Book Description
"The Habitat Suitability Indices for the black-tailed prairie dog was developed using the geospatial modeling capabilities of ArcGIS®9.2 Software and multi-criteria evaluation models. The modeling procedure was based on habitat variables, which cover the most essential habitat characteristics of species preferred habitats as described in the peer-reviewed literature and including personal contacts with species experts in Colorado, USA. In the models, key variables that apply to respective species are analyzed and results is rated from zero (unsuitable) to five (highly suitable) on the map. Variables used in the models include land cover class, elevation limits, slope, and hydrology data. It is relatively easy to modify the models, e.g. to include different viewpoints about variables that determine suitable habitat for the black-tailed prairie dog. Where capture or sampling data are available, the results of the models are tested using spatial statistical methods. GIS data of the black-tailed prairie dog colonies for they year 2000 were used to verify the ability to accurately predict the HSI model output between the suitable habitat areas and breeding site locations of the species. Validation of the HSI model provides evidence that the model works. The HSI model provides important for conservation biologists and land managers concerned with preserving black-tailed prairie dog diversity in the Comanche National Grassland, Colorado, USA" - Abstract.
