Brush-tailed Rock-wallaby

        The Moora Creek colony population has been stable for almost a year (touch wood), the last mortality was in April last year. The population is currently 7 animals. Images are retrieved weekly from a series of remote cameras that have been deployed through the release site. Image attached, female 82 who is our longest surviving wallaby (close to 8 years old!). Individual wallabies can be identified from the colour or pattern of their radio-tracking collar antennae and ear-tag.

 Quoll

      Further remote camera images have been obtained of a spotted-tail quoll. The quoll has now been detected on four separate occasions, all at the Brush-tailed Rock-wallaby colony location. Parks Victoria is attempting to gain a hair-follicle sample from the quoll in order to determine where it has come from. To achieve this rangers have established cage-traps adjacent to the rock-wallaby colony and will trap periodically, will establish hair-tubes within the rock-wallaby colony at locations where the quoll has been detected, and will work with the Otway Dog Conservation program (http://www.conservationecologycentre.org/our-work/conservation-dogs/) to see if their specially trained dogs can sniff out a quoll scat.

 Grampians Ark fox monitoring

        Ranger Ben Holmes has been busy setting up close to 160 remote camera locations within the Victoria Valley and upper Wannon River area in order gain a precise understanding of the Grampians fox populations. This project is a research partnership between Parks Victoria and the Arthur Rhyler Institute for Environmental Research. While reviewing images from the cameras Ben has observed a myriad of animals, including a Koala (image attached), southern brown bandicoots and even more exciting, a Long-nosed Potoroo. In the last 10 years potoroos are only known from 2 locations within the Grampians, both of which are long-unburnt. This recent find is exciting because the potoroo was detected in a new location that is within the Mt Lubra fire-scar, just east of Moora Moora Reservoir.
