Project number:
The project “Landscape Analysis of Habitat Supply and Effects on Populations of the Northern Spotted Owl in BC” was initiated in 2003 by the Canadian Spotted Owl Recovery Team (CSORT) to address questions specific to habitat supply and population for recovery planning for the Northern Spotted Owl (SPOW), an Endangered subspecies in Canada, facing extirpation from British Columbia (Committee on the Status of Endangered Wildlife in Canada 2001, Blackburn et al. 2002). The CSORT collaborated with modellers, analysts and topic experts to develop and test management/habitatfocused modelling approaches. The final model framework includes the following components 1) the spatially explicit SPOW habitat classification model, 2) the landscape dynamics model that projects forest growth and stand-replacing natural disturbances, 3) the population model, 4) the spatial timber supply model, 5) the structural (cost-surface) models to capture effects of dispersal and movement patterns on territory placement and connectivity between habitat areas, 6) a Bayesian belief network framework (BBN) for assessment of habitat quality that accounts for cross-scale influences of biological attribute states, their spatial configuration, and risk of loss of habitat to be integrated into a probabilistic model of habitat quality, and 7) a Resource Location Model for proactive habitat reserve selection that integrates changing habitat conditions with population or habitat targets through time.
