Bare-nosed wombats are under threat from sarcoptic mange caused by the sarcoptic mange mite, Sarcoptes scabieii. Initially wombats suffer hair loss and become itchy, with the later stages of the disease leading to skin fissures, bacterial infections and ultimately death. Our study will identify how nutrition of free-ranging wombats is related to mange prevalence. By comparing the incidence and severity of sarcoptic mange, to the nutritional content of wombat dietary items and nutritional status.
