Great gray owl habitat selection and home range characteristics during the breeding and post-fledging periods


November 2017 - June 2020


The Great Gray Owl is a species of conservation concern in Wyoming, and associated with older-aged, boreal forest habitats which are affected by wildfire, disease and beetle outbreaks, drought, climate change, logging and development. Very little is known, however, about Great Gray Owl habitat requirements and territory size during the nesting and post-fledging periods. The primary project partners are the Wyoming Game and Fish Department and Teton Raptor Center, with cooperation from the National Park Service and U.S. Forest Service. Information generated from the study will significantly enhance the state's ability to address the unknown aspects of the species' biology, update the species’ account in the State Wildlife Action Plan, and provide insight for the implementation of future monitoring efforts and management strategies.
