Journal Article
Amount of suitable habitat and viability of Northern Spotted Owls
1995
Overview
In 1990, in response to requests from the private sector, the U.S. Fish and Wildlife Service circulated draft guidelines to protect Northern Spotted Owls (Strix occidentalis caurina) from harm due to harvest of old-growth trees in proximity to nests or activity centers. The guidelines are often referred to as the \"40% guideline,\" the \"500-acre guideline,\" and the \"70-acre guideline.\" I comment on the rationales used to develop the guidelines and suggest ways the guidelines could be improved.
