Interior Douglas-fir Zone

The Interior Douglas-fir Zone lies in the heart of British Columbia's southern interior. Often described as "cattle country," it has rolling hills and valleys covered by dry grasslands and open forests. Although it is best known for cattle ranching and forestry, this zone also supports a rich diversity of natural communities and wildlife species.

Tree species descriptions

The Interior Douglas-fir Zone spreads across low- to mid-elevations in the east Kootenays, the Okanagan-Similkameen and Thompson region, and southern parts of the Chilcotin and Cariboo. Most of the zone occupies the southern part of the Interior Plateau. To the west, the zone works its way up the leeward slopes of the Coast Mountains. In the east, it covers the southern portion of the Rocky Mountain Trench. Cranbrook, Vernon, Chase, Princeton, Boston Bar, Clinton, and Williams Lake all lie within the Interior Douglas-fir Zone.
