Available in PDF, EPUB and Kindle. Book excerpt: Aspen (Populus tremuloides Michx.) stands are in decline throughout the Interior Western United States because of fire suppression, overbrowsing by domestic livestock and native ungulates, and forest succession. We measured summertime soil temperatures in stable aspen, decadent aspen, and mixed aspen/conifer stands; a mixed aspen/conifer clearcut; a mixed aspen/conifer forest that was burned in a lightning-caused fire; and a decadent aspen stand and mixed aspen/conifer stand that received prescribed burns. Soil temperature fluctuations and mean soil temperatures were greater in cut and burned areas than in untreated stands. In untreated stands, mean soil temperature increased in the order: mixed aspen/conifer -stable aspen - decadent aspen. Soils under the closed canopy of mixed aspen/conifer stands tended to remain cool in the summer favoring organic matter accumulation. The relatively open canopy of decadent aspen stands allowed for increased light penetration and soil heating favoring organic matter breakdown. Cutting and burning greatly increased summertime shallow soil temperature, also favoring increased organic matter turnover and aspen suckering. Postdisturbance regrowth of grasses and forbs and aspen suckering shaded soils. Eventually, soil temperature in treated or disturbed areas should approach that of stable aspen stands.

This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prairie woodlands comprise about 1 percent of the landscape in the northern Great Plains. However, prairie woodlands provide habitat for far more than 1 percent of the wildlife species that occur in the prairie region. With increasing pressures on natural resources, managers need methods for managing wildlife habitat and biodiversity that are based on ecological processes. We studied the small mammals and vegetation in seral stages of four woodland types in central South Dakota. None of the species was restricted to a single seral stage, but abundance of some small mammals varied depending on seral stages of woodland types. To ensure the biodiversity of the prairie, managers should retain all seral stages of all prairie woodlands.

Available in PDF, EPUB and Kindle. Book excerpt: Birds are indicators of vegetation structure and ecological conditions. The singing activity of birds declines during late-morning periods, which can affect estimates of abundance and conclusions regarding vegetative conditions indexed by birds. Therefore, it is important to quantify periods of bird activity so biologists can plan studies. We determined hourly detections from singing males of 22 nongame bird species in ponderosa pine, quaking aspen, and grassland vegetation types in the Black Hills of South Dakota. Detections of 12 of 22 species differed among 1-hr intervals after sunrise. Detections of yellowrumped warblers, Townsend's solitaires, red-breasted nuthatches, western tanagers, and American robins decreased on count-episodes more than 4 hrs after sunrise. Detections of dusky flycatchers declined on count-episodes more than 3 hrs after sunrise and detections of black-capped chickadees were greatest during the first hour after sunrise and declined afterward. Detections of many other species from songs or calls decreased on count-episodes more than 5 hrs after sunrise. We recommend that bird counts in the Black Hills be completed within 4 hrs after sunrise so estimates of bird abundance are not affected by reduced singing among males.
