The Spotted Owl Inventory and Research Advisory Committee (SORIAC) developed a research and inventory strategy in 1997 to support the adaptive nature of the Spotted Owl Management Plan. One component of this plan involves the radio-tracking of 18 spotted owls (Strix occidentalis caurina) in southwest British Columbia to determine annual home range size and habitat use. To date 12 spotted owls (5 males and 7 females) have been radio tagged, with nighttime and daytime relocations being utilized to determine nesting, foraging and roosting locations respectively. To determine habitat selection, forest cover data from the British Columbia Ministry of Forests will be tested by ground sampling in the Chilliwack and Squamish forest districts. Characteristics of each type of habitat used will be determined for a coastal and interior ecosystem and possibly a third transitional ecosystem. Based on Washington State habitat classifications, habitats used will be delineated into type A, type B, type C and...
