澳大利亚环境部把东部沿海多地的树袋熊保护级别从“易危”升为“濒危”。树袋熊从不受保护到成为易危物种再到濒危物种仅仅用了10 年左右的时间，因此，保护树袋熊势在必行。

Koalas were declared to be endangered in eastern Australia. More koalas are dying from disease, lost habitat and other threats.

Earlier, koalas had been considered as a vulnerable species (易危物种). Federal Environment Ministry lowered their conservation status on the country's east coast in Queensland, New South Wales and the Australian Capital Territory.However,the government's Threatened Species Scientific Committee recommended that changes should be made because many koalas in Australia suffer from chlamydia,a kind of disease that can cause blindness or infections.

Australia has lost about 30 percent of its koalas in the past three years.In 2020,an investigation warned that the species might become extinct before 2050 without immediate help.The number of koalas in Queensland has fallen by half since 2001 because of lack of water,fires and deforestation.Also,some are killed in attacks by dogs,or hit by cars.

“Koalas have gone from no-listing to vulnerable to endangered within a decade. That is a shockingly fast decline,”said Stuart Blanch, who is a conservation scientist with the World Wildlife Fund-Australia. He added that koalas will go extinct if new laws are not passed to protect forests.

The Australian Koala Foundation estimates that there are less than 100,000 koalas left in the wild or there may be as few as 43,000.The summer forest fires in 2019 and 2020 killed at least 6,400 koalas.Rescue workers tried hard to save them and treat their injuries.“There have been many pressures on the koala. The big fires, of course, were a tipping point. We know the koala is vulnerable to climate changes and diseases,”said a government official in Australia. She said the government is working to protect the animal and now vaccines are being given to koalas to prevent and treat chlamydia, and drones are being used to study them and rebuild their habitat.
