Book excerpt: Excerpt from Evaluation of a Habitat Capability Model for Nongame Birds in the Black Hills, South Dakota Coefficients in the habcap model quantify rela tive (o to capability of each structural stage as habitat to sustain a prescribed population density for each species. The habcap model includes separate coefficients for feeding and cover. Although feeding and cover coefficients are the same for most species, we based our test of the model on cover coefficients because cover includes nest placement in breeding territories. Abundance of bird species at each site Was the sum of observations S50'm from the count point. We used bird count data from 1992 and 1993 to test hypotheses that the observed abundance in each structural stage was similar to predicted abundance by the habcap model using chi-square goodnessof-fit tests (freese Chi-square tests were made only for structural stages with coefficients >0. Since fewer counts were made in old-growth and dry meadows, predicted abundance in these structural stages was adjusted to represent the proportion of total count days. Predicted abundance of bird species (pnj) in each structural stage (ssi) was calculated as. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Habitat Capability Model for Birds Wintering in the Black Hills, South Dakota written by Mark A. Rumble and published by . 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.

Download or read book Arc Habitat Suitability Index Computer Software written by Thomas M. Juntti and published by . This book was released on 2006 with total page 38 pages. 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.

Download or read book Stream Channel Responses to Streamflow Diversion on Small Streams of the Snake River Drainage, Idaho written by Carolyn C. Bohn and published by . This book was released on 2000 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects on channels of small, low-head seasonal water diversions in the Snake River drainage were investigated. Channels below small diversions were compared to the channels immediately above the same diversions to determine if differences in flow conveyance, substrate sediment size distribution, or streamside vegetation density were present. Estimates of flow conveyance were greater above the diversions, as measured by the area between the edges of vegetation on both banks, and by frequent-flow indicators, which generally approximated bankfull stage. No significant difference in substrate particle size or in channel roughness was found between channels above and below diversions. Although use histories of the diversions were not available, limited observations and conversations with users suggest that many of the diversion structures did not substantially divert high springtime flows so that passage of channel-forming flows probably occurred. Some diversion structures apparently divert or trap a portion of the bedload. Stem diameters of vegetation 6 to 48 inches above the ground were significantly larger above the diversions. Tests of stem densities were not significant. Stratification by substrate, season and size of diversion, community type, and source of summer water may be necessary to properly evaluate the effects of small diversions on vegetation stem density and vigor. The elevation of the edge of vegetation appears to be a viable alternative to frequent flow or bankfull indicators for estimating flow conveyance. It also addresses the question of vegetative encroachment into the channel. Use of the edge of vegetation as a channel feature for flow estimates merits further testing. It appears that the operation of the small forest stream diversions studied has not substantially altered most of the parameters studied. Past hydrographs and historical hydrologic data, however, are needed to fully evaluate the channel and vegetation responses.
