WESTERN ringtail possums are critically endangered and wildlife carers in the region are urging residents to help protect the species.
There are three clusters of ringtail possums south of Mandurah, from Old Coast Road, Melros, Florida, Bouvard and to Herron.
Fauna relocator Alllison Dixon said one of the major concerns with the species was predation by the south-west carpet python.
“Then there is, of course, clearing of bushland for subdivision, shopping centres, schools… the list is a very long one,” she said.
“This means possums have to move out of the area, completely, causing local extinction of all fauna from the area.
“The clearing generally leaves the area barren but ready for houses to be built.
“This means more traffic and possums could be killed or injured trying to move to another area. “This unfortunately will continue.”
Ms Dixon said injured or dead female possums could have an infant in their pouch.
For injured possums call 0467 874 580 or the Wildcare Helpline on 9474 9055.
