Abstract

Sarcoptic mange is a threat to bare-nosed wombats (Vombatus ursinus) in Australia and a major factorcontributing to the decline in populations of this species. It is caused by a mite, Sarcoptes scabiei, and ifuntreated can lead to severe irritation, blindness, starvation and eventual death. Our study aimed to estimateand compare the population numbers of bare-nosed wombats at three study sites, and to determine howrainfall, temperature and humidity influenced the incidence of sarcoptic mange in bare-nosed wombatpopulations. Macropod and rabbit abundance were also compared to wombat abundance and sarcopticmange prevalence at the three study sites. Across the study sites a total of 1655 bare-nosed wombats wereobserved. Sarcoptic mange prevalence was between 8.9% and 40.3% depending on location and year.Sarcoptic mange prevalence correlated to yearly rainfall, with a higher incidence of sarcoptic mangeoccurring in higher rainfall years. Further monitoring is required to ensure sarcoptic mange prevalence doesnot increase at the study sites. Increases in prevalence will likely lead to the extinction of small and isolatedpopulations in years with high rainfall.
