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.
