Cortex developed and implemented spatially explicit habitat and territory models for assessing patterns and trends in Northern Goshawk (Accipiter gentilis laingi; NOGO) habitat over the coastal B.C. range of this threatened subspecies. The ecological background, conceptual models, and estimates of parameters for NOGO habitat use and territory dynamics were developed and documented by the NOGO Habitat Recovery Implementation Group. Cortex applied the model, in cooperation with the Province of British Columbia and the Government of Canada, to inform designation of critical habitat for Northern Goshawk and to inform BC coastal planning processes evaluating tradeoffs between economic and ecological forest values. The modeling framework has three key components: (i) a landscape projection model for projecting vegetation growth and disturbances; (ii) a deterministic model for mapping suitability of NOGO foraging and nesting habitat; and (iii) a stochastic model for determining placement and density of potential territories.
