Integrating single-species management and landscape conservation using regional habitat occurrence models: the northern goshawk in the Southwest, USA

摘要: Conservation planners and land managers are often confronted with scale-associated challenges when assessing the relationship between management objectives species conservation. of individual typically involves site-level analyses habitat, whereas focuses on larger spatial extents. New models needed to more explicitly integrate species-specific conservation landscape or regional scales. We address this challenge an example using northern goshawk (Accipiter gentilis), a forest raptor circumpolar distribution that is focus intense debate regarding public lands in southwestern USA. To goshawk-specific habitat across area 22,800-km2 Arizona, we focused territory scale rather than nest sites. compiled 17-year database 895 sites estimate locations. then estimated likelihood occurrence for entire multiple logistic regression within expert-driven, spatially balanced, information-theoretic framework. Our model incorporated structure variables were derived from USFS Forest Inventory Analysis plots high-resolution satellite imagery. Results indicated high canopy-bulk density, intermediate canopy-base heights, low variation tree density strong predictors occurrence. used model-averaged parameter estimates these map explore patterns jurisdictions ecological subregions. iterative modeling approach complements previous demographic studies region. It also provides robust framework integrating ongoing future planning efforts.
