Australia has one of the worst mammal extinction rates on Earth.
In this ABC article, Aussie Ark President Tim Faulkner said Australia has one of the worst mammal extinction rates on Earth.
“They've [Platypuses] been in this constant east coast temperate environment, largely unchanged, for millions of years. In our region, they're all dead, they're gone — I can’t find them” he said.
The problem is that the Platypus is relatively hard to find, and a lack of long-term monitoring means that the decline of the Platypus has been largely unnoticed… until now. In NSW, the number of Platypus observations has declined by around 32 per cent in the last 30 years. That’s why researchers at UNSW, along with the Australian Conservation Foundation, WWF Australia and Humane Society International Australia have pushed to list the Platypus as a ’threatened’ species.
