Columbia National Wildlife Area

Columbia National Wildlife Area (NWA) is in southeastern British Columbia (BC). It provides important wetland habitat for migrating waterfowl.


Columbia NWA has four separate units: Wilmer, Spillimacheen, Brisco, and Harrogate. The NWA is located in the southern part of BC’s Rocky Mountain Trench, which separates the RockyMountains to the east from the Purcell and Selkirk Mountains to the west.

The NWA contains wetlands and lowland coniferous forest. It is actually part of a larger wetland system: the Columbia Wetlands. The Columbia Wetlands have a great diversity and variety of wildlife. They contain important resting and breeding habitats for waterfowl and migratory birds of the Pacific flyway.

In the late 1960s, the Canadian Wildlife Service (CWS) became interested in properties within the Columbia Valley. Many unprotected properties had important waterfowl habitat. CWS started negotiations to acquire goose production areas near Wilmer in 1970. By 1976, CWS purchased around 405 ha. In 1978 those lands became the Wilmer NWA. In 1977, the Nature Trust of BC began to acquire properties in the Columbia Valley. This was based on CWS’ recommendations.By 1984, the Nature Trust had purchased approximately 529 ha at Spillimacheen, Brisco, and Harrogate. CWS is currently leasing these properties. Together withthe Wilmer property, they form Columbia NWA.

There is more information on Columbia NWA in the summary table below.

CWS manages the four units of Columbia NWA. These areas provide important wetland habitat for migrating waterfowl. The NWA is also important for other wetland-dependent wildlife, fish, and plant species. This is especially the case for species considered rare, threatened, or endangered.

Under the Canada Wildlife Act, NWAs are protected and managed in accordance with the Wildlife Area Regulations. The primary purpose of NWAs is to protect and conserve wildlife andtheir habitat. For this purpose and according to the legislation, allactivities in a NWA that could interfere with the conservation of wildlife can be prohibited. Consequently, most NWAs are not accessible to the public and all activities are prohibited. However, some activities may be authorized through public notice or the issuance of permits as long as they are consistent withthe management plan goals for the NWA.

For more information, consult the NWAs Management and Activities section.

Access to the Columbia NWA is not restricted and activities may be permitted in accordance with the conservation objectives of the NWA management plan. Public notices listing the authorized activities in the wildlife area are posted at access points. For certain type of activity, additional federal or provincial permits may be required. Some seasonal activities such as hiking, canoeing, and wildlife viewing will be permitted provided that they do not result in negative impacts to the conservation values of the area.

More information on access and permitting for Columbia NWA can be obtained by contacting the Environment and Climate Change Canada regional office.
