Tasmania's wombats appear to be winning the battle against a disease that almost wiped out the entire population in a northern national park.
Mange is still in the state's wombat populations but 90 per cent of the animals appear healthy, ongoing monitoring shows.
The disease, caused by parasitic mites, does not appear to be causing wombat numbers to decline, the Department of Primary Industries, Parks, Water and Environment says.
"Additionally, we haven't seen high prevalence of mange in populations, which has been linked with the population decline that has been observed at and around Narawntapu National Park," wildlife biologist Dr Rosemary Gales said today.
An outbreak of the disease that hit the national park in 2010 has been slowly wiping out the wombat population.
