The Grey Fox is widespread in forest, woodland, brushland, shrubland, and rocky habitats in temperate and tropical regions of North America, and in northernmost montane regions of South America. There is no good evidence that Grey Fox numbers are increasing or decreasing in any part of their range. The species is not considered threatened at present.
|Range Description:||The Grey Fox ranges from the southern edge of central and eastern Canada, and Oregon, Nevada, Utah and Colorado in the United States south to northern Venezuela and Colombia; and from the Pacific coast of the United States to the Atlantic and Caribbean oceans. The species is not found in the northern Rocky Mountains of the United States, or in the Caribbean watersheds of Honduras, Nicaragua, Costa Rica and western Panama.|

|Population:||The species is common in occupied habitat, but appears to be restricted to locally dense habitats where it is not excluded by sympatric Coyotes (Canis latrans) and Bobcats (Lynx rufus) (Farias 2000b).|
|Habitat and Ecology:||In eastern North America, the Grey Fox is most closely associated with deciduous/southern pine forests interspersed with some old fields and scrubby woodlands (Hall 1981). In western North America, it is commonly found in mixed agricultural/woodland/chaparral/riparian landscapes and shrub habitats. The species occupies forested areas and thick brush habitats in Central America and forested montane habitats in South America (Eisenberg 1989). Grey Foxes occur in semi-arid areas of the southwestern USA and northern Mexico where cover is sufficient. They appear to do well on the margins of some urban areas (Harrison 1997).|
Habitat loss, fragmentation, and degradation, may be particularly problematic in regions where human numbers are increasing rapidly and important habitat is converted for agricultural, industrial, and urban uses.
Because of its relatively lower fur quality compared with other species, commercial use of the Grey Fox is somewhat limited. However, 90,604 skins were taken in the United States during the 1991 and 1992 season (Linscombe 1994). In Mexico, Grey Foxes are frequently sold illegally as pets (R. List pers. comm.).
Not listed in the CITES Appendices. The Grey Fox is legally protected as a harvested species in Canada and the United States (Fritzell 1987).
Grey Foxes occur in numerous protected areas throughout their range, such as Big Bend NP, San Joaquin National Wildlife Refuge, Rocky Mountain NP and Everglades and Dry Tortugas NP, and Adirondack NP.
A number of foxes are held in captivity, although there may be more in the hands of private collections/individuals who do not report to ISIS. Grey Foxes appear to fare well in captivity and commonly are on display at zoos and wildlife farms.
Gaps in knowledge:
Because of the relatively high abundance and low economic value of Grey Foxes, surprisingly little research has been conducted on this species. Basic ecological and demographic information is needed for each of the major habitats occupied by Grey Foxes. Also, data on the response of Grey Foxes to human-altered landscapes (e.g., urban environments) is needed. No region-wide or range-wide population estimate has been produced. Furthermore, extremely little is known about the status and ecology of Grey Foxes outside of the USA and Canada. The effects of Grey Foxes on populations of smaller vertebrates, especially in urban and suburban settings without larger predators, may be important.
