We Found 29 Threatened Species Are Back from the Brink in Australia. Here’s How

Post by misbahulalam »

Australia’s natural world is in deep trouble. Many of our species are getting rarer. Some are now perilously close to extinction, while entire ecosystems face collapse. Sudden biodiversity loss in events such as the Black Summer wildfires happen against a backdrop of decline due to land clearing, introduced species and other pervasive threats. For example, Australia’s threatened bird species declined in abundance by an average of 44% from 2000 to 2016. It is easy to lose heart – to be numbed by despair for an ever-diminishing natural world, or to dismiss our environmental laws and management as useless and broken. But we have 29 reasons not to give up hope.

Our new research has found 15 threatened mammal, eight bird, four frog, one reptile and one fish species have recovered enough that they no longer meet the criteria for listing as threatened. Our assessments Country Email List were based on scrutiny of the latest data on population size and distributions – a review process that the government doesn’t routinely do. These recoveries stem largely from years of collaborative conservation between government agencies, conservation organisations, First Nations groups and individuals. How have these these species been brought back? For almost all of the recovering mammals, the key threat pushing them towards extinction has been predation by feral cats and foxes.

Introduced predators are the primary reason for Australia’s unenviable record for the world’s most mammal extinctions, with 33 species gone forever. Because it’s impossible to eradicate the millions of cats and foxes across Australia, recovery of these threatened mammals has largely relied on a network of havens – islands and mainland exclosures that fence out predators. Once cats and foxes are excluded or eradicated, threatened mammals can bounce back. Read more: The future is fenced for Australian animals Take the burrowing bettong. If you’re like most Australians, you’ve never seen one of these. Think of it like a quokka that can burrow.
