the schools we say they're never getting up every weekend on the w, the in the region, either side of the french, german border, one of your some rare stand them as being re introduced the european her internal gifts can be done, re introducing them. it gives us hope that we can save a major part of what plans, biodiversity come on, you can do it just a bit further. there you go. you have a ton. turtles can live to be 100 years old. could this one survive that long?
4:31 am
what chances does it have in this landscape? the beaver has been driving since it too was reintroduced in the region. some see the animals return as a success. others as a nuisance. despite them being strictly protected, some beaver's meat. tragic in the colonial se. literally those, but if it causes any damage, it has to go to sometimes the beaver is lucky though, and just brought to new territory the so by ologist kathleen tyson from the thinking back society in frankfort.
4:32 am
and john eve, george from strasbourg, beth carryall. multi disciplinary institute are heading a german french re introduction project. they've already released over $650.00 european pon turtles, at various sites along the upper ryan river. the turtles are regularly recaptured and their development documented the today. the do always working on the german side. this is our research so i can know people are coming up. there are around $150.00 titles in this whole area. let's see how many we find this week. you'll see the, the area includes old branches of the rhine river that have been spared from being
4:33 am
straightened or drained. the landscapes like these are becoming increasingly rare. let's see through it now is easy to concern you. i've lived in the countryside since i was young. i used to go fishing with my grandfather to create and they got used to nature in rainy weather. i have a crew back then. the forest was a very exciting discovery for me. nowadays, i often go there to run sick when you see what helps to escape the heck the ice of daily life could cd of a wheel. around 90 percent of the european wetlands have disappeared since 18th century. the project also aims to raise awareness that the turtles habitat plays a crucial role for sealants to lead me quickly. since you can tell me the present postpone. so, you know, so my plans are among the most important to ecosystems on national, their vast, fresh water risk. of course, we all know about the lack of water as habitats they produce and men spy on us
4:34 am
under home to incredible bio diversity. the new smyrna, you know, when we've waited far too long and done nothing worse, we've destroyed the wetlands and you have now it's time to reverse that and restore them. they have to con turtles are migratory. they require large, interconnected wetlands to enable their movement between france and germany. additional small ponds have been created. these are known as stepping stone habitats. however, a new issue has arisen in the pots likely released from a private aquarium and a misguided active compassion. the north american calico crayfish so look who's coming with the thick gilbert spic is a local engler. he also regularly tends to the ponds infested by the invasive crayfish lion. hello. hello, kaliko crayfish,
4:35 am
reproduced alarmingly quickly and they've eaten everything. the water has stagnated . it's one of these used to be beautiful bio tops now it's just a watering hole. buffalo wild stick nose amateur releases of animals are becoming and never more frequent problem to see what's in your trend . the artificially created ponds come with their own downside because a couple of 100 fish with land and water is with fish and other crayfish predators . they don't over populate something that the bigger fish keep them in check. but here there are non tripling. maybe we should consider introducing some human appliances. it's a switch takes the pragmatic approach to the crayfish, the catches. indeed i ma, well, it's wrong to kill animals and throw them away. and they actually taste really good deal to go see a good in the super than north of you to had speak system. i think it's great that
4:36 am
people like missed it. so they could go to the efforts of catching crace ation eating limit home offices as a scientist though, my take is to, with pushing this as a marketing opportunity. moulton, plenty of people would gladly, ex loyce, it for profit, and that's not the point. lucky. okay, mr. take is doing that. he's taking a sustainable approach to keeping the population in which it can toilets, the hype. so how does this for, you know, set up a sheet. i built the turtle at the quarry pond, the m m, as i mentioned in the, i'm not sure what kind of the sign of this is showing it looks to be with climate change. more and more exotic animals are surviving. europe's increasingly mild winter's household, pets, like red eared side or turtles are often released from the farm. sometimes from the shell shape you can already tell it is not a native channel. it's likely another unloved abandoned bat. just in a po is fis, competitions is, is there a big problem being, but yeah, this one, i'm sure that about when he drew this way, you,
4:37 am
the biologists have also captured images of a species that's been extinct along the upper ryan for nearly 200 years the beaver sleeva how many again, did you say we're happy to have be this here? it's great for the palm totals, because be back typically expanded as the wetland areas, naturally elsewhere. that's how it used to be. the beavers built the dams flooded areas and the water could spread out the beef as returning as a dream come true for what blond restoration the width rolled about it. why mountains to and not everyone is happy about the beaver's return, though a few years ago in bavaria, the position of beaver manager was created when conflicts arise. wildlife biologist, god shrug mediates and looks for appropriate solutions.
4:38 am
the beaver colony has made themselves a home in the lockbox stream. ever since roads and fields have regularly flooded. the damage has been so significant that local conservation authorities approved the removal of the dance and the fall that work was delayed. however, there were young beavers that needed to be cared for. first, you've been so if you go for the end of highlight beavers, but we live in a cultural landscape and beavers and humans have to co exist on this. they can just do what they want and stuff if it be for both of them and then floods. the basement was awesome. i wouldn't want to live there either. you all can host beavers are shy creatures becoming active at desk. up until the 19th century, fevers were hunted in new york. for a long time, they were nearly extinct. around 50 years ago, the 1st fevers from russia were re introduced into the bavarian danube region.
4:39 am
since then they've spread out with increasing periods of drought. people have come to appreciate their ability to build dams and hold back water since the last major tro year of my place and you know, think of, we've left the buford times in place with the farmers. notice that where the beaver's adult down there was still wondering the channels in the corn grew well, in places without them, it was dry. the corn growth on either side was stunted extra links. the stems only send to meet their stick with large gaps and these look that's when they realize the problem isn't with them itself. the problem is how high the dime is and as the whole damn was too high, the damage significant. as such, it was removed with care hard shops, approval now onto the next night near turning on the danube. a beaver has managed to florida meadow gear hodge rob is
4:40 am
on the site to assist. but the farmer who is affected hasn't shown up. instead, he's sent to representatives. the atmosphere is tense as they assess the damage. the farmer wanted to mo grosse for his animals, but he can't get to it because it's all. walter logged, his finished old chum. the grass is gone. mine does not just, we don't need to argue whether it's which or not the question is how great the damages let us know. we'll measure the area, but it won't be significant. your thumb greeting it, sleep in the season and the grass isn't the best quality. the farmers association provides charts to calculate the damage. april 10th of one percent of $200.00 tech tears. that's a back to euro soto stickly to euro. some damage caused by the beaver is he's outside. we haven't even spoken about the time who i need the site, the time spent is taken into account and the compensation calculations. but at least most not we go by the farmers associations rate and just doing this. i don't
4:41 am
want to hear that it's wrong. if you're not happy with the compensation log in and complain to them readings and as the result, the dam can stay back to the upper right today. kathleen ties singer and john if george are working on the french side, they are checking the turtle traps. they've set up, the stress is empty by checking regularly, they hope to keep tabs on how the tournaments are getting on the truck. yeah, they love this on u. s. this,
4:42 am
we check the number of the total. so we know when it was released and how old it is, then we measure and weigh it. then from the previous data, we can see how much it has grown and how long it's being out. tax. for ms. gross rate, we can tell whether it's doing well. well, no, say, well, the thing here. what i mean? yet, all their efforts to bring back european pond turtles will have been in the future . generations have no habitat, 1.9. that habitat however, has a p r problem that's easy to do on the job. so that, that's it. you will see if we've done studies on people's perceptions on these wetlands. they have the reservations because it's basically stagnant water, who they do with most of the new sex 7 on. that's what they think of is also suggesting the magic eagle, a physical solution just happens. it's the smell. i think that puts people off when done with costs. there are lots of in 6 to and some of the bites that cold come totals for a reason. they don't want to play water. they like swampy,
4:43 am
muddy spots with lots of nutrients in the woods and stuff. but wetlands benefit humans too. they act as water reservoirs reduced flooding store water during droughts and retain carbon onto the next trap. one of the reasons pon turtles nearly went extinct in this region, is that they used to be a popular food during lunch. but what poses a threat for them in the wild today? what happened? oh, well, there's a piece missing. well that's fresh, that's fresh. that is a freshman. i really think that was a taking the tale. yes. and last year we had the missing limbs. so when they go
4:44 am
with their fingers directly and just rips off when they also found in the trunk, then old acquaintance you haven't diet coke, they've just been on today yet. so it's kind of co creation. this one's already be nibbled on by the titles which is good to for this to come to to can help keep invasive the seems like the click a great session check and they also scabbing your dead animals on the central function of beacon system. does this make on speaker phone to one of their owns many other creatures here doing that that basically the health department has under 20 sites if this comes with and the project isn't just about reviving a last species. it's also about maintaining balance in the ecosystem, is that which requires ongoing care and monitoring this as soon as time if it's not enough to just renew the animal. so you have to prepare extensively in advance and then do
4:45 am
a lot to follow up with. like we are looking to the last of effects simply releasing a few typical sine wave doesn't help anyone else should quit analysis that's been checked for the record. the reintroduction project has been approved for an initial 4 years and has received 1000000 euros and e a research grant. and what it is that's being in a project is important that we can assess over the long term with as such, reintroduction and restoration assets all successful. last time. is it worth investing so much money? hands are sticking back to bavaria where the successful reintroduction of beavers hasn't been embraced by all at monford to fall those fish 5 and freeing. for instance, the animal is a frequent source of stress, even though it's a or before he set up a beaver trap at the edge of the reeds. is it for him to be so big clues because it's all right, so here's what i'd like you. once on him,
4:46 am
they get into the concrete basin which makes the fish panic. and then the beaver is usually by through the electric tables as they try to escape a system which in turn cuts power to the air ration pump, so they can produce without electricity. the fish will eventually die simply stedman. the hard shrub arrives with health to retrieve the beaver. many of the beavers captured in bavaria have been relocated to other countries. greece recently inquired about taking some, but for this fever, an offer of relocation has come too late. to smiled off and use his humor to try and refuse conflicts over the beavers. this, you'll like the article either is too excited to see you and knox, the cage over there. coney island isn't. it can live with those different causes on each homage. it has to go was a historic office to here. we catch a to 10 a year, and there are far more than that in this area. they're just dangerous. it's even
4:47 am
a threat to my livelihood. thanksgiving in this fever is out of luck. greece hasn't yet issued an import permit. forget hodge. bob has relocated other beavers to croatia. spain hungry, mongolia ending good. very good. follow up if i catch one and there's no permit, wait, no, it was greece. and even when we don't have the necessary authorization, then unfortunately this one is on a pass that doesn't lead to greece. it might lead to a live person a little bit, a very different one. this time the beaver manager can't relocate the animal to another habitat either. everything's already for the on the road with coffee, enticing or under colleague john e shores. they're hoping to witness young european pond turtles, patrick. but it's exciting, even as a scientist,
4:48 am
you didn't get to see something like this every day. but we're hoping that at some point the population will be self sustaining. fun. it's not a long time solution to keep reintroducing single animal. it's not that what are the survival chances for young turtles and the landscape so heavily shaped by human activity? draining wetlands and straightening river courses has destroyed much of their natural habitat. inspire the sea life aquarium is supporting the upper rind. reintroduction project. european pond turtles are bread and raised here. their aches are kept in this incubator. the biologists have arrived just in time. consider a quite a few touches o yoke, so i'm happy to look at the 2 actually. that's on as well
4:49 am
as on your she can determine the hatchlings sex solely based on the inter peters temperature settings. all these guys with the females varies by which is. yeah, that's it. from the population. they're hoping to get a turtle hatching on film. the footage will become part of their public outreach efforts. the biologist hope that these carriers manic animals can serve as in passengers for wetlands, reminding people how crucial these ecosystems are for the planet the right next door. the adult turtles are being fat. they can't to be called
4:50 am
vegetarians. these little creditors fight over the pieces of meat. they're given. impression. wow. they swallow enormous chunk toilet once snatched right out of the mouse. this is nash fives. like fascinating to he. how they easy to find over sewage. but that's something we never get to witness in the wilds. and obviously, if we go to work on them close by the regular feedings, you can still see how they interact. there's competition group, the ones come 1st and grab the larger pieces, the smaller ones wait for the turn to take what's left over infinity like will they find enough food and the wild? the biologists are the only ones hoping to see the turtles return to nature soon. the
4:51 am
240 kilometers, further east, the backyard pond. european pond turtles are living here too. right? trying to feed the basis of all these turtles belong to land floss. benjamin's r m, but as a fellow breeder and friend. today, utah sloss, who is serving the armored pond dwellers, earthworms, pieces of trout and ducks. hard to see alicia side, i've had some of these animals for 20 years now we see that it was attached to them with an i never give away any of the breeding animals months. that's what they're very dear to my heart. and i built a garden pond because gold fish are too boring for me. it has to be turtles. anguish when it's not feeding time, they're very shy. they only come out to bask in the sun when the coast is clear. how hard is it to breed them?
4:52 am
you know, basis european controls or under strict protection, but breeding them is easy. all right, let's take a little, actually on look at some of hatched. a female is $9.00 to $15.00 x, which you'd normally bury in the ground. for breeding though, an incubator is safer. some of most let's check. yeah. with the suck. yeah. so your sack is all used up. they're ready for the water. so this was a one here. think it has just 2 minutes ago. it still has a large, you tackled us of the breeders pride themselves on varying native species. speeches, us with a 30 this one right now when they're yolk sacks or used them, they're placed in the tank for young turtles, and soon they'll also be used to help restore presidents last wild life. the harvey tweets and tom white hurst contacted the german breeders online. they're aiming to re introduce the european pa, internal,
4:53 am
and it's native britain. the enroll on floss. baby turtles will play a role in this estimate. yes. hello. this is so my name is roland. yes, i have the a miss. yeah, yeah. this is mike harvey, tweets and tom white hurst have founded the conservation company secured sponsorship, and gotten the necessary permits. now they're close to making their dream come alive. it was founded by a half pace, really half a because i think that, you know, we've lost so many different species of wildlife but especially wrapped, tells them out vivian's. and it's great to see people who it just does that side to the impression that as myself, about these different species. but not only that, but you also want to help protect them. and that's great. all the turtles they
4:54 am
purchase are genetically tested and have all the necessary customs papers. benjamin has also brought hatch links for bridge. and how's the reintroduction go uh slowly is that also routine not on board. is that what um yes, this is the, this is the most problem. it's very difficult. a name at times it's, it's, it's hard on you because it takes a lot of energy to do. but i think the thing that we've got to do in a time way nature is going and going fast. we just got to keep pushing. and we do do not take no for an answer that. so we've got to do your work with them. in britain, european pond turtles have been extinct for several 100 years. harvey tweets is
4:55 am
convinced that these scavengers are vital for maintaining ecological balance and british waterways. especially in light of climate change. on the upper right, there's also costs for celebration. and you've got a really small one from last year. look. be very castle with this one on the deck line. they've discovered a one year old juvenile turtle in a trap. what makes it special? this turtle wasn't attached in an incubator. it emerged from its ex, here on the right all on its own. re for the 1st then you move, we need to find many more total stuff. this age. he's the phones of a whole. they need the chance to grow to about 8 to 10 centimeters. you can see that that, that size, they have far fewer predators. you don't look one clear to this, but this is a happy find. this isn't, it's a huge ray of hope for us that i work is truly making a difference in the turtle is released back at the same location where it was found
