This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat models have considerable economic effects on management decisions and are used to predict consequences of land management decisions on wildlife. The Black Hills National Forest uses the habitat capability model (HABCAP), but its accuracy relative to resident wintering bird populations is largely unknown. We tested the model's predictive accuracy for resident nongame birds wintering in 11 vegetation structural stages of ponderosa pine, quaking aspen/paper birch, and meadows in the Black Hills, South Dakota. Six species, hairy woodpecker, gray jay, black-capped chickadee, white-breasted nuthatch, red-breasted nuthatch, and dark-eyed junco, had HABCAP coefficients for vegetation structural stages during winter. Red crossbills were not previously included in the model, so we developed HABCAP coefficients for them. Predicted abundance of winter birds in vegetation structural stages based on HABCAP coefficients differed from observed abundance for gray jays, black-capped chickadees, white-breasted nuthatches, red-breasted nuthatches, and dark-eyed juncos. HABCAP coefficients were modified to reflect observed abundance patterns of birds. These changes to HABCAP coefficients should provide managers with more appropriate estimates of land management impacts on nongame birds wintering in the Black Hills.

Available in PDF, EPUB and Kindle. Book excerpt: Vegetation at the Glacier Lakes Ecosystem Experiment Site, a 600 ha research site at 3200 to 3500 m elevation in the Snowy Range of southeastern Wyoming, was categorized and described from an intensive sampling of species abundances. A total of 304 vascular plant taxa were identified through collection and herbarium documentation. Plots with tree species were separated from those without tree species for ordination and classification analyses. Detrended correspondence analysis was used to order plots along major axes of composition variation, which are inferred moisture and topographic gradients. Cluster analysis was used to categorize plots based on composition similarity. The resulting groups were named according to species dominants. We identified and described in detail 4 meadow, 4 thicket or scrub, 3 krummholz, and 2 forest plant associations.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem. We discuss the silvical characteristics of ponderosa pine, natural disturbances that govern ecosystem processes, wildlife habitat and management, various silvicultural methods to manage ponderosa pine forests, and watershed management of the Black Hills.

Available in PDF, EPUB and Kindle. Book excerpt: This user manual describes the Arc Habitat Suitability Index (ArcHSI), which is a geographical information system (GIS) model that estimates the ability of an area to meet the food and cover requirements of an animal species. The components and parameters of the model occur in tables and can be easily edited or otherwise modified. ArcHSI runs on personal computers with the full installation of ArcGIS (Version 8.2+). ArcHSI is a tool intended to inform planners of the probable impacts on wildlife for the alternatives they develop, and it augments, rather than supplants, the expertise of resource specialists with site-specific knowledge. System requirements are platform specific, but a typical system requires 512 megabytes RAM and a 1 gHz CPU. A Unix ArcINFO version is also available. We have included a demonstration (see DEMONSTRATION) that provides a step-by-step tour of the software, including setting up the first run; interpreting, formatting, and analyzing output; and identifying and solving the most common problems experienced by new users.
