In 1997, the Spotted Owl Management Plan was implemented in British Columbia to prevent the extirpation of this Endangered species from Canada. This plan currently maintains an average 62% (+/- 15% SD, n = 101) suitable habitat for Spotted Owls within 101 Long-term Activity Centres distributed among 21 Special Resource Management Zones (SRMZs) totalling 363,000 ha in the Chilliwack and Squamish Forest Districts. The long-term goal of the Spotted Owl Management Plan is to maintain eventually a minimum of 67% suitable habitat within these Long-term Activity Centres and thus stabilize the owl population. We monitored the occupancy of Spotted Owls within 40 survey areas inside and outside SRMZs between 1992 and 2001. We compared the change in occupancy observed during the study with the slow population decline predicted by a spatially-explicit simulation model used to assess the Spotted Owl Management Plan. Within our survey areas, Spotted Owl occupancy declined by 49% between 1992 and 2001. The average annual...
