Oregon is home to several fox species, which inhabit diverse landscapes from forests to deserts and suburban areas. Understanding these species, their habitats, and conservation status offers insight into the state’s wildlife.
Fox Species Found in Oregon
Oregon is home to three main fox species: the red fox, the gray fox, and the kit fox. The red fox (Vulpes vulpes) has an orange-red coat, black feet, and a white-tipped tail. Some red foxes also exhibit darker “cross” or “silver” phases. A red fox generally ranges from 10 to 15 pounds, with a body length of 20 to 25 inches.
The gray fox (Urocyon cinereoargenteus) has grizzled gray fur, a black stripe extending down its tail, and reddish or cinnamon-colored areas on its sides and neck. A unique adaptation of the gray fox is its ability to climb trees, an uncommon trait among canids, which it uses for foraging, resting, and escaping predators. Gray foxes are smaller than red foxes, weighing between 7 and 11 pounds and measuring 30 to 45 inches long, including their tail.
The kit fox (Vulpes macrotis) is the smallest canid in Oregon, weighing between 3.5 and 5.5 pounds. It has a sandy or grizzled brownish-gray coat that blends to light buff and white on its underside, large ears, and a black-tipped tail without a dark mane. Its large ears are often compared to those of the fennec fox.
Where Oregon’s Foxes Live
Oregon’s fox species inhabit different regions and environments. The red fox is highly adaptable and can be found throughout much of Oregon, including urban, suburban, agricultural, and forested areas. In forested regions, they utilize dense vegetation for cover and denning, while in agricultural landscapes, they frequent open fields and farmlands where prey is abundant. The Sierra Nevada red fox, a subspecies, has a more restricted distribution, primarily found in the higher elevations of the Oregon Cascades, including areas like Mount Jefferson, Mount Washington, and the Three Sisters Wilderness.
The gray fox primarily resides west of the Cascade Range in Oregon, favoring dense brush, woodlands, and rocky areas. They are often found in mixed forests, oak woodlands, and riparian zones along streams and rivers, particularly in the southwestern part of the state. While predominantly found in western Oregon, some gray foxes have been reported in counties immediately east of the Cascades, such as Hood River, Deschutes, and Klamath.
The kit fox has a highly restricted range in Oregon, representing the northernmost extent of its distribution. These foxes are found in arid, shrub-steppe, and grassland habitats primarily in southeastern Oregon, including parts of Harney and Malheur counties. They prefer areas with sparse ground cover, sandy soils, and low-lying shrubs, often utilizing dens in loose-textured soils. Kit foxes have also been observed near Klamath Falls and in Deschutes County.
Conservation and Status in Oregon
The conservation status of Oregon’s fox species varies significantly, with some populations stable and others facing considerable challenges. The red fox population in Oregon is generally considered stable or increasing due to its adaptability to various environments. It is classified as a furbearer in the state. However, there are ongoing studies to differentiate between native Rocky Mountain red fox populations in northeastern Oregon and non-native red foxes, some of which originated from fur farming operations.
The gray fox population in Oregon is also relatively stable and is classified as a furbearer. While generally not considered threatened, their populations can be influenced by habitat loss, hunting, and disease. Research on gray foxes is less extensive compared to other species, leading to some knowledge gaps regarding their population dynamics.
The kit fox in Oregon is a species of significant conservation concern, listed as “threatened” at the state level and a “Strategy Species” under the Oregon Conservation Strategy. The Oregon population is small and considered critically imperiled, with estimates suggesting as few as 20-40 individuals. Major threats to kit foxes include habitat loss and fragmentation, often due to altered wildfire regimes, invasions of non-native grasses, and expanding energy development. Vehicle collisions and predation by coyotes also impact their populations. Conservation efforts involve ongoing research to monitor distribution, habitat use, and population trends, including camera surveys and GPS collaring to gather crucial data for management decisions.
