GIS procedures for analyzing wildlife topics in a national park in Virginia

Abstract

A set of procedures for geographical information system analysis of wildlife-related problem areas associated with Virginia National Parks is presented. Analyses of both faunal and floral topics were made. The procedures presented address (1) evaluation of habitat resources available for reintroduction of bobcat (Lynx rufus); (2) mapping of avian species richness, (3) impacts of park boundary development on forest-interior bird species, and (4) identification of areas Suitable for threatened and endangered species (e.g., the small whorled pogonia, Isotria medeoloides). The GRASS GIS was used for the analyses. Inputs included data on elevation, slope, soils, landuse/landcover, roads, and hydrography. The procedures are built upon standard GIS techniques (e.g., overlays and “buffer” zones) and should be applicable to the mapping of habitat, species richness, and other information for various taxa in other resource areas.
