Vaseux-Bighorn National Wildlife Area, California Bighorn Sheep.
The Vaseux-Bighorn National Wildlife Area (NWA) is located in the south Okanagan–Similkameen region of British Columbia. The NWA was established in 1979 to protect habitat for species deemed, at the time, to be special and important; including the charismatic California bighorn sheep, which was considered endangered. The Vaseux-Bighorn NWA provides significant habitat to species at risk as well as many species of migratory birds and other wildlife. The NWAis a dynamic natural system influenced by erosion, flooding, fire, grazing, and other natural processes. The NWA is important not only as habitat for local wildlife but also is part of an important habitat corridor for migratory species.
The Vaseux-Bighorn NWA officially became a federal property in 1979. The wildlife area took its name from the Vaseux Lake reservoir and the area’s keystone wildlife species, the California Bighorn Sheep. The Canadian Wildlife Service (CWS) manages several separate units of land which comprise the Vaseux-Bighorn NWA. In addition to private land holdings, the NWA is also adjacent to Vaseux Lake, a federal Migratory Bird Sanctuary (est. 1923), and other conservation land holdings protected by the province, Nature Trust of British Columbia, The Land Conservancy of British Columbia and the Nature Conservancy of Canada.
The NWA includes habitats that extend from wetlands and riparian thickets around Vaseux Lake up to arid terraces dominated by antelope bitterbrush, and finally up to rugged hillsides, dominated by exposed rock and ponderosa pine. Old ponderosa pine and Douglas-fir parklands in the area create habitat for cavity nesting birds including Lewis’s and White-headed Woodpeckers. Grasslands dominated by antelope-brush, sagebrush and blue bunch wheatgrass are unique to this area and provide suitable habitat for species such as Behr’s Hairstreak and several bird species including the Long-billed Curlew. Extensive wetlands surrounding the Okanagan River channel and dyke system at the north end of Vaseux Lake provide excellent migratory bird habitat.

National Wildlife Areas (NWAs) are protected and managed according to the Wildlife Area Regulations under the Canada Wildlife Act. The primary purpose of NWAs is the protection and conservation of wildlife and their habitat. For this purpose, and according to the legislation, Environment Canada can prohibit all activities in a NWAthat could interfere with the conservation of wildlife. Consequently, most NWAs are not accessible to the public and all activities are prohibited. Nonetheless, Environment Canada has the ability to authorize some activities, whether through public notice or the issuance of permits, as long as these are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.
Access to the majority of the Vaseux-Bighorn NWA is restricted, the bulk of the NWA being closed to public access for the purposes mentioned. However, walk-on and non-motorized boat access to the adjacent Vaseux Lake Migratory Bird Sanctuary for wildlife viewing are permissible without a permit. Public access is allowed on designated trails, and on the wildlife viewing tower and boardwalk. Some activities may be permitted as per the management plan conservation goals. Public notices listing the authorized activities in the wildlife area are posted at access points. For some types of activity, additional federal or provincial permits may be required.
More information on access and permitting for Vaseux-Bighorn NWA can be obtained by contacting the Environment Canada regional office.
