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 Nature Conservancy (TNC) recently completed an unprecedented assessment of almost 14,000 dams in the Northeastern United States. The Northeast Aquatic Connectivity (NAC) project allows fisheries managers and other interested parties to assess dams at multiple scales based on their potential to benefit anadromous and resident fish species if removed or bypassed. This work has continued, with support from NOAA and USFWS, in the Chesapeake Bay watershed, where data refinements and further analysis have produced a web map and tool that allow users to interactively prioritize dams for mitigation at multiple scales and with varying criteria.The Southeast Aquatic Resources Partnership (SARP) has recently completed...

Developing consistent region-wide information to ensure enough water for people and wildlife.

This dataset includes the field measurements and laboratory analyses of surface water, seston, and sediment collected from Lake Powell, within Glen Canyon National Recreation area (GLCA), during high flow (May-June 2014) and low flow (August 2015) conditions. The study area includes 12-13 sampling sites that follow a transect spanning the entire length of the reservoir from the Colorado River inflow to the Glen Canyon dam, as well as the San Juan River arm, the Escalante River arm and West Canyon. Bed sediment samples were analyzed for mercury speciation, methylmercury production and degradation rates, total reduced sulfur, iron speciation, organic content, and 16S rRNA gene templates as a proxy for microbial abundances....
