From single species management to ecosystem management, "The goshawk"

Publications Posted on: May 11, 2018
Natural resource management in the United States is in a state of flux now more than any time in history. Many of the concerns about forest management are related to the enforcement of the Endangered Species Act. This act focuses forest management on preserving the habitat of a single species.

The role of fire in sustaining northern goshawk habitat in Rocky Mountain forests

Publications Posted on: April 23, 2018
The northern goshawk (Accipiter gentilis), is a northern latitude, forest dwelling raptor. In the Western United States, goshawks live in most forests, including those dominated by western hemlock (Tsuga heterophylla (Raf.) Sarg.), lodgepole pine (Pinus contorta Dougl. ex. Loud.), ponderosa pine (Pinus ponderosa Dougl. ex Laws.), and western larch (Larix occidentalis Nutt).

Northern Goshawks: A 20 year study of ecology and habitat on the Kaibab Plateau

Pages Posted on: August 08, 2017
Research on the Kaibab has shown that goshawks, predators of birds and small mammals, are strongly food-limited. The local suite of prey depends on the amount, quality, and intermixture of the particular habitats needed by each prey. These include a fine-scale mix of small groups of mature trees with interlocking crowns for tree squirrels, woodpeckers, grouse, and other birds, and scattered, small grass-forb openings for rabbits, ground squirrels, grouse, and other prey. Interestingly, this habitat mix characterized the natural conditions of the ponderosa pine and mixed conifer forests on the Kaibab Plateau before initiation of fire suppression and organized tree harvests.

National Forest System lands provide valuable habitat for a wide-range of species. These publications and tools provide information regarding individual species and their habitats. The information here should be supplemented by information specific to the individual planning unit.

Northern goshawks on the Kaibab Plateau: A 20-year investigation into factors affecting their demography

Science Spotlights Posted on: August 26, 2016
The elusive northern goshawk, its forest habitats, and the habitats of its bird and mammal prey are significant conservation issues related to the management of forests throughout the hawk’s North American range.  The Rocky Mountain Research Station has been enumerating the population size and documenting the population ecology and demography of individual goshawks on Arizona’s Kaibab Plateau for 20 years with the objective of identifying the vegetation composition and structure of forests habitats that best supports their survival and reproduction.

Winter movements of adult northern goshawks that nested in southcentral Wyoming

Publications Posted on: June 15, 2016
Winter movements of four adult northern goshawks (Accipiter gentilis) that nest in southcentral Wyoming were monitored during the winter of 1992-93. Goshawks initiated fall migrations in early fall (primarily mid-September) while weather conditions are moderate. Female 1 migrated 185 km south of her nest. She wintered in a mountainous area in Colorado at a higher elevation (277 4 m) than her nest site (2500 m elevation).

Northern goshawk (Accipiter gentilis)

Publications Posted on: June 15, 2016
The Northern Goshawk (hereafter referred to as Goshawk) is a large forest raptor, occupying boreal and temperate forests throughout the Holarctic. In North America, it breeds from Alaska to Newfoundland and south (Fig. 1).

The northern goshawk in Utah: Habitat assessment and management recommendations

Publications Posted on: May 12, 2016
This assessment describes northern goshawk (Accipiter gentilis) habitat in the State of Utah. Because of fire exclusion, insect and disease epidemics, timber harvest, livestock grazing, or a combination of these factors the forests and woodlands of Utah have changed drastically since the early 1900's.

Management recommendations for the northern goshawk in the southwestern United States

Publications Posted on: May 12, 2016
Present forest conditions loss of a herbaceous and shrubby understory, reductions in the amount of older forests, and increased areas of dense tree regeneration reflect the extent of human influence on these forests. These changes may also be affecting goshawk populations.

The Northern Goshawk: Ecology and management: Proceedings of a symposium of the Cooper Ornithological Society

Publications Posted on: May 12, 2016
This collection of 22 papers summarizes the current state of knowledge on Northern Goshawks (Accipiter gentilis) within the scientific and management communities. The proceedings are presented in three sections. Research Approaches and Management Concepts contains overviews of research and management for goshawks, forest management to provide goshawk habitat, and field techniques.
