As of my last knowledge update in January 2022, the population of Tasmanian devils in the wild had declined significantly due to the impact of Devil Facial Tumour Disease (DFTD) and other threats. The disease has had a devastating effect on the devil population in their native habitat of Tasmania, Australia.
Efforts were being made to manage and conserve the population, including the establishment of disease-free insurance populations on the Australian mainland and in sanctuaries. Some areas in Tasmania were showing signs of population recovery, but the numbers were still relatively low compared to historical levels.
The population of Tasmanian devils in the wild can vary by location, and it's essential to note that my information is not up to date. I recommend checking with the latest sources and conservation organizations for the most current population figures and conservation efforts for Tasmanian devils in the wild. Conservation efforts and population data can change over time, and it's important to stay informed about the latest developments in their conservation status.
