Northern Goshawk: Habitat Conservation Assessment for California
Northern goshawks are of increasing conservation attention because of concern regarding population trends and the effects of management on habitat. As a top-trophic level carnivore with large spatial requirements, low breeding density, and associations with late-seral forest structures for some aspects of their life history, goshawks exhibit ecological characteristics of species that may be particularly sensitive to forest management practices that reduce or fragment habitat. The species has been petitioned three times in the last ten years for listing under the Endangered Species Act throughout all or portions of it's range in western North America. Currently no information exists on population trends for any bioregion and knowledge of habitat requirements is limited. We are conducting a Habitat Conservation Assessment to compile and synthesize information on the distribution and ecology of northern goshawks (Accipiter gentilis) in California in order to evaluate their current status, generate management recommendations, and identify research and monitoring priorities.
To synthesize and evaluate historic and current distributional records
of northern goshawks in California to delineate current breeding
range and determine if there have been changes in the geographic
range of the species over the past century.
