This December 2019 photo provided by Guy Ballard shows a male brush-tailed rock wallaby eating supplementary food researchers provided in the Oxley Wild Rivers National Park in New South Wales, Australia. Before this fire season, scientists estimated there were as few as 15,000 left in the wild. Now recent fires in a region already stricken by drought have burned through some of their last habitat, and the species is in jeopardy of disappearing, Ballard said.
