coming back up via these kind of mechanisms such as salmon and birds and it's all connecting and that word flowscape is just like oh brilliant that's what we needed to to start like talking about this system because there's no point doing the seagrass restoration if we're not doing the restoration on the land further up upstream we've got to connect it all together and to have that language to bring it together is is i think is is really important i think flowscape you nailed it's better than the japanese word i think i prefer the

19:40Sam Manning:japanese run but yeah and i think like if you take the analogy of the flowscape as a living thing you can center yourself inside of it you can you can align yourself with it you can see that you're part of it but also then see that actually losing the forest is like losing your skin because it's you're losing what's protecting you you're losing what's nourishing you stabilizing and balancing you in a flowscape like this gravity is like the skin because it's the boundary is defined by where the water lands and comes to the healthford and if it falls into another one that's another flowscape and so you can see that they all connect but it's not just about like what the ocean's giving to the forest the key thing that has really come out of this japanese science that i think is the groundbreaking thing is the fact that forests seem to be linked to plankton health or plankton biomass we've lost half of our plankton biomass since 1960 it's a serious issue because they produce half our oxygen they sequester a third of our carbon and that's because of the silo effect of the way that we think about nature it's something that only really oceanographers are thinking about or ocean conservationists but what dr matsunaga in um who i'm hopefully going to go and meet next week i was gonna say you're hot footing at japan after this yeah yeah so he wrote a book called if the forest dies the sea dies which are translated and in that his key thesis is that forests are making iron that they also give to the to give to the ocean bioavailable to these plankton so what he's suggesting is that plankton loss there could be an environmental blind spot which is that that's caused by deforestation which is a huge issue because we've deforested a third of our forests globally you know and we could be missing this and that

21:10Carl Rowlandson:could be the key to bringing back ocean health that's so cool man that the the work that the forests are doing of breaking down those chemicals flushing it into our riparian areas and they're flushing those nutrients out to sea which is then just giving the the basis of life to plankton which is the basis of marine life yeah it's always when you go down here have you swam down here at

21:30Sam Manning:night it's like not at night no the luminescence i don't plan on either but no i have been out with the bioluminescence and it's a well it's a sight yeah it's a real sight to behold yeah i was

21:40Carl Rowlandson:kind of because it's such a kind of the woodlands and everything there and the bioluminescence on the healthwood is like spectacular do you reckon there's there's probably a relationship going on there with the amount of bioluminescence that we have in there yeah in the healthwood i mean not

21:54Sam Manning:to get too techy but there is kind of bad plankton and good plankton and i'm saying this that was my next question actually um the difference between bad and good bad and good plankton and i'm saying this i need to caveat here i'm not an ocean scientist like this is very much me being a journalist environment journalist but that generally there are good and bad plankton and when you have an unstable flow scape because of a lack of trees or too much pollution input which can also be because of a lack of trees you know because like when it rains and there's these sewage overflows that because because the land's not holding enough water you get these surges of what they call red tides which is like flagellates so these kind of plankton which grow like bacteria really quickly in response to pollution.

22:34Sam Manning:They choke out everything around them. Yeah, and they tend to be the food of the jellyfish. So that's where you get these jellyfish blooms. But when you have stable flowscapes that are healthy when the water quality is really good, you get diatoms, plankton, and they underpin the fish food ecology. So the more diatoms you have, the more healthy, stable kind of balance of plankton you have, the better fish populations you have, in combination with these essential fish habitats, you can call them these kind of mangrove ecosystems where you have kelp and seagrass and forest coming all together. And kelp and seagrass, we've lost about 80 % of that as well.

23:07Sam Manning:So not only have they become disconnected, they've become very fragmented. But in forest conservation, we're never thinking about how forests are connecting to kelp. And that's what's new about this, I think.

23:15Carl Rowlandson:So these woodlands here are filtering the runoff from the surrounding land mass and stopping those kind of big algae blooms that are happening from all the fertilisers. Is that kind of...

23:25Sam Manning:Yeah. So Ian will say that if you put a 60 metre buffer on a river, it will reduce 90 % of the nitrate inputs from the runoff. And the Woodland Trust are doing some really interesting work at the moment, looking at flowscapes and how they function to see if there's any parallel between the work they've done in Japan. Because in Europe, we've done nothing like what they've done in Japan scientifically. And what they're finding is when you have a really deforested system, having that buffer is really, really important to protecting the water. But actually that our flowscapes have turned off. So they're not working in the same way that they are in Japan.

23:56Sam Manning:and what we need to find out next is what's like the critical mass tip positive tipping point how much do we need to reforest to get them to start turning back on again but yeah we it's becoming clear that forests are incredibly important to marine health and we just it's just it's just like we're just trying to take back the curtain now and really understand more of that well for someone who claims not to be a marine specialist you really do know your stuff um honestly i could listen to you guys speak for hours and this stuff it really is you're so well versed in it you we've spoken about japan quite a lot and you're off tomorrow yeah two week trip yeah um as part of a an additional another another film project that's happening on around the same conversation yeah that's right um but you've never been to japan no you've translated a japanese book which is kind of the birth or the origin story of this for you there is obviously a culture there that has a reverence for tradition and slowing down and patience and respect for nature, incredible respect for nature.

24:57Sam Manning:You've spoken a lot about tree culture already today. It's other than being out there to film, to speak, and to connect with these people in real time. And the wisdom, we talk about science, we talk about wisdom and the intersection between the two as well. Then you have storytelling. The Japanese are incredible storytellers. I mean a you excited and and b what else do you hope to gunna garner from this trip yeah I'm very excited I'm I mean the book the book's gonna the book's gonna be called flowscape the hidden connection between oceans and forests and that hidden bit's really important for me because that tends to be the most exciting that curiosity-led stuff um is really exciting but I suppose what I'm looking for you can only do so much researching remotely to understand a culture and you know a lot of this has been about the science it's been about what happened there but I want to go a lot deeper with that and I feel like journalistically it's only going to a new place as an outsider that you begin to see the stuff you can only really get from being there and being part of it which is kind of like the space between people how they interact how they think what you know and like you say just why have they got that love that tree culture that we just have lost for some reason what is it about the way that they relate to each other the way they relate to nature, the way they see nature, all of those things you can't really garner from books and you can't garner from research and science.

26:18Sam Manning:You have to see it and feel it in people, which I think is like the purest form of journalism. So that's what I'm going to find out really, is I want to understand how have they managed to retain this forest cover and this connection and how are they able to see as a people that connection between oceans and forests where we can't. And I think I'm hoping that if I can work out what that is, I can bring it back and it can help the campaign it can help people because this for me is not just about like saving you know nature and reconnecting nature it's about it's about helping people i think i don't think there's difference between mind and nature i think that they're completely linked and i think people are unhealthy and depressed and sad because nature is unhealthy and the two have to be restored together but you do that by changing the story that's in people's heads so that's that's why i think this is so critical because i want to understand what the story is there why do they see the world differently and why are they more in balance with their in their minds but also with the natural

27:12Carl Rowlandson:world any exotic trips in the pipeline uh i'm going to wales to see my parents soon yeah good uh yeah not to japan but wales another rainforest celtic rainforest country there you go yeah

27:26Sam Manning:actually bringing it right back why cornwall obviously you guys are based down here your are based down here is it just coincidence that this spot outside the window here is such a gleaming example of restoration an ecosystem what we must protect yeah why cornwall and does this thing have roots and shoots far beyond i mean i know it does but perhaps to explain that well

27:54Carl Rowlandson:100 i mean we often refer to the temperate rainforest as the celtic rainforest this would have stretched all the way up through northern europe into cornwall up the celtic countries you know covering the isle of man and covering most of ireland as well um but why cornwall for me as a woodland crater this is where the need is greatest you know this is literally the most deforested county in the most deforested country and we have this real kind of rich history of and rich culture of the maritime habitats you know fishing surfing wild swimming real livelihoods real livelihoods based off of the um ecosystem services that the maritime provides but we completely deforested the county and so there's need for reforestation and then when we pair it together with the work that sam's doing and understanding that the forest and the ocean are connected well how are we going to successfully put seagrass back into the healthwood without answering the question of reforestation on the land so there's a there's a real great need for the work that we're doing here in Cornwall but I think personally I think we can use this as a test for the rest of the country if we can successfully turn those flowscapes back on in Cornwall then we can roll this out to other counties and we're in those conversations at the moment there's a Dorset project that's going live I've been over to the Isle of Man talking to them about the work that we're doing here as well and people are starting to use this kind of understanding within their restoration approach so for us doing the impact of this campaign and and this campaign is all about storytelling it's about the science and it's about the impact and we're trying to deliver that it's about showing the rest of the country that if we want healthy rivers we want healthy fish nurseries we want a lovely marine ecosystems then getting some trees in the ground is a real tangible way to make that happen yeah yeah your question was like why Cornwall

29:46Sam Manning:and I think about this a lot because I've like lived and worked and done rainforest restoration in scotland wales devon and all of those ecologically are very similar to here but i think cornwall is kind of this like it has this perfect storm of factors which i think created helped create this campaign so you've got the rainforest obviously um and the restoration work that's going on there and all the great charities that are doing that stuff but you've also got this really unique combination of people that are very connected to the ocean i think in ways that i don't see anywhere else in the uk you've also got this absurd um not absurd but like remarkable concentration of creativity and creatives like since covid i feel like we've drained bristol of all of this creativity which is amazing it's like an amazing time to be here and there's so much stuff going on but also it's like it's got this the landscape is so degraded that it's almost like there's nowhere to go but up and so we can and we've got these we're on the front line of these issues like flooding and fish decline and all of these things and when you combine those it's the perfect place to tell and kind of incept this story like three years ago i went to Vancouver Island and spent some time there and I just kept thinking this is like Cornwall but with trees and I started feeling this real yearning to go back to Cornwall I really missed it but I also just felt this yearning for Cornwall to have trees again I just thought like about the image of like going to Gwyvian or like Porth Tawen and just walking out of the trees onto the beach would be so cool and I think a lot of people want that I think people yearn for that they have a huge connection to the ocean here and they perhaps have no conduit for connecting with the land because you know there's all this discussion about we are nature and like you know reconnecting of nature but you can't reconnect with what's not there anymore and actually you know trying to connect with a field with a sheep in it is not working because that's not nature you know these rainforests are nature and they're what cornwall would have had and they're they're what cornwall would look like if it was functioning and really well i think health and being healthy the amount

31:39Carl Rowlandson:of times i've heard people say oh yeah but cornwall doesn't have trees like people stand you know looking across the beacon on St Agnes and just seeing the rolling pastoral landscape and think oh no trees can't survive here it's too windy it's too windswept or down at West Penwith where there's no trees it's completely.

31:55Sam Manning:That's an extreme example of the shifting baseline.

Read the full transcript

31:58Carl Rowlandson:Exactly that yeah and it's amazing that we have those conversations and people don't realize that there would have been this woodland cover that would have been hot you know really high not that long ago and would have stretched right down to the coastline and we kind of completely pinched back so yeah you mentioned about the challenges it's about telling that story about how we need those how we are a woodland county and how we are a forested island and bringing that back into

32:22Sam Manning:people's kind of consciousness Derek Gale has this great book called Hump for the Shadow Wolf where he talks about how culturally we've made we've ostracized wolves and we've made them see them this kind of dangerous negative thing but that only really started happening like after the 11th century and I've got a feeling that we've done the same with trees you know people think they love trees but actually they don't want them blocking their house or they don't want them in the landscape or you know there's this there is a stigma against them that's almost more insidious than the anti-wolf thing because we don't even see it i heard you say earlier tree derangement yeah i haven't quite landed on that term yet but i think but i think like it's like you say the the shifting baseline syndrome it's so true it's almost a syndrome it's like it's a kind of silent psychology and people might say oh no british people love trees well why are we so deforested and when you ask that question there's almost no answer for it and i think that for me is the most interesting kind of journalism it's like tacit silent elephants in the room you know why are we not talking about this as a nation like why is that something that's pushed under the carpet why is there no answer for that that's what is so exciting about this campaign for me it's kind of digging down into that that question what we love doing in the uk is cutting the trees down

33:30Carl Rowlandson:putting houses on it and then naming that housing estate after the trees that were once there Or willow close. Yeah, yeah. Ash tree close. Yeah, yeah.

33:38Sam Manning:Or that with no trees there anymore. And we're building 10 % of our new houses in floodplains that are flooding because there's no trees. You couldn't write it. Yeah. At a time when we need nature as a defence, not to strip it in, you know, in anticipation of actually everything that's about to come. I mean, we were up against a year this year with El Nino or El Nino? El Nino. El Nino, which is, you know, nine to 12 months of weather extremes across the globe. So as far as nature-based solutions go, we need to be doubling down on initiatives like this and protecting these wild places.

34:17Carl Rowlandson:You can see it here when it's raining. And especially this winter, we've had one of the wettest winters ever. You can just see all of that soil piling off horrible fields and straight into the river. and the river turns brown when it's been raining like deep brown and if we can just do what you were talking about what ian hendy was saying putting that riparian buff those woodland buffers on the fields it's going to put that complexity in the soil and help keep that keep it in place because you drive up there when it's raining and it's just piling down off the fields smothering

34:48Sam Manning:the seagrass the analogy we've started using is we've ripped the roof off our house that's what the forest and the upper catchment are and now there's a storm coming and if we don't get that roof back on in winter we're going to be wet way too wet and in summer we're going to be way too hot and that it's as simple as that they just stabilize the environment yeah we used to have a thatched roof and now we've got a slate roof and everything's just piling off it kind of thing yeah we've lost that complexity yeah mine's a spesto cement roof so it's um i'm worse off than all you um we've spoke a few about a bit about the stats and the numbers and you know what the cornwall eight percent forest coverage in cornwall where does plant one and the no trees no seeds initiative want to get to what's the three-year plan what's um what does coverage look like uh best case

35:34Carl Rowlandson:scenario so we've got a we've got a mission and vision to reforest and reconnect that's kind of the the goal of plant one and we've set ourselves a 3 000 hectare target over the next 20 years and we want to use the next five years to look at high priority areas these key areas that that sam is identified within the flowscape where if we reforest these these are going to have a multitude of benefits to not only the land the riparian but the marine ecosystems as well so over the next five years we're now going to target those areas look at the mapping and look at the research and say right where can we approach these landowners to get these trees in that are going to support all of the other restoration efforts that are going on i think you touched upon it before there's often kind of a bit of siloed approach to restoration in this country but what we want to do is speak to the seagrass people, speak to the kelp, the people that are doing the mill bed restoration and say, okay, so where's the problematic areas that's causing your desertification of your restoration?

36:32Carl Rowlandson:We want to go in, reforest those areas so that the work you do is going to be supported by the forest. So yeah, the next couple of years, we want to start getting 100, 200 hectares of woodland in those high priority areas. And for us, we're focusing as a case study on the fall and the Helford flowscapes. so yeah come along and plant some more trees larry well we did didn't we though wasn't so

36:55Sam Manning:much planting but actually um maintaining maintaining and news to me when i rocked up we wouldn't be planting but weeding trees which is yeah very important so it's um yeah we had a great team day there last week uh and that's the that's the key though is is is not just sticking

37:13Carl Rowlandson:the trees in the ground and walking away you've got to do that long it's not that it's not a pat

37:16Sam Manning:on the back it's not great cool yeah and i've read something or heard something you said earlier it's plant one we create woodland rather than plant trees yeah and very subtle but a big difference right yeah i mean you're creating something that will actually you for sure why don't you tell me

37:32Carl Rowlandson:what your words mean but yeah for us it's it's putting the trees in the ground is step one the approach that we take is is managing the land and then that could mean managing the herbivores but encouraging that natural regeneration to come in as well. But it's the long-term piece. So up at that site on Bodman, Kabila, we've got a 15-year agreement with the landowners. So we're going to be there year after year to ensure we have that longevity, maintenance and management. And that's the kind of key piece. That's the bit where we can step away and say, right, there's a young woodland burgeoning there.

38:03Carl Rowlandson:But yeah, that's a cool site. That's like right in the middle of Bodman. It goes back to what Sam's saying, the tree planting that we're going to do there, woodland creation work we're going to do there has a direct impact on the foy flow scape. You know, it's going to impact all of that ecosystem.

38:18Sam Manning:One of the things I've come to really pick from this is, if I focus back on Cornwall again, which is so easily done, everybody gravitates to the coast. You think Cornwall, you think coast. You think the beaches, you think the inlets, you think the cliffs. I spend, maybe I'm generalising here, but I spend very little time in the interior of Cornwall. um in fact kabila is a place i spent more time in the interior a it's beautiful but it has the river i don't feel too dry when i'm up there um the is it the bedalda bedalda yeah it's uh it's magical there is you know merlin who uh looks after the land up there steward steward of the of the forest speaks about it very romantically it's the river the forest and the river is is merlin in a way it's uh it's very spiritual there's a book on the table here our oak and bones it's an amazing story can i jump on to the point about like creating woodlands just because i think yes please because you know the people would assume two things one that this is again about just planting trees but it's not there's this crazy stat that i keep coming back to they do this thing called the state of nature report every five years where they just check the state of nature the last one they did was 2019 i think and in there there was this crazy stat that that said between 1840 and 1880 so that's like the height of the industrial revolution when we were really kicking off with like deforestation we drained an area the size of dartmoor every single year in the uk drained the soil and then we did the same thing again in the 70s so this isn't just about planting trees this is about like recreating woodland that's wet so so rainforests are wet you shouldn't really be able to move easily through them there should be so much water and there should be full of necromast like huge amounts of like deadwood because if you go through a forest in canada you can't move through it there's so much old growth dead wood and trees and stuff and that is what a healthy woodland looks like and it's it's able to hold water so actually this is not just about planting trees it's about creating what we call biogenic forests which are able to like reabsorb those and be really healthy and you know that's all part of part of the story really

40:18Carl Rowlandson:as well isn't it yeah that kind of when you explain it to me like what would a river be if we'd not messed with it it would have a woodland that run alongside it that woodland would have decayed died grown up again trees would have fallen into it it would have slowed the flow of the water down there would have been beavers in there and you start kind of understanding what a riverscape actually is and the woodland and the river are completely intertwined yeah

40:41Sam Manning:we've been really inspired by a movement in the pacific northwest called stage zero restoration where it's like it is seeing that all of our watercourses are really artificial and anthropogenic and that we've drained the land and actually what they're doing there is just restarting rivers and it's remarkable what happens when you do that because you just get this complete you know restarting of the system and it slows the water cools it makes it better quality and forests that's what forests do and also other species like beavers and and deadwoods and stuff i went to a place in vancouver island called lost shoe creek and from the beach to the headwaters i just could not see the river there was just so much deadwood in there and matsanaga in his book he says that if you've got a healthy old growth forest like that a square meter of that river should have 10 grams of invertebrates falling into it every day so bugs for fish and you look at our rivers i mean on the main river like this you wouldn't have it but in some of the side tributaries there's just no wood half of our woods in the uk have no deadwood in like when i was in when i was in canada as well we'd be out in the boat on a place like this and we'd be hitting logs you know every every minute with the outboard would be getting slammed but i mean that never happens yeah slow in the flow with the

41:45Carl Rowlandson:deadwood that's going into it yeah yeah yeah absolutely fascinating and like so in that lost Shoe Creek that just went straight into from from the forest to the river in straight into seagrass

41:55Sam Manning:yeah it wasn't like an expanse of mud the division between the forest and the river is not there it just flows in and then the division between the sea and the forest is not there because you go straight out into seagrass and kelp and you can kayak over it for you know kilometers and then that's that is one continuous fish habitat which is what Ian Ian Hendy talks about is that you have like the salmon which are a woodland animal and when they come out as juveniles they spend time in that kelp and that grass, seagrass. And the kelp protects the seagrass from wave energy, so you need to have it all together.

42:25Sam Manning:And then they will go, okay, this year's good. And then they'll go out into the ocean and they'll come back. But a poor fish in this river has got no habitat, spawning habitat. The water's way too fast. It's too warm. It's too full of pollutants. They then come out to where their nursery should be and they're not there. So then they go straight out to sea into a warming, acidifying ocean. So at every stage, they're being set up for failure.

42:45Carl Rowlandson:Yeah, yeah. They're getting predated on by seagulls. Yeah, exactly. Yeah. The migrationary journey of a salmon and when you kind of described the role that that plays within our woodlands, that was the kind of, when I really fell in love with the kind of connections with the forest and ocean because it's fascinating. They're, as you say, woodland creatures. They forage in a deep marine environment. They get to our freshwater. They stop eating. So they're just taking all of those marine nutrients into our headwaters, swimming up to the woodlands where they spawn and die en masse and then spread across the woodland floor.

43:18Carl Rowlandson:And those marine nutrients go back into the soil. I just think that when we were up at Cabilla, that Bedelda would have been teeming with salmon. And if you were a woodland rainforest tribe, hill tribe, it's amazing once a year the the ocean would deposit itself right in the middle of bogman and just be scattered with salmon all over the floor it's i think that's just so i think it was lisa

43:41Sam Manning:was telling me about she's she's found like sort of records of people complaining about having too much salmon to eat because they used to be paid in salmon so they'd be like can we please have something other than salmon you know this is like it was a huge part of the culture um but yeah when i was in van island as well i spent a lot of time with conservationists who take a lot of their knowledge from the natal youth who are the first nations there and they literally call themselves the salmon cedar people they completely base their identity around the salmon and around the cedar tree and in our growth forest there and they only have 10 left of that so actually they're in a similar situation to us in terms of that decline now 25 of the nutrient in that tree if you measure it will be from the ocean so there's this in the biggest influx of nutrients in between any biome in the world happening there that would have been happening here and it's gone that link is super important there's a there's a guy called ted green he's like sort of a legend in the tree world and he does a lot of work on chronic and acute oak decline which is a disease we actually don't know they either slowly start to die or they completely die very quickly and nobody really knows why that's happening but his theory is it's it's malnutrition it's soil malnutrition and that actually these these links that we would have had at a system scale mean that our soils are becoming so degraded of micronutrients that the trees themselves are starting to die that's one of the theories and he's proved that actually if you kind of make this iron fulvic acid rich tea which is what's which is what matsanaga is saying forests are doing to the ocean you instantly see the tree come back to life and i think there is something to that we talk about shifting mindsets and the power of storytelling no trees no seas is a beautiful film could have been much longer arguably it's had a fantastic reception but what where where does storytelling play a role here and not just telling the stories that we have right here on the river or the work you're trying to do but the stories of others and the wisdom the indigenous cultures the the the universal nature of no trees no seas i like i'll talk about like sam crosby's amazing work but my view on this is satish kumar who's an amazing writer really inspired me he has this saying that if you want to change the world you have to change the story and i think one of these huge problems that we've had in the environment movement is we've sterilized it of story we focused on messages often quite negative messages and those are just almost quite linear you know barrages and it just doesn't connect with people a story has an arc it's a restoration arc you know this is what we used to have this is where we are now this is where we could be and I think bringing that now into the environment movement is super important and finding the people and organizations that can do that's really important but I don't know if you want to talk about Sam yeah absolutely I mean

46:08Carl Rowlandson:it goes back to the kind of the three pillars of the the campaign that me and Sam created when we when we start no trees no seas and that's storytelling science and impact and I feel science and impact on its own you need the storytelling because that brings the community behind you we need to start telling these positive stories and also reminding ourselves who we are and where we've come from and connecting back to the past so without that mythology and well those new stories we don't get the culture and we need that cultural shift to become that mass tree planting kind of culture once more uh you know i love that quote um to catch a fish you got to plant a tree and we need that kind of storytelling happening here again so so the campaign we felt early on needed that storytelling element we brought on a really fantastic mythologist called sam cosby and that's the kind of the words in the film he's the one that crafted that that sits alongside the animation and one of the beautiful things he says is when myth and science agree that's wisdom and i just think that's brilliant and to look back in the past and be guided by the past and shaped by the science is exactly what we're trying to achieve here and i always think you know sam talks about this is always fascinating whenever you look through mythology salmon is always featured you know people knew that salmon was this special amazing creature because it migrated through all of those different habitats no other creature did that so it's amazing to look back and see those references of salmon within in the mythology but for us we want to connect to the communities and we want to tell those stories and we want to bring people along and change that change that shift and start telling a positive story because as chris haynes says he's one of one of the ambassadors you know we can do this we've just got to recognize and remember that we're the team we are the we are the kind of people that can make

47:54Sam Manning:this happen yeah i think there's something really important there about we've we've got a society now that's obsessed with certainty and scientific certainty and what that tends to do is it freezes you in stasis until you've got the answer which is not coming often and it also disempowers people that kind of certainty when you're in a crisis you need to just trust intuition and intuition is really empowering to movements and people and that's what i find in storytelling is it just gives you it empowers you to be like you know what's right you know that bringing more trees back regaining forests reconnect of nature is right you don't need science to tell you that it's not it's a really long no yeah and just just trust your gut the amount of people in in the book right the process of writing the book i speak to a lot of people who are who are maybe seen as mavericks in the environment sector because they are pro-planting trees, bringing back beavers, doing rewilding.

48:41Sam Manning:They're systems thinkers. And they're often vilified by the expertise section. How so? In the sense that this is going to get really technical now. I think what I think is happening right now is we're moving from the old school conservation movement, which is about protecting a kind of degraded state and stopping it getting any worse, which I think has failed. which was also you know these laws and were you know protection legislation but these these were things that were drawn up in the 60s and 70s right that actually for in many instances haven't changed for decades and and super important you know those have protected species from being lost almost certainly would have but what they that but they're built inside a framework of siloing of stasis of misalignment with nature which i think the whole of society has got right now and i think we're moving from this preservation conservation world through to restoration and that is about radical systems change land use change more trees more forests more beavers rewilding focus on water holistic break down all the boundaries all of that stuff all the stuff that you see in the pacific northwest and i think hopefully i'm going to find in japan as well and and although both are necessary because you need to have a systems change to you know to restore the environment but also protecting those key species there is this tension there still at the moment and that's what i'm most interested in exploring the book but you tend to get sort of people that are in the old school conservation almost kind of feel very cautious about this new restoration movement and those that are advocating for it and doing but they're often doing the really cool stuff the stage zero the rewilding the tree planting and that we are going to have to rectify those two things but all of the people that i talk to in that restoration space they describe uncannily even though none of them know each other this idea of a gut feeling it's an intuition that actually we know what's healthy you know in the same way that we know that you know fruit and being outside of being in the sea is healthy we don't need science to tell us that but we're stuck in this world where we need to have that certainty or be told that that's what's good for us and i think there's something really powerful there yeah we need to push back past that

50:43Carl Rowlandson:managing the decline definitely and i think that's where kind of story comes in yeah stories of hope and change and then examples of that done right and also if bringing back reverence for nature as well telling those kind of you know you're not going to cut a tree down if you think there's a powerful witch that lives in there and they're going to take you down to the underlands or if your ancestors are in it yeah yeah or if your ancestors are in them yeah exactly so i used to uh i'm just thinking of tree beard now yeah yeah but why is tree beard but elders are uh like in cornish folklore one of the most powerful trees if you cut down an elder you're kind of in deep shit because the woods witch is going to come and drag you down to the hell there and like as a tree surgeon i'd be climbing a tree and there'd be like an elder because they're kind of shrub species growing next to the tree that we're working on and i'll see like the ground worker go to like cut it down i'll be like oh you don't want to cut that down you're going to piss off the woods which if you do that and he sees like sort of big tree surgeon guy go to get his chainsaw and then he'll sort of back away a little bit and you'll be like see you're a little bit scared of trees it's all right bit of reverence and a bit of fear someone told me

51:47Sam Manning:someone told me that in ireland there's a kind of um there's a specific reverence for hawthorne or a special reference for Hawthorne and you get these groves of Hawthorne in the landscape and there's a there's there's a folklore about not cutting them down and when they have ignored that and gone to dig it up they found their anthrax pits so they're where sort of like very very like you know a thousand two thousand years ago they were burying animals with anthrax and they were putting the Hawthorne on there to stop people digging them up again and they used myth to stop people digging them up yeah because I think Sam Crosby says um eventually myth becomes truth in the end yeah because it has this it has this way of bypassing our brains and and just making us have reverence reverence is the word yeah it creates reverence in us in a way that actually a sort of linear kind of literal warning would not i think yeah yeah exactly i mean yeah 100 %

52:37Carl Rowlandson:and you it's fascinating that they embedded the story as a warning into the into that into that hawthorn but yeah you're not you're not going to pollute the the hellford if you believe it's a

52:48Sam Manning:goddess if you actually believe it's a goddess or if you see that you're tangibly linked to it yeah that's the problem we don't realize that actually when we're polluting that water it's

52:56Carl Rowlandson:polluting us yeah yeah yeah yeah that severance is a problem yeah bring back reverence yeah

53:01Sam Manning:severance yeah yeah pre-reverence yeah yeah full of sayings okay i can't keep up guys i'm trying i'm trying the last like i said the last year 18 months has been a roller coaster it's been everything's happened in quick time you guys are relentless this is really admirable the what have your biggest wins been like where have you if you had a chance to sit back and go you know what like this we're actually really making some change here we're connecting people and projects we're joining the dots together between land and sea yeah what what have your biggest biggest takeaways

53:35Carl Rowlandson:so far been yeah i mean it's just seeing so we we crafted this film together and you know it's fantastic having the kind of support that you guys have brought along to that and for me it's just watching the reaction of of of delivering that story to people and when we do the q and a's afterwards people are so engaged with it and it is it is that kind of people just kind of get it you know it's not like well this doesn't make any sense or you know please deeply explain the science behind this people intrinsically get that connection is there and it's just fantastic putting that out and telling that story and feeling the thirst that people are craving this story.

54:14Sam Manning:I've been privy to a couple of standing ovations. I have, yeah. Eden Project got one. That's not a given.

54:21Carl Rowlandson:The film is beautifully made and the filmmakers James and Ross from Lightbox, they did a 100 % shout out to those guys because they put it on the line, did a lot of the work for free so yeah, 100 % shout out for them. But just seeing the response that it's getting, you know, it's a good story and it's a good news story.

54:41Sam Manning:Yeah, I'd agree. I think because we're in this movement, like I say, from this conservation to this restoration, what's going to try and bridge that is stories. And I think people are desperate for the language, for the story to help them transist. And that's, I think, when it's like Carl says, when you see it in people's eyes, when you tell this story, they can relate it to so many things in their lives. because ultimately it's a story about breaking down silo and it's about reconnection with nature and finding agency and intuition that's what really the story is and people can relate that to anything that like modern society has taken away from them and yeah i've had people we've had people come up to us and they just say it's this so clear this is what i've been looking for in the same way that this is what we were looking for you know this we found this story as much as anybody else was looking for it now and it's emotional it's emotional to see people find that but i think also for me like the biggest there is the obvious thing to say that because that's because this story has come at the right time we are seeing policy change now we are seeing people in in the right places in government start to go yes i see how we can start to move this into policy um it's definitely changing the conversation in the conservation sector which is the positive i would have liked to have seen but i think for me like the biggest win is just the community it's building i thought i think the only way we shift the dial on this is we rebuild community and meeting carl meeting all the people that has worked on this like the hundreds of hours that people have put into this for free you know just purely around the passion of it because they know they feel that it's something that's important has been like it's been the biggest pleasure of

56:05Carl Rowlandson:my life i think yeah it's truly a collaborative process and and you know all we wanted to do me and sam was put a flag in the sand and let people know what they're doing and open that door and people have come along and helping to roll it forward and and to take it on next and i think the the positive thing here is we've done this before we were down to two percent woodland cover at the turn of the 1900s at the back of the first world war we managed to get woodland cover up to eight percent so we increased it by six percent a lot of that was forestry but we can replant again on that kind of scale and we can do it quicker we've got the story we know how to to successfully reforest this land so i think in the next kind of generation we are going to see cornwall become a reforested nation again we we can definitely make that happen i think

56:53Sam Manning:Cornwall and beyond there's an amazing writer called Lou Asprey who lives in Cornwall and she's got this idea of proliferation events so you have moments where systems are really really unhealthy and a willow for example when it's unhealthy will just expand seed into the landscape and that effectively would look like a mass reforestation event and I think that's what we need but we're not going to do that through a petition or through a project, that needs to be something that grows in people as a mass movement that they get up every morning and they're like i can't be happy until i see this reforestation thing happen and that's culture change that's what i think we need to see there's a real systems culture shift people need to fall in love with trees again i think yeah

57:35Carl Rowlandson:yeah yeah it's amazing when i speak to people and they they come up to me a couple of weeks late and they go so i drove past this kind of field and i was like that could have had trees and that should have trees you know people start seeing the landscape in a different kind of frame And I think that's what we need. And we're not here to completely reforest the landscape. We just want to work in those areas that are going to have the maximum impact, retain our farming landscape, thicken out the hedgerows, put in those high-priority woodlands.

58:00Sam Manning:And that's what we did with you last Friday. We weren't planting across the entire field there. It was strategic. You were trees around, supporting trees around other types of trees. Leaving grazing areas. Local trees, native trees, of course. Yeah, yeah. I remember leaving, I think we left a big old patch in the middle for the beast of Bombin Moore to come and collect its deer. Yeah, indeed. That's a different story. That's a different story altogether. We've had a lot of great conversations with landowners and farmers through this. And it would be nice eventually to talk to fishermen because this is ultimately a story about food security.

58:30Sam Manning:Yeah. From both at Land and Sea. And I think the best conversations of when we've been able to meet in the middle and say, look, we're not talking about solid forest here all the time. We're actually talking about, like you say, individual trees and fields within which you can still farm, but actually also protects farming from climate change and makes that a healthier, less input, more resilient business. But equally, you know, one of the big problems we have is there's actually too many trees in a lot of these woodlands. They've become moribund. And actually, a healthy landscape is one that is blended.

58:58Sam Manning:So you have more trees outside woods, less trees inside woods. It's hard to see the edges of things. Edges are not good in nature, but also they're constantly changing and shifting and being dynamic. and you've got animals going through them. And that's what our landscape would have looked like in the Celtic period. You would have had farmed animals entering woodlands, going out into open bits. It would have been so dynamic in the same way that our bodies are dynamic. And I guess that's the coming back to this flowscape thing is what we're trying to show, that by siloing off the landscape and having solid woods and open habitats, it's the cusp of all of the problems we have environmentally.

59:29Carl Rowlandson:Yeah, I think agroforestry is going to be a real kind of silver bullet to a lot of this. So putting trees into a farming landscape where we can have those grazed areas within that kind of woodland mosaic i think is going to

59:41Sam Manning:really help i might show my age here but i've some reason i've got images of animals of farthing wood

59:48Carl Rowlandson:you remember that tv show is that the with the raccoons no that's another one though

59:55Sam Manning:and cyril sneer has uh still needs to pay for pay for the rickets um anyway listen we've got a couple minutes left and there's actually a couple of things that would be good for you both to plug a your book sam that's incredibly exciting that you're writing when do we expect to get a copy of the uh transcript so this year is about the traveling the the journalism part um next year is going to be about writing it and i'm hoping it will be out sort of neck back end of next year which should be really exciting yeah amazing yeah i also need to give a shout out to the woodland trust because so much of the research they've done has pushed this stuff forward you know amazing organization and yeah really central to this yeah and carl uh crowdfunder yeah so i guess

1:00:41Carl Rowlandson:the two kind of things i want to shout about is the yeah the crowdfunder and uh supporting plant one so we we've launched crowdfunders sit alongside the film screenings that we're doing which is all about bringing the resources in so we can create some of those fish forests that we talked about we need to get a woodland creation officer in post and that's exactly where that finance goes so we can go out and be proactive look for those high priority areas and create some of those fish forests that we talked about so that's just come on we just launched that now um it's called no trees no seas fish forest um and then we've got the screenings that we're doing with you guys and some other venues across the uk so yes stoked to to to go along those and get people to to come and

1:01:22Sam Manning:see the film so yes screening the first one is this friday the fifth so this that may have come and gone by the time this airs. Otherwise, the 11th and the 12th across various other participating schools. So, yeah, should be great, really. It's a very, very stirring film. The illustration work, the talking heads in it, the Chris Hines, the ocean, the land. It's incredibly inspiring. You've done a tremendous job in turning that around so quickly.

1:01:54Carl Rowlandson:But, yeah, I mean, it's a collaborative effort. You know, we need the kind of support from organisations like any. So big thanks, Larry. Yeah, really, really appreciate you, mate.

1:02:02Sam Manning:Well, great. Listen, I absolutely love spending time with you both. I've loved watching this thing grow from seedling to what, you know, this... Mighty oak. Mighty oak. And thank you. Thanks for, you know, everything you've shared. I appreciate it. Cheers, everyone. Cheers, guys. Well, I hope you enjoyed that one. What Carl and Sam have laid out isn't just a conservation argument. It's a reorientation. A reminder that nature doesn't recognise the borders we draw on maps, the river doesn't know where the forest ends and the sea begins, and neither should we. No Trees, No Seas is a campaign rooted in science, but it speaks to something older than science, the understanding that everything is connected, that what we do on land arrives at the ocean, and that protecting one means protecting the other.

1:02:51Sam Manning:If this conversation stirs something in you, I'd ask you to sit with that, to share it, talk about it. And if you want to go further still, Get involved with No Trees No Seas and the campaign with Plant One. Links are in the show notes along with more of the No Trees No Seas campaign and the science of the flowscape. Thank you to Carl and Sam for their time, their clarity and their commitment. If you want to really see how passionate these guys are and how they talk and how they work, tune into the video version of the show over on the Finisterre YouTube channel. Thanks to Gareth and the team over at Chatterbox Audio for stitching the show together.

1:03:24Sam Manning:Sound design by CJ Mirror. and thank you for listening to Hello High Water. Until next time, the work continues on land and at sea.
