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. Information on goshawk nesting habitat and foraging behavior, and the food and habitats of selected goshawk prey, was therefore synthesized to develop a set of management objectives, desired forest conditions, and management recommendations. Key objectives of the guidelines are to provide (1) nesting, post-fledging, and foraging areas for goshawks, and (2) habitat to support abundant populations of 14 primary goshawk prey. Thinning trees in the understory, creating small openings in the forest, and prescribed fires should help produce and maintain the desired forest conditions. Other habitat elements critical for maintaining both goshawk and prey populations include abundant snags and large downed logs, woody debris, interspersion of different tree sizes across the landscape, and the majority of a goshawk's home range in older-aged forests. These guidelines should also benefit forest health, soil productivity, and the habitats of other old-growth-dependent plants and animals.

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. Forests are now dominated by mid- and late successional species (Douglas-fir, white fir, and subalpine fir) rather than the early successional species (lodgepole and ponderosa pine). Along with these changes came suspected declines in goshawk populations. Goshawk habitat in Utah was assessed using potential vegetation types, current vegetation types, and expert knowledge. Subalpine fir (17 percent) and quaking aspen (10 percent) potential vegetation types were the most common forest types in the State. Nearly 95 percent of the subalpine fir potential vegetation type was rated as high or medium for nesting habitat, while nearly 90 percent of the quaking aspen potential vegetation type was rated as high or medium for nesting. Similarly, combining nesting and foraging preferences 70 percent of the subalpine fir potential vegetation type is rated as either high value or optimum habitat. In addition, throughout Utah all of the high value habitats are well connected. The present conditions of the forests and woodlands of Utah are prone to insect and disease epidemics in addition to the risk of stand replacing fires. To ensure the goshawk's continued existence in Utah will require the restoration of these degraded habitats and the protection of native processes.

"A primary mission of the U.S. Department of Agriculture Forest Service is multiple resource management, and one of the emerging themes is forest restoration. The National Silviculture Workshop, a biennial event co-sponsored by the Forest Service, was held May 7-10, 2007, in Ketchikan, Alaska, with the theme of "Integrated Restoration of Forested Ecosystems to Achieve Multiresource Benefits." This proceedings presents a compilation of state-of-the-art silvicultural research and forestry management papers that demonstrates integrated restoration to yield multiple resource benefits. These papers highlight national perspectives on ecosystem services, forest restoration and climate change, and regional perspectives on forest restoration and silvicultural practices to achieve multiple resource benefits from researchers and forest practitioners working in a broad array of forest types in the United States."
