Nest site and perch locations were derived from the NLCD (all forested cover types) were analyzed to determine the distance from Bald eagle potential suitable habitat. The quality of a HUC in relation to distance to nest site and perch locations was defined as good (3), fair (2), or poor (1). The score indicates the threat level for each attribute. A low score indicates a low threat, a medium score indicates a medium threat, and a high score indicates a high threat to the species. The values for each score were characterized in relation to distance from nest site and perch locations by 2km = poor.
