The Spotted Owl lives in old growth coniferous forests in the southwestern mainland of British Columbia, where its numbers have dwindled from about 200 individuals in 1992 to less than 20 individuals in 2007 (COSEWIC 2008e). Habitat loss and competition from Barred Owls are two important threats to this species in Canada, but the biggest hurdle it now faces is that the few remaining individuals are isolated in small pockets of fragmented habitat (COSEWIC 2008e). It is endangered in Canada and declining throughout its small continental range. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Few bird species have attracted more conservation and management attention in the past few decades than the Spotted Owl. In Canada and the northwestern United States, the species requires large home ranges (2100-4000 ha) in mature or old growth coniferous forests (Gutiérrez et al. 1995). More than half of this habitat has been lost to forest harvest and agricultural and urban developments in the past century, and much that remains is in small fragments at higher elevations (COSEWIC 2008e). The Barred Owl, a new immigrant to forests west of the Rockies, is a strong competitor for territories and prey since it arrived in the 1970s; by the mid-1990s it was four times as abundant as Spotted Owls within the latter species' range in British Columbia (COSEWIC 2008e). No juvenile Spotted Owls in the Canadian population have survived to adulthood since monitoring began in the 1990s (COSEWIC 2008e). Current plans to conserve this species in Canada include the protection of all sites where Spotted Owls were known to occur in 2005, the removal of Barred Owls from active Spotted Owl breeding territories, and the implementation of a captive breeding program (BC Ministry of Agriculture and Lands 2008).

Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
