Abstract

Bare-nosed wombats (Vombatus ursinus) are an often important south-east Australian agricultural riparian species that may improve riparian landscape heterogeneity via their burrowing activity. At the same time they are often accused of causing soil erosion. As populations of wombats in other landscapes are under threat due to habitat disturbance, road mortality and disease, knowledge of the factors determining their use of riparian systems are important for their conservation and management. Since the European colonisation of Australia, riparian areas have been utilised by domestic cattle (Bos taurus), usually resulting in a decline in biodiversity. Camera-trap data was used to investigate the habitat use by wombats and cattle in remnant Eastern Riverine Forests. A total of 664 detections of animals from 13 species were made over the entire riparian-zone survey. Wombats were the most detected species, followed by cattle, then foxes and cats. Wombat and cattle activity varied significantly through the diurnal cycle, with wombats active from 1900 to 0700 hours and cattle active from 0700 to 1900 hours. There were no seasonal effects relating to the detection of either species. Feral species such as foxes, cats and rabbits were more frequently detected at sites highly disturbed by cattle. Results of this study illustrate the potential of camera-trapping for modelling habitat use by wombats and cattle and providing guidelines for the management of feral animals in remnant agricultural riparian habitats.
