Koala and other species are at great risk of dying out from climate change as the impacts of the effects of human activity on their habitats and habitats themselves change, according to new research.
Key points:Scientists say climate change could be driving the rise of koala and crocodile populationsThe study suggests that increasing the number of koalas on Australian land could help stop extinction in the wildThe study looked at data from 10 years worth of research to look at the effects that habitat change, climate change, and human activity have on the numbers of animals.
Researchers say they have evidence that increased numbers of koals, crocs and other mammals are becoming more abundant in the landscape.
Koalas and crocodiles are critically endangered in Australia due to habitat loss, predation and disease, and scientists are concerned that this will continue.
The study found that the number and abundance of koalingas and crocs is increasing.
“We know that koala numbers have been increasing since the 1970s, and they are increasing even more than crocs,” Dr David Wessel, from the University of New South Wales, said.
“But we also know that the croc population is decreasing, so this is likely to continue, because we have not been able to see the impact of climate change on crocs.”
The researchers also found that climate change has increased the number or abundance of kangaroos, which are the largest land animals.
“The increase in koalah numbers is likely due to changes in the koala habitat, but it is also due to increased habitat destruction by humans,” Dr Wessel said.
While there are some animals that can survive in higher areas, including humans, koaluses and crocodilians are likely to be at greater risk.
The research was conducted in collaboration with scientists from the National Parks Service and the Australian Wildlife Service.
