profiteers and talk with people experiencing a changing environment fragile the ice disappears earlier and it keeps retreating our future depends on what happens here the in northern lights life within the arctic circle starts december 21st all g.w. a repeat of the. december 29 teams strains bushfires spreading across bigger and biggest waves

so planned for wildlife researcher kelly it is becoming clear just how perilous the situation is. she decides to evacuate the 12 koala bears that she has been studying for years before the flames reach the blue mountains it is the 1st time that she has been forced to take this kind of action. you know i'd be all over the floor. with a small group of experts on phone tears she manages to save a small but still significant number of koalas that survival. it's important for

the conservation of the species. hundreds of thousands of all the animals. in immediate danger. area. where they're at yeah yeah. yeah. yeah yeah so.

i asked. one month after the evacuation of the koala bass we meet up with kelly again on the edge of the national park where she wants. she still unable to visit the most heavily bound area for safety reasons. their guy back then blazes was still raging in 2 australian states and had already destroyed 80 percent of the blue mountains national park the park is part of a unesco world heritage area and home to the country's most genetically diverse population of koalas. pretty heartbreaking to say especially once you get to know

koalas you know we give them names who go volunteers that come out to help track them where we had to we were really lucky that we got in and got some out before the fires that had radio collars on them and say all but 2 we've got one koala on the on burnt side we hope are still here and then one that we had to lay down in the area he was too far and it would be an all day just to get one and we got 4 or 5 that day so we really came to get it and see how he's doing but knowing there's so many through here and now it's such an important population that's nationally significant it's yet been utterly heartbreaking to watch it happen. the research is real mission is to devise strategies to help protect the species from possible extinction but instead she finds herself giving 1st aid to animals that have escaped the flames. yeah. down

a bit i think what's happening is that working can stations with water and food are now essential for the d. hydrated injured marsupial survival spin isn't it. we can also put a rope on the bottom to guide it as it goes out. when i'm going to check. any. more territory. that the colors come or. go don't really want to hear that.

we had a story of hope here in the mountains where finding a lot of koalas where we didn't expect there were young and growing populations and their own in in a protected area that's protected from habitat loss and now we've lost 4 for the 5 populations that we've been studying have been impacted by. killing came to us i think it was around the 23rd of december. it was the day the township of the open which is about a 15 minute draw from he was impacted by severe far conditions they lost houses the conditions were terrible. she was found by the far far as at about midnight in an area of force that had been completely burnt out in mazing thing about her is that

coming out of that area she has not been. morgan film part has been working closely with kelly lead for years he has even named one of the bands in his cat kelly in how ana carried a koala has recovered from the problems caused by smoke inhalation bans both kelli and her companion marine are suffering from a bacterial infection that focal wanders can end in death it's a real privilege to have these animals come in and stay with us it's a lot of stress as a care because you want to help everyone that you can unfortunately we can't always help these animals to the point that they can be released sometimes we had 2 injured although to sick obviously the best part of doing this is that you get to let them go and take them back with i should be because this isn't where they should be back out in the wall is where those guys should be to go out and make more more koalas. you know he's years of looking after wild animals

morgan has never had so much to do one of the main challenges is finding the right eucalyptus leaves for them to eat. he says he is distraught and disappointed by the way australian politicians have failed to acknowledge the dangers of climate change for so many years fire is not near as tried by any stretch but certainly the skyll and the intensity of the far as that we're saying now is something i don't think any of us have signed the tractors will say the strike is always advise and unarguably that's correct but not like this it's either warming just not used to getting the scale of animals that we've got coming in right now as a result of these far as that's a national treasure or international tragedy and these animals don't just belong to us as trying to belong to the world. and just the scale and the loss is

an imagined will. have they're going to bounce back and it's not obviously it's not just the koalas it's always try and wildlife affected here and the bush as well. the bush fires raged for 240 days destroying more than 12000000 hectares of bush and releasing 400000000 tonnes of carbon dioxide into the. wildfires are a seasonal occurrence you know strongly and global warming has extended those seasons and made the blazes more severe. 3 years australia has been experiencing extremely homes and dry summers.

1000000000 animals are estimated to have died in last summer's mines according to experts it's a figure that has shocked the world. it was one of the most destructive environmental catastrophes of our times. an army of volunteers vets and scientists joined together to help in an incredible act of solidarity. the.

australia was caught unprepared and was confronted with its own vulnerability it became apparent that it did not have enough resources and effective strategies to protect its unique ecosystems the government has listed 113-1000 species that need emergency intervention to ensure that survival after the devastating fires. could come get a little. bit out of the way but i've. never met with the mayor no the quicker us your animals came to us than expected i thought that many died in the

flames or had to be put to sleep because they couldn't be saved. when the any money being going to. happen if you get if we consider whether treatment is worthwhile or not and unfortunately many were not to be saved. we decided to put to sleep animals with more than 20 percent burns mistreatment in those cases has little chance of success or is very protracted. for maybe a place at an. animals have in behavior to protect themselves and fires they follow nature's lessons in the event of danger or that the one bats generally hide under ground up and koalas climb up trees higher and higher when they become a normal fire is usually burn in the middle section and travel rapidly. eucalyptus trees are full of oil and the fire moves on and the treetops remain intact and when the creatures are badly affected by smoke inhalation they can survive with that a look this year the fires were so ferocious that the trees burned in their entirety of that when the koalas were roasted alive in the treetops on the.

italian vat neurons no cross is director of the university of sydney's avian reptile and exotic pets hospital which provides canta wildlife. he's one of the few people able to treat the little researched koalas today he is looking after a fonzie a koala who was found catching on to a tree in a river although he has no obvious severe injuries the creature still isn't back on its feet. with your terrible. we're going to take some of a cerebral spinal fluid and send it to a lab for testing. we want to know whether it contains inflammatory cells or bacteria which would cause and suffer lidice or meningitis if plague in a way because in that case we will of course have to treat the animal differently with a bit of a bit of. a lease to the bushfires have given scientists an

opportunity to gather useful data and the global headlines have forced the all foreigners to provide funds to help save wildlife yet silicosis if everything goes well it will hopefully develop new strategies now that we can use to help australian wildlife in future fires on its own with the not just to save animals directly but also for example by issuing guidelines to prevent those kinds of fires every year and to know how to respond when the fires become threatening that's just as important as the treatment of the animals themselves and that prevention is better than a cure but any of them in your head that. can use koalas have been living in sydney's taronga zoo since their evacuation there they are patiently awaiting their return to the wild. they're feeling a lot better and while a climatized and no longer dehydrated. thank you.

that we've just gone through and removed a few of their branches that were fed out yesterday what that they are the lucky ones and they are now in good hands nick performance has been looking after. for 20 years now but even so particular responsibility in this situation 1st few days no doubt you know there was some settling in stress that they koalas endured they were captured from very tall trees in the wall and put into little carry crates and then transported a few hours by car so all of that was foreign to them so of course they were exhibiting some stress what we've seen in those few weeks that have unfolded since is that they're quite comfortable animals now would change their husbandry practices to be is mainly disturbing and so we only come here sit on of the day so the animals become accustomed to that we're seeing demonstrate normal behavior is any good genetic population that we can hold on to is just being made so much more

vital. at least 8000 koalas dying in the state of new south wales party desires to mated that the country's entire population of the creatures has been decimated. their numbers were already in decline before the bushfires because of endemic disease the destruction of their habitats by uncontrolled logging and illegal wildlife trafficking. while as a species was in their millions european settlement so we're talking only just over 200 years and now we're a seeing such a huge population of quine that we're now within estimates of 830-0000 now obviously significantly less than that due to the recent fires so when you consider such a small amount to what otherwise the habitat could occupy they are they are in dire straits like there are species in the climate and certainly you know worthy is

being listed is a threatened species it's taken a very catastrophic event like these large fires for people to actually realise the situation that i was watching. if there will be this way. after months of finance the deluge of rain followed followed only partial relief. the worst france in 3 decades brought new problems to the beleaguered country. where the events of this kind could become the new normal. in quick succession australia found its own going from one extreme to another for

signs of an ecosystem that has been thrown off balance. which could recover but only stone age. in the midst of the janssen destruction the sun signs of life and knew how. to write. they were doing a couple different things basically this is to inform us putting our koalas back the ones we took out the patrol that so we're trying to work out if we need to put them back in the un burnside or if we can put them back in this low intensity band section where we got them from so they can be mighty bouncing back so i will be

going behind doing scat surveys and looking at how many sketches we find of the different quality vegetation and you guys have a during a search and rescue lion looking out for koalas so and if we find fresh scat we'll call you in to help go spotting for the actual koala that has the. in the group and so i would just have to stay in a tight group today announced that rescue alliance i was at radio but they think if yes did i well i would just thank god and all day it has been 3 months since the coal miners were evacuated from the blue mountains and now it is possible for kelly to send forth again but in certain areas of the national long. ok. let's go 1st because i get up early for what is called the smog is one of the dogs on the frontline of the koala search and rescue mission he can detect by smell things that we cannot see and that makes him indispensable worth much if not.

more. so he's finding some really small fragments lately. that you know of a half one saved their life fairly very much year old dried yet so that's half a dried quality that is also an old one so probably pray fire right up to my crotch like. all my life. it's yeah that one good dope it. fits him for a smudge. kid that old soon a bit of green in there. so. maybe waco too.

we have. heard since the right yeah more recent and so here we've got surviving koalas so it is finding older deposits at this site where we know those quotes have been through more recently so probably in a week or 2 so indicates the surviving animals here which is great i k moving. the discovery of the fresh promptings motivates the volunteers to comb the bush for commons. the excursion is also intended to us sas whether there is a now foliage to nourish the animals in the wild all of this information helps the researchers to map the scorched zone and compare the data with that gathered before the bushfires it helps them gain a clearer picture of the blazers impact. it's hard to determine how many animals

remain in the area but unless 100 tanks from is taken the beloved koala could disappear by the year 2050. their 3rd. world. war. or 35 forever. well spotted. this hidden by the canopy out there. and over. yeah so he's got a little dot mark on the chest there. so you can say he's a male and generally looks alright but is in good condition no signs of any injuries. so we will leave him in peace. healthy look and go out to have a let me straight up. so this is what we call

a non-college call on tags so it's a new koala one we haven't same before because if we took the most they out before the file data got 2 animals in here that do have tags on at the moment so most of that i'm going to find will be new we know only when we write a track we do find new animals every now and then because we know there's a pretty good population in here but we would also expect some might have moved out from the fire front up into this area as well so whether this is a resident or a koala that moved in we are not sure. how cali this is just the beginning of a painstaking repopulation process one requiring a lot of time and a lot of energy got to get probably one more wake of imagery satellite imagery to look at chlorophyll content and just check we have i've got exact locations of where we took them from so we can see if that where we took them from is a good golly that it is good moisture content and good canopy made for them and in that case of put them straight back so we got them from for some of them we might choose to put them if they came from really that hit patch we're much used to put

them back on the other side of the road nearby so it's just coming down to those details now of exactly when to put them back 2 months after our 1st visit we meet morgan again it is stopped raining the bushfires have been extinguished and walk is proceeding so the stuff is already as you feel it as you know has a 3rd koala in his calf so when he took him in 7 weeks ago he was a death's door the animal has recovered quickly and is now ready to be released into the wild again unlike kelly and marie who we met back in january. think it's starting to rain and then something happens to the girl that had some recent issues with skin problems through what we think is in this station of ticks that the had after all the rain events that happened i don't know whether it's correlated with this explosion of ticks. neither of them are sick comedia.

and by threading really well the getting all to white little marine he has gained a key ally in the last sort of 4 weeks and the other one's going about half of that it is putting on a little while and otherwise there'd be 3 we already today relates. more confines to camp for the daddy and disinfect cage every 3 days to find the tikkun fascination that he's not 99 cats in town returning the commodities to the habitat is a process that needs patients and sound preparation. part of the protocol is the quality get any tag and each year when recalled the color of the tag and the number and they also get a mock roach it inserted. in the shell the blood and that then and isles off that if this animal gets sick again or gets injured and comes into chaos then we know who she is and more who the medical history has day.

so i will be looking at a lace another 4 weeks in kate to treat this skin condition now and that's providing it responds to the treatment that we're giving. or it's ok and we're going to catch it i think it's all right. you know. it's a fade. but with animals like this unexpected things can happen and that sort of blows out in the tom of these animals staying careful and you cannot be taught and for taking but you got to you know he does once you commit to it you've got to keep going until the job's finished. and the our use of the won't. has become a symbol of both global fears and.

that is cali has caught we're about to lay sessions and trying to do for a few months now taking a back the right way we caught it from. him . commies return home without incident and she remains completely oblivious to her significance to research is struggling to save her species. the emergence of covert 19 rushes the article

almost to be released sooner than expected. this shows how connected on story years to that of our environment. and environment for which we are responsible. so i think again that's the way this is that now the sector commandments and we certainly haven't we obviously need biodiversity 70 percent of our medicines come from nature in a way highly dependent on it whether we realize it or not say i'm hoping that the tide changes and we do a mall before it really impacts us more than it has i mean this was a big impact for a stray as most people were affected by the pfizer knew someone who was affected by the fires say now's a good time to change that and i think a lot of us will be pushing that.
