The results of the 2024 Ringtail Tally have been finalised, with mixed results for the critically endangered marsupials. Participation in the citizen science project increased this year, with more than double the number of possum spotters taking their torches to the trees.
Coordinated by GeoCatch, the annual tally aims to improve knowledge and awareness of critically endangered western ringtail possums living in urban areas, with the information used to track population trends, future planning decisions, and focus conservation efforts.
Although participation rates were encouraging, total possum sightings were down from last year’s tally. Over the four weeks of the tally, 42 citizen scientists reported 651 possum sightings in their gardens and backyards across Busselton and Dunsborough, of which 121 were identified as different individuals. This was down from 149 individuals sighted in 2023.
Vasse Primary School and Busselton Senior High students studying Certificate 2 in Community Services were involved in the tally. Active Volunteering teacher Louise Mutch explained the positive outcomes for students and the local environment. “This is a beneficial program for our students to help look after our local wildlife and give back to our community. Last year, these students helped GeoCatch with planting and mulching trees on the foreshore that will eventually become possum habitat, so it is a great opportunity for our students to continue with volunteer work,” said Louise.
The ongoing research undertaken during the ringtail tally reveals some sobering stastics. From 2016 to 2023, there were 450 reported deaths, of which 64% were from road kills. Domestic dogs and cats were also a big contributor to ringtail deaths.
Nicole Lincoln, from GeoCatch, explained what pet owners can do to help the critically endangered species. “Backyard habitats are critical for the survival of the Western Ringtail Possum. Unfortunately, this is also where they come into contact with pet cats and dogs. Catios are a great way to let your cat enjoy the outdoors whilst keeping wildlife safe.
“If you have dogs, ensure that they are inside at night. You can also install possum bridges in your yard to allow possums to move from tree to tree, and there are some low-cost fence extensions available if your dog is jumping up on the fence to access a possum highway,” said Nicole.
Since its inception, the tally has expanded beyond the original Geographe Bay Catchment area. Nature Conservation Margaret River, Leschenault Catchment Council, and Wirambi Landcare now run the project with their local communities. South West NRM assists with coordination, making it a regional event.
This project is delivered by GeoCatch through funding from the Australian Government. The project is also supported by the Western Ringtail Action Group (WRAG) and City of Busselton.
