“…Of these habitat variables, steep slopes were significantly positively associated with Virginia's Warbler across all survey points, but not when the analysis was restricted to occupied canyons, and slope (as well as pine cover) could not be included in logistic regression models because of insufficient variability at the points surveyed. Indeed, most of the mahogany-dominated shrub habitats in the southern Black Hills are characterized by slopes ranging from 12° to 21° and shrub cover ranging from 43% to 53%, with occasional scattered pines and Rocky Mountain junipers (Juniperus scopulorum) (Hoffman and Alexander 1987). Thus the habitat elements Virginia's Warblers require are common in the PJS habitats of the southern Black Hills.…”

“…In Nevada, quaking aspen ranges from 1,981 to 2,347 m in the northern part of the state, 2438 to 2957 m in the southern part of the state, and as low as 1,535 m in riparian zones (Manning and Padgett 1995;Mueggler 1988). In the Black Hills of South Dakota, quaking aspen is most prevalent between 1,219 and 1,902 m (Hoffman and Alexander 1987).…”

“…Dense overhead canopy cover provides a cool environment, which may allow deer to avoid heat stress (Bunnell et al 1986, Hoffman andAlexander 1987) and reduce cutaneous water loss (Parker and Robbins 1984).…”
