Ongoing monitoring of wild Tasmanian devils shows that overall population numbers are continuing to decline, due to the presence of devil facial tumour disease. Results of this research—conducted by the Save the Tasmanian Devil Program (STDP) in collaboration with staff from the Tasmanian Department of Primary Industries, Water and Environment (DPIPWE), San Diego Zoo Global, Toledo Zoo and the University of Tasmania—were published this month in the Journal of Applied Ecology, in a paper titled “Density Trends and Demographic Signals Uncover the Long-term Impact of Transmissible Cancer in Tasmanian Devils.”
