The red fox Vulpes vulpes had a population of 600,000 in Germany as of 2001. This increase from the former count of 250,000 is attributed to successful measures against rabies in Europe in the late 1990s and early 2000s.
The red fox thrives in varied climates and environments, allowing it to retain a high population in many parts of the world. It lives well in tundra, desert and forest biomes as well as metropolitan and city areas. In Australia, its resilience in city populations has necessitated population control measures, as the fox is considered an invasive species and a threat to the country's natural wildlife.
