Mean Annual Precipitation by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Mean annual precipitation (mm/year) at a 1 kilometer resolution throughout the Appalachian LCC region.

Forest Biomass by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Forest biomass at the 1 kilometer scale throughout the Appalachian LCC region.

Terrestrial Species Richness by County by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Distribution of terrestrial species richness at the county scale throughout the Appalachian LCC region.

Terrestrial Species Richness by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Distribution of terrestrial species richness in 20 kilometer grids throughout the Appalachian LCC region.

NatureServe Regions and Karst by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Three basic regions are identified by NatureServe; Interior Low Plateaus,Central Appalachians, and Cumberland Southern Blue Ridge. These ares are displayed along with karst resources within the Appalachian LCC region.

Single County Endemic Species by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Number of endemic species at the county level throughout the Appalachian LCC region.

Single Grid Cell Endemics by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Many aquatic and terrestrial species are geographically rare, often found in a single cave. This map dis[;ays the geographic distribution of endemics scattered throughout the Appalachian LCC region.

Stygobiont and Troglobiont Endemics by Cave by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Total number of stygobiont and troglobiont endemic species within a cave.

Carbonate/Non-carbonate Contact Linear Sum by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Cumulative lengths of contacts between karst and non-karst, measuring both patchiness of available habitat and perhaps dispersal corridors if cave passages are differentially developed along these contacts. This information can be used to predict presence/absence of particular ecological groups in caves.

Cave Species Richness Hotspots by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Caves with the most aquatic and terrestrial species. The number of species is highly dependent on sampling intensity, including the number of sampling trips.

Percentage of Karst Area within Grid Cell by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Each cell represents the percent of karst within a 20 x 20 kilometer grid cell, a measure of habitat quantity. This attribute can be used to predict presence/absence of particular ecological groups in caves.

Terrestrial Records by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: The karst map provides the basic template for analyzing the distribution of cave species. Almost without exception, all caves occur within the karst areas. There were a few records of cave-dwelling species from outside karst areas (mostly springs) but the data was trimmed to fit within the karst areas, with a 1 km buffer to allow for errors in georeferencing). This map displays the aquatic records within karst areas in the Appalachian region.

Study Area Carbonate Bedrock Exposure Map by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: This map depicts the carbonate bedrock exposure within the study area.

Cave Count per 20km Grid Cell by Jessica Rhodes, last updated: Mar 11, 2016 09:47 AM: Total number of caves within a 20 kilometer grid cell. Each cell represents a range of caves found within that area.

Probability of Presence by Species Group by Jessica Rhodes, last updated: Mar 11, 2016 09:46 AM: Prediction maps for each of the nine groups. These are potentially important both to predict areas where to find particular groups and to determine regions of overall high habitat quality where species richness is expected to be high.

Land Use and Potential Risk Maps by Jessica Rhodes, last updated: Mar 11, 2016 09:46 AM: This folder contains maps of land use and potential risk.

Study Overview Maps and Foundational Datasets by Jessica Rhodes, last updated: Mar 11, 2016 09:46 AM: Overview maps for the Classification and Mapping of Cave and Karst Resources within the Appalachian region.

Bat Summary for Appalachian LCC Cave/Karst Study by Jessica Rhodes, last updated: Mar 10, 2016 03:55 PM: This document contains a list of the bat species that regularly use caves and mines in the Appalachian LCC region, federal status of these species, and sources of bat data.

Guidelines for Using the NatureServe Climate Change Vulnerability Index by Lesley Sneddon, last updated: Mar 10, 2016 12:26 PM: Motivated by the need to rapidly assess the vulnerability of species to climate change, NatureServe developed a Climate Change Vulnerability Index. The Index uses a scoring system that integrates a species’ predicted exposure to climate change within an area and three sets of factors associated with climate change sensitivity, each supported by published studies: 1) indirect exposure to climate change, 2) species-specific sensitivity and adaptive capacity factors and 3) documented response to climate change. Our primary goal for the Index is to provide valuable input for key planning documents, such as revisions of state wildlife action plans, to allow consideration of climate change impacts together with other stressors. We also hope this tool will help land managers develop and prioritize strategies for climate change adaptation that lead to actions that increase the resilience of species to climate change.
