15035: Western Ringtail Possums: Filling the Gaps

    The Western Ringtail Possum (Psuedocheirus occidentalis) (WRP) is endemic to the south-west of Western Australia. Over recent history numbers have declined, and continue to do so due to habitat loss, degradation, fragmentation, predation by introduced predators (notably foxes and cats), increased resource competition (e.g. hollow competition), and have also been identified as a species likely to be impacted by climate change. Another increasing threat is unregulated relocation of rehabilitated animals (e.g. through introduction of disease). Due to historic decline, and continued threats, they are listed as Vulnerable under the Environmental Protection and Biodiversity Conservation Act 1999 (Federal), and have recently been upgraded to Endangered under the Wildlife Conservation Act 1950 (State).

    This project aims to determine the presence (or absence) of WRP within the Porongurup NP, and the area between the upper Kalgan River and Mt Manypeaks through systematic surveys, community outreach and input. Further aims include identifying the habitat types WRP's are observed in, as well as how they are using that habitat.

    Project activities include;

    • Systematic surveys, through spotlighting and using a thermal imager (including the recording of habitat WRP observed in) to be conducted seasonally
    • Camera trapping (baited)
    • Collection of community sightings
