three quarters of all londoners are now significantly affected by human activity the few remaining pockets of wilderness left are themselves at risk of becoming ecological deficits. i would call to industry urbanisation climate change and hunting all these days he. made

eco systems and destroyed by a labour city. % of the world's animals population have been wiped out since the nineteen seventies. scientists claim that the planet is witnessing a mass extension. in response a worldwide movement is now under way to re why the countryside to restore lands an eight to one in the city at the tip of south america. is exceeding all expectations. i have come to but i only have to meet chris tompkins apply for bass with dedicated the bus to the gates to the protection of this area. the conservation projects to study with the husband doug has become a true inspiration to those who believe the wilderness can heal itself. if given half a chance. but the colonia east of basra region of

mountains and forests spawning seldom cheat in argentina. though famous for its a stunning landscapes for centuries it has been an important region for livestock farming and many of its growth plans have been great yeah. at the region's hot lights patagonian national park. i'm here to find out how these became one of the biggest conservation projects in history. hello hello nice to meet yeah i me and i'm chris calkins but are you a little do. former ceo of their company but that only a priest married doug tompkins an interpreter and adventurer who had found the driver brand the north face. both friends made them by your mentor protection center to their company ethos but chris and doug wanted to do more. from the early nineties both over three hundred million u. s. daughter so plan for

preservation christianity and tina. they build parks complete with lodges campgrounds and trails to support a good two recent. after dark sudden death in twenty fifteen preset gary demanded as. president of their foundation thank yous conservation. what was it you saw here may you take a decision that would change you know the next twenty years. i didn't see it frankly dog is the one who's side. he sought a landscape that was beat out and miles of fence line to take down and dug convincede this was the conservation chance of a lifetime. in two thousand four in the technical valley crease and dog bought these cheap branch of almost two hundred thousand acres of over grace grasslands. they said about pretending it in a to along with a handful of smaller farms using a process called rewilding. rewinding is the

restoration of an entire ecosystem to its natural state by removing foreign speeches white green to houston and protecting native ones. it begins with the removal of livestock that we needed to get a sense of flurries. these encourages in six and early ninety miles attracting birds another one predators. removing fences allows the return of her before which are preyed on by apex predators those at the top of the food chain. with them so much like. speeches in critically low numbers will totally absent a rehabilitated ultimately spray i'm predator populations regulate one another. and the ecosystem. equals into a balance themselves to stay in the wilderness. when we bought this property there were probably. five hundred miles of fence line. that needed to come down and when you take the fences down you see wildlife coming back again because for eighty

years it's been excluded from the best grasses. chances are to keep. wildlife. out of the best grasses and keeping your. livestock in t best grasses so it's very exciting to see the grasslands and the forest begin to restore themselves. and that's the joy of taking fences down. one ninety my benefiting from these grass is that when i go close relative of the llama and a keystone species that he's one that plays a crucial role in the functioning of the ecosystem. it's not often you see one by itself. they're pretty emblematic of the patagonian step if they're plentiful and they're calm like this one is. then you know that the system is coming back and that they feel no threats. of course and that's what you're going for you. i want to see what

rewilding looks like up close. let me pasta they say there please cancel still. the parts they rector of conservation has agreed to show me. priest and has been a guiding hand on the revising process is the parts beginning so no one knows the flora and fauna here better than him. on route we bump into a few of the locals. but please have a mail in october not lots of flipping the our case in some ways do not less well and- it's part of the community from those of the spark. the big me own presence more birds rodents and insects that thrive in healthy grass and- please stand takes me to the edge of the park woody borders on a working ranch. the difference in the grass on either side striking. here is a good example of what happened in one place where you

remove their livestock. and one place where the land known as the site to put more lifestyle then they land is able to support a so food. so the consequences that you lost the visitation and you see the composition of the plant these defense so if you have life still been mentally eating the grass. they don't have the chance to release the seeds and very cool very very slow there are some consequence like a roaster that. is very hard to address and it will take over and asked him to read to be really recall for. on the eastern edge of the park easton and the team have established a breeding center for any danger relative of the ostrich called the darwin's ria. young ria artificially incubated brought here to acclimatize before being released. re us they are strongly associated with their-

but the going in a state with the grass land so i grassland without the re yes he's not complete. and demand for both of the center. is that the captive population is providing in the p. those intimate things for the white population they may need to hear. was that the white population was so. dining say less than twenty but- the white population of reagh west estimated by hunting and the destruction of their hobby that but is now slowly growing and successfully dispersing. well here are from up there via that have been released. then you'll see that theres a line of fans right now we are removing it and daddy prove. the clinic baby at the off the areas that have been released. beat me. with a wide area. we are now in effect generation and we are planning to keep this program running in the next three five years. when we estimate that we can reach. a population of

about a hundred bird saying the white. those tiny the growing real population we turn help sustain their only natural predator and the species i'm most excited to see. they use the king of patagonia diploma. i've come to meet i see listed below via a former heard their ample mahanta. to the main event. he and others in the area used to keep over ten full months each winter to protect their communities clocks. for instance. limited of. good way to do this in a you could. the kid the bottle with a long ago if he took on a month on the phone yeah. and does it sitting at the end of mobile. language i mean. i would only the tool name but not both yet to think

when anybody and i'm- a see you know works with a wide lead warden and he's departs racing and pull my tracking experts. if anyone can find the a full month it's him. yeah i can sell it but after that is blue. like the one on a low for the mentally ill. and that's the kind of. you can go on forever may have on a little longer time i'm going to waive. not only can you give us room for my- i mean more maybe. in a telegraph and i said look i let us here. well yeah. i'm worried about how to set the new growth. thank you bye. memento. we don't need any money to buy the whole room. yeah right yeah. to see the knowledge this man half of the land. i can see there but he can distinguish upon what track anyway most

preferred to hunt at night on our chances of seeing one are very clean. so we're doing the next best thing setting a camera trap which are seated on the table used to monitor their activity. but a lot of one of the rest of the men. looking ahead what a credit. hi i see eight ten. over here at home where program. before the you'll both cut you're in jail. because the thirty seven cents. the send bait should grow into musky or is that another cut us being here. we're going to leave this camera type for a few days and see whether we get lucky. it may be hard to actually see a puma but for chris they return incredibly important. predators have been systematically persecuted for. decades and decades so their numbers get precariously low. every ecosystem has what's

called their apex species here in patagonia its fullness and if you take out the very top predator. everything cascades down from that and comes out of order. even though it's early here and the park in terms of re balancing we can see. some big changes. where there are water systems and grasslands are definitely coming back the number of homeless in the park and the numbers of one not because in the park fox's but the success comes when all of those species are truly back in a system that's functioning without human. intervention. as well as helping to clean air and water large expanses of forests and grasslands also naturally sequester carbon crucial way to mitigate climate change. these regenerating forests also play host to a tree to so rare it's almost

mythic any three heavily station could be the parts seem to be this challenge. two wide life rangers have promised to help me find it. what a. but i want to know yeah. the end of the land but i mean that any any and then it is backed up by the who. perfect. but then again one three yeah but overall author did i don't know but i wanted to get anyone i am not going. to give you. a lot. any thoughts on. the neal trucks were moving the year using tellement three. the something other techs radio frequencies emitted from corner some of the year. equitable friday okay thanks to a monumental sunndal anyone yeah both in the scene told for you already the entitlement. since a they're going no no i don't know if it'll say look and what time was he in. perfect okay then. and now and they look for

cydia must have none of it. yeah i think i have thirty across. yeah. they had a thought what is the okay yeah. how did the destruction and poaching how broad the win movie something's going to south indian dear to the brink of extinction. there are fewer than two thousand left in the why just 1% of their regional population all of them in chile and argentina. balance and do. but i had a call with a polish film but i have a cell of a relic containing of on the fence the man on the set a. thirty plus samantha they you he a monumental. they get henry menton is. comma for my little boy who can assist one. down in the nine and let him i linger

yeah in a quadrennial even at the eighteen it today miss he made them all up. thank. the customer may. out of an argument are gonna come. the senate. not gonna femina or yes again can. you know one of the very beginning. the nearly bites me back to his family home to meet his wife yeah. their family comes from a long line of coaches wrenching people found the cross but they go any where often fiercely proud of their way of life. many go to us in the nearby community of cochran c. conservation a threat to both their livelihoods on their call to. then you'd worked on the

old french assess shepherd for six years. before taking a job conserving wimbledon in the park that replaced it. there but i can dig cancel yeah we and iome full season though joe for confirming for medium in mono you know. one another with their kids gary jumped in as a set of. sending a distancia it on. demand when did they are doing to soon find out. you can in this is to sit in a gas is a regular thing that. when a vented that's only a single and then they get a- little more comfortable if i sell the game but. give us a full senate tens unit of us but. we can do any of them will a woman in in moon okay i'm we pull pull a formula. for avoiding a- legal within the

fifty. this is the wrenching also complained that pull must leave the park to keep their livestock. all sixteen people working on the ranch when it was closed where danny bill that the park eight of them a spark bar dance like than in. by twenty eighteen the parking floyd more than ninety people during high season. meanwhile two recent has created sustaible sourc of inco for local populations. this was truly an emblematic ranch so just the image of this region ships. when the land use chefs anthat was really hard on people which i completely understand i would hate to have this area of being a 100% tourism and culture would fracture. the structure of society would begin to fall apart and that's not what i'm interested in i'm interested in working ranches along side conservation areas so there is dignity and health on both sides. but when chris and doug started buying land look at grievances were just the beginning. some chilean stated with a us land grab a plot to

control the country's whether or even study society state. the dunk is also infuriated conservatives when they join the popular campaign to stop a giant dam project near the park. but their high profile role in the movement in which thousands took to the streets forcing the government to reject the project. one of the many of my readers across chile. one way they're fundacion hopes to contribute to local communities white also convincing them of the benefits of conservation through a free education program. cation officer caught him with the nice leading a school group from the nearby settlements of three kilo on more data on a two day trip. just yet they can't get a signal to. the musical the music thank you. they look it up by that musically selig is about. extension excellent next

as soon as you go north of it. welcome us as a cynic is someone. is the phone the then the internet the knee. yes on the little guy. in and out of the thirty addled ali is so if the minimum to see if you get the because if you can get i need you could tell it to me and then completed so kenny of an income. then okay come get it hello he got a calm for a meal they love that yes he is so is so how do we get them all with all the pull cord of a little guy soon on the net that you cook a- kilometer less and less often. settle it on a cell a glass that he and thank. is a local company i guess a lamentable professors. what could have been a good days and all colonial. manacor ab so what i'm what is sort of a credit for. an idea. what

troubles in online. sales here thanks a lot. the only full time monday. zero zero. yeah. i'm meeting up with that the check out counter top. we have heard that the poem has been spotted with the carcass of a when i go. on go to check it out. to get in a good indicator but if. okay intermountain former you'll get medicaid. check out for some charitable raman the. food at a ten thirty a talented eagleton. the for you have a little miniature poodle temperament. let me

think a lot of the kids. yeah the nickel for the room where the settlers at. is in the air. given a certain hey. jennifer hannah. where no dent internal severance himself enough. israeli plaza the sample by the letter can on a button. no luck this time but the cd on the team have used camera traps to the command over thirty five who must now recede into the park. with violence returning the donkeys foundation fuse ready to do what they have always done with their parks the native to the state. in at twenty eighteen signing ceremony with then press the and michelle bachelet resend it over these and another part worth a combined one million acres. it was billed as the biggest donation of private land to a state in history. the

chilean government also contributed nine million acres of their own. well this land now forms five new national parks and expand three there's an area three times bigger than yellowstone and yosemite combined. these also to head the naval the rudolph parts project scenic road one thousand seven hundred miles long connecting seventeen parks across chile boosting the economies of the community some root. right now the largest and other duties facilities are closing down until the handover process is complete. so the whole team. they're all saying goodbye to one another and it's not likely they'll be back next year so. yeah it's sad. less than four years after doug died in a kayaking accident scene their dream finally become a reality aesop on a moment. here is. the day that dog died he

was on a kayaking trip with our best friends and they got caught out in a severe or westerly wind they were getting pushed farther and farther out into the center of the like and so they decided to abandon the kayak and try to swim to shore. and it was just. too much the dog was in the water for over two and a half hours and they got him out he was helicoptered to the hospital and clay aiken. and somehow the word spread so fast that doug. had either died or was in trouble and as we drove to the hospital people were on. they're hard hats off and opening up. it was amazing i really thought. it was quite

extraordinary anyway we got to. way i can and died twenty minutes before so. soon after dogs deaths chile's national congress voted to make him an honorary chilean sea descent it was an official recognition both of the tompkins contribution to the country's natural heritage and of how much the public have come to embrace them. what a live. here's a guy who had no limitations in this line. you know you're so easily stopped by things that are difficult or seeminy impossible. he's. an example of twenty people yeah. i'll we leave behind a legacy of if you don't establish some sort of value system that awards peace between human and

non human world. i'll never get where we need to go. i'm using my final evening in the park to take a proper hike the only way to truly appreciate the spectacular plays. the sony hack into had the chance to be said one of the few remaining great wildernesses of the word. experience has shown me just how precious this ecosystems are and how easily they can destroy the human activity. lady that's also given me hope to see that these grasslands of forest have been revived to welcome back the amazing creatures that once called him íñíñq■x■x
