Rafinesques big-eared bat range from NatureServe
This dataset consists of polygon range maps for terrestrial vertebrate species in Alaska. The maps are shapefiles between 0 and 12 MB in size to be used in OpenGIS or ArcGIS on a PC. Individual species range maps were developed using the best available known range of the species (derived from a variety of available point data sources), overlaid with watershed-scale units (8-digit HUCs; standard map for U.S. GAP project) for the state of Alaska in the Alaska Albers NAD83 projection. These maps present the data in the form that they were created in, are subject to change, and are freely available from the the Alaska GAP project.
The Shenanadoah Salamander (Plethodon shenandoah) is an endangered salamander found only in the mountains of Shenandoah National Park. Field surveys of the salamander were conducted from 2007-2022 using daytime cover object surveys. In order to capture the totality of P. shendandoah’s range we sampled from low to high elevation across a broad geographic range. We created a spatial generalized additive model with aspect, latitude, longitude, and elevation and heat load index (HLI) to predict salamander occupancy and create a new range map based on our extended surveys. All spatial covariates were extracted from a 15m digital elevation model layer of Shenandoah National Park. Temperature and precipitaiton data were...
