In 2004, call-playback surveys were conducted within the Bridge Coastal Fish and Wildlife Restoration Program (BCRP) study area. The primary objective of these surveys was to better determine the current distribution and range of the endangered (COSEWIC) Spotted Owl (Strix occidentalis caurina - Merriam) at the northern extent of the species range in North America. Financial support for the surveys was provided by BCRP and the Ministry of Water, Land and Air Protection (MWLAP).

Goals and Objectives The objective of the study was to conduct Spotted Owl occupancy and breeding surveys to determine the population distribution of the Spotted Owl in the BC Hydro operational footprint areas of the Seton and Bridge watersheds. The selected study areas contained suitable habitat and/or previous Spotted Owl detections, yet had limited or no previous inventory information. In 2003 the Seton/Anderson watershed had been established, through telemetric monitoring of juvenile dispersal movements, to provide important connectivity habitat between two discrete owl populations. This find emphasized the need for a comprehensive inventory effort in the Seton/Anderson watershed. Management and recovery strategies have recognized that intensive and range-wide inventories of the Spotted Owl are necessary to better determine the current distribution of the population remaining in BC. The inventory of these watersheds for Spotted Owls could prove to be extremely important in determining owl activity, thus influencing management and recovery strategies for the Spotted Owl in British Columbia and the immediate watersheds. Additional Spotted Owl detections for the province could further help determine connectivity corridors, population densities and augmentation options for this endangered owl species.
