Lower Mainland Ecoregion

Lower Mainland Ecoregion

The Lower Mainland Ecoregion is the biogeoclimatic region that surrounds Vancouver, British Columbia, comprising the eastern edge of the Georgia Depression and extending from Powell River, British Columbia on the Sunshine Coast to Hope at the eastern end of the Fraser Valley. It thus corresponds, for the most part, with the popular usage of the term "Lower Mainland." The Lower Mainland Ecoregion is a part of the Pacific Maritime Ecozone.

The ecoregion is bounded by the Coast and Cascade Mountains and traversed by the Fraser River. It has a unique climate, flora and fauna, geology and land use. The following description is adapted from Environment Canada's Ecological Framework of Canada.
