Description: OwlStatus_Buf contain the management circles around the spotted owl site center locations that best represents the most recent territory center. United States Fish and Wildlife Service (USFWS) and Washington Department of Natural Resources (WADNR) are the primary regulatory agencies managing impacts to spotted owls. These agencies have adopted a management circle approach for assessing suitable habitat for spotted owls. From the site center location, a radius of 9504 feet (1.8 miles) or 14256 feet (2.7 miles) is used to evaluate the amount of remaining habitat. The smaller radius is used for owl sites east of the I-5 corridor, the larger radius is used west of I-5. The different radii reflect differences in home range sizes used by owls as determined by radio-telemerty.
