Excerpt from A Proposed Delineation of Critical Grizzly Bear Habitat in the Yellowstone Region The Purpose of the Endangered Species Act of 1973 is to perpetuate threatened and endangered species and, where possible, to extend their populations. On 1 Sep tember 1975, the grizzly bear (ursus arctos horribilis) was listed as Threatened south of the Canadian Border. Thereby, all Federal Agencies conducting land management programs were required to prevent de struction or adverse modification of critical grizzly bear habitat. Critical habitat determination involved de lineating an area essential for the survival and recovery of the species. Federal Rules published 22 April 1975 defined critical habitat as the entire habitat or any por tion of it necessary to meet the nutritional and spatial needs of the species. It must provide for specific physi cal, seasonal, and behavioral requirements, as well as assure specialized sites for breeding, reproduction, and shelter. Most of the currently occupied range of the grizzly bear has been recommended for designation as critical habitat, following professional and agency recommen dations. A proposed rule-making, delineating critical grizzly bear habitat in the contiguous 48 states, was published in the Federal Register on 6 November 1976; public hearings that followed indicated widespread public and agency opposition. The Opposition was due, in part, to alleged economic, social, and jurisdictional conflicts and to a lack of sound scientific data cor roborating the delineation.
