Additionally, red foxes have been expanding into the Arctic due to expanded food resources and greater habitability due to climate change. In southern Wisconsin for example, its most popular prey are cottontail rabbits (Vertebrate Collection – The Department of Biology, n.d.). The red fox is flexible in its diet and is known to consume other mammals, birds, fish, reptiles, invertebrates, and plants.

Lower altitudes are popular between the warm and cold seasons, and throughout other months, the higher altitudes are preferred (Cagnacci et al. Altitude also has an effect on where this species lives. “ Red fox ( Vulpes vulpes) range map” by Zoologist, CC BY-SA 3.0įor most of the year, the red fox can be found in conifer woods with their ideal habitat changing throughout the year depending on the weather. Red fox range, where green = native, purple = introduced, orange = presence uncertain. Based on historical data, we can expect the red fox to continue to expand north and east in the future (Allen and Sargeant 1993).įigure 2. It is also worth noting that the species has been extirpated in the Republic of Korea due to their population control policies (Canid Specialist Group n.d.). This vast population range can be seen in figure 2 below. The few places that this species is not found in are Iceland, the Arctic Islands, parts of Siberia, most of Africa, and Central/South America. 2012), and Australian and Tasmanian populations are entirely introduced (Hoffmann and Sillero-Zubiri 2016). European populations of red foxes are natural residents of the area (Hoffmann and Sillero-Zubiri 2016), but North American populations are a mix of residents and introduced individuals brought in for fox hunting in the 17th century (Statham et. In total, their range covers almost 70 million km2, making them the widest-distributed members of the order carnivora in the world (Hoffmann and Sillero-Zubiri 2016). North American populations stretching across most of the eastern contiguous United States and all of Canada and Alaska, as well as populations in Australia and Tasmania (Hoffmann and Sillero-Zubiri 2016). Red foxes are extremely abundant, with populations ranging across all of Europe and large portions of Asia. The exact number of red foxes is unknown because of their broad distribution around the world. fulvus) observed in Algonquin Provincial Park, Ontario on January 2017.” by Joanne Redwood, CC0 1.0. “ Eastern American Red Fox ( Vulpes vulpes ssp.

Red foxes are highly effective predators and excel in a wide range of ecosystems. In contrast to the other species in this book, the red fox has a very healthy population size and is actually driving the extinction of other species. However, the red fox plays an important and unique role in ecosystems across the world. The red fox ( Vulpes vulpes) is one of those creatures so common that people rarely give any thought to it.
