Protocol for monitoring standing crop in grasslands using visual obstruction.
A simple regression model using easily measured visual obstruction to estimate standing crop on sandy lowland range sites in the Nebraska Sandhills and visual obstruction in combination with a previously estimated regression model provides a simple, reliable, and cost effective alternative to the clip and weigh technique.
Vegetation sampling and measurement
Comparison of soil water used by a sagebrush bunchgrass and a cheatgrass community.
Highlight: Two contrasting plant communities occur on the Arid Lands Ecology (ALE) Reserve in south-central Washington, one dominated by a mixture of sagebrush and bluebunch wheatgrass and the other…
Flora and fauna associated with prairie dog colonies and adjacent ungrazed mixed-grass prairie in western South Dakota.
Prairie dog grazing decreased mulch cover, maximum height of vegetation, plant species richness, and tended to decrease live plant canopy cover compared to that on ungrazed mixed-grass prairie.
Prairie Dogs: An Ecological Review and Current Biopolitics
Abstract In recent years, people have interpreted scientific information about the black-tailed prairie dog (Cynomys ludovicianus) in various, and sometimes conflicting, ways. Political complexity…
Spatial Optimization of Prairie Dog Colonies for Black-Footed Ferret Recovery
A discrete-time reaction-diffusion model for black-footed ferret release, population growth, and dispersal is combined with ferret carrying capacity constraints based on prairie dog population…
Understory-overstory relationships in ponderosa pine forests, Black Hills, South Dakota
Under-story-overstory relationships were examined over 7 different growing stock levels(GSLs) of ponderosa pine (Pinus ponderosa) in the Black Hills, South Dakota to indicate that reasonably good predictive models can be developed for pole and sapling stands considered separately or combined.
Vegetation and Soils of Burrowing Owl Nest Sites in Conata Basin, South Dakota
On caracterise la vegetation et les sols des Terriers abandonnes de Cynomys ludovicianus et utilises pour nidifier par Athene cunicularia et on les compare avec ceux des terriers non occupes par…
Coyote foods in the Black Hills, South Dakota
No studies have been published in which the objective was to determine if coyotes are opportunistic predators, and the foods of coyotes have not been determined for many ecosystems that they in.
