A widespread effort to save wombats with deadly mange disease at a national park in Tasmania’s north has been unsuccessful, according to researchers from the University of Tasmania.

In a paper published today in the Journal of Applied Ecology, scientists detail the results of a treatment regime they conducted in Narawntapu National Park, revealing that while the wombat’s condition improved during treatment, all of the animals have since died from the disease.

A sarcoptic mange outbreak began in the park in 2010, depleting the population by more than 90 per cent.
