The northern goshawk is classified as a Sensitive Species in all USDA Forest Service regions, including on the Black Hills National Forest in western South Dakota and northeastern Wyoming. An assessment was conducted of the quality of northern goshawk nesting and foraging habitat, along with the habitat quality of 22 of the goshawk’s prey species....

... and grouse (Galliformes) are an important food source for goshawks in the Black Hills. These ground-dwelling birds are in the larger size class of goshawk prey and return a lot of biomass for the energy the goshawks expend in capturing them ( fig. 25). Given the opportunity, goshawks will prey on young wild ...

... the Black Hills, robins are typically found wherever there are trees. Robins use ponderosa pine, white spruce, quaking aspen, and bur oak forests in various combina- tions and amounts (Franzreb and Ohmart 1978;Panjabi 2001;Pettingill and Whitney 1965;Sallabanks and James 1999;Savard and Falls 1981;Siegel 1989;Stauffer and Best 1980;Yahner 1983) (fig. 27). ...

... and cottontail rabbits (lagomorphs) are some of the larger prey that goshawks feed on in the Black Hills, making them high value ( fig. 29). In the Black Hills, eastern (Sylvilagus floridanus similis) and mountain cottontails (Sylvilagus nut- talli grangeri) occupy brushy ravines, streamside thickets, and the forested edges of Much like with the ground squirrels and turkeys, the greatest occurrence of high-rated habitat for the jackrabbits and cottontails occurs in the ...

... Idaho, nests in ponderosa pine and Douglas-fir trees averaged 15.5 inches (39 cm) DBH, and in Oregon, ponderosa pine nest trees averaged 12.2 inches (31 cm) DBH ( Bull and others 1986;Dixon and Saab 2000). In the Black Hills, the probability of a black-backed woodpecker selecting a nest tree was negatively associated with increasing tree diameter (Bonnot and others 2009). Black-backed woodpeckers may select small trees for nesting due to the greater proportions of sapwood to heartwood. ...

... range as far north as the central disturbances that create forest openings, such as thinning or wildfires, can favor chip- munk occupancy. In New Mexico and Arizona, thinning and wildfires that resulted in more snags, stumps, and even slash piles left after thinning were beneficial to least chipmunk populations (Converse and others 2006). Similarly, forest diversity created by ski runs in spruce-fir forests in Colorado with and without scattered trees in them provided habitat favored by these chipmunks (Hadley and Wilson 2004b). ...
