Vaseux-Bighorn National Wildlife Area (NWA), 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 to be special and important, including the charismatic California bighorn sheep, which was considered endangered at the time. The Vaseux-Bighorn NWA provides significant habitat to federally listed species at risk as well as many species of migratory birds and other wildlife. The NWA is 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 Vaseux Lake and one of the area's most charismatic wildlife species, the California Bighorn Sheep. The Canadian Wildlife Service (CWS) manages several separate units of land which comprise the Vaseux-Bighorn NWA. 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.

Planning Your Visit
Follow a short boardwalk through Vaseux-Bighorn NWA and you'll be rewarded with magnificient views of the beautiful landscape from the wildlife viewing tower. Don't forget your camera!
The boardwalk and an information kiosk are both accessible from a small parking lot and some public events are offered locally by the Okanagan Similkameen Conservation Alliance.
Public facilities: a small parking lot, a boardwalk, an information kiosk, and a wildlife viewing tower.
Vaseux Bighorn is one of ten NWAs receiving funding as part of Canada's National Conservation Plan -- established to conserve Canada's precious wildlife and to ensure that you have access to discover the nature around you. Visit, connect with nature, and leave only footprints behind.
For more information on what is permitted in NWAs, consult the NWA Management and Activities page.
Access to the National Wildlife is from Highway 97 (five km south of Okanagan Falls and nearly 15 km north of Oliver).

Long description for the Map
Map showing the area around the Vaseux Lake in the Okanagan region of southern British Columbia. The boundaries of the Vaseux-Bighorn and the Vaseux Lake Migratory Bird Sanctuary are indicated. The contains six different distinct units and the migratory bird sanctuary covers the lake as well as a portion of land to the north-west of the lake. The units are named according to their location with respect to Vaseux Lake. The Northwest Marsh Unit and the Northern Wetlands Unit overlap with the migratory bird sanctuary. The other units are the Northeast Uplands unit, the Westside Unit, the Southeast Uplands Unit and the Irrigation Creek Unit, which is located a couple of kilometers to the East of the lake. The scale on the map is in kilometers. Permanent water, roads and highways are all indicated on the map. A small, inset national map situates the in Canada.
