Using funds from an NRDAR settlement, FWS obligated $557,810 ($2011) to TNC of Massachusetts for the purchase of permanent conservation easements on approximately 200 acres of riparian lands along the Housatonic River in Salisbury, Connecticut. Conservation of riparian habitat will help to (1) protect water quality; (2) protect nesting habitat for migratory songbirds and other wildlife, including several rare and endangered plants, turtles, salamanders and dragonflies; and (3) maintain the scenic, agrarian character of the region. These efforts provide a beneficial tradeoff from the harm to the river and associated wildlife caused by historical polychlorinated biphenyls (PCBs) contamination. Economic Impacts of...

Provisional Tennessee State Wildlife Action Plan (TN-SWAP) terrestrial habitat priorities versus results of the population growth model developed by the Tennessee Chapter of The Nature Conservancy, 2008, converted to percent projected developed landcover in the year 2040. Spatial growth model was developed using population growth projections from the University of Tennessee Center for Business and Economic Research (UT-CBER), county urban growth boundaries, 2000 census blocks, and various ancillary datasets.

This shapefile represents The Nature Conservancy’s (TNC) “essential forests” and “key connectors” in the Central Appalachians Whole System. Essential Forests are built around groups of large forest patches, ecoregional portfolio roll-up sites, and areas with high local integrity and high flow density (from M. Anderson’s resiliency analysis). Key Connectors provide physical linkages among essential forests, have high flow density, and may also include large forest patches and matrix blocks. The polygons were originally delineated by TNC staff at a workshop near Petersburg, West Virginia, on March 9 and 10, 2011. The boundaries were hand-drawn on paper maps and then hand-digitized by A. Watland (TNC-VA) and T. Gagnolet...

The National Park Service (NPS), in conjunction with the Biological Resources Division (BRD) of the U.S. Geological Survey (USGS), has implemented a program to "develop a uniform hierarchical vegetation methodology" at a national level. The program will also create a geographic information system (GIS) database for the parks under its management. The purpose of the data is to document the state of vegetation within the NPS service area during the 1990's, thereby providing a baseline study for further analysis at the Regional or Service-wide level. The vegetation at Devils Tower National Monument was mapped using 1:16,000 scale U.S. Forest Service Color Aerial Photography acquired July 29, 1993. The mapping classification...
