The Northern Goshawk (Accipiter gentilis) has been a species of concern in the western United States since it was thought to be in decline in the 1970s. Loss of critical breeding and wintering habitat has contributed, in part, to this decline. In the U.S., the goshawk was listed in 1991 as a sensitive species for the Intermountain Region of the Forest Service. This region includes all National Forests in Utah. The goshawk also holds the status of a Management Indicator Species (MIS) on all six National Forests in Utah (USDA Forest Service 1999). The aim of the Forest Service was …

Species are defined using a variety of different operational techniques. While discussion of the various methodologies has previously been restricted mostly to taxonomists, the demarcation of species is also crucial for conservation biology. Unfortunately, different methods of diagnosing species can arrive at different entities. Most prominently, it is widely thought that use of a phylogenetic species concept may lead to recognition of a far greater number of much less inclusive units. As a result, studies of the same group of organisms can produce not only different species identities but also different species range and number of individuals. To assess the …
