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.
A sarcoptic mange outbreak began in the park in 2010, depleting the population by more than 90 per cent.
Five months into the treatment regime in 2015, nearly all of the wombats showed no signs of mange, but the treatment wasn’t successful long term and the disease has now reduced the National Park's wombats to as few as three.
