Forest Retention Index classes for the southeastern United States at 2040 were processed using the Forest Retention Decision Tree and rendered on a 30-meter by 30-meter grid. The Forest Retention Index is used only for current forestland, identified using National Land Cover Database 2011. Many datasets were used as inputs for the Forest Retention Decision Tree, and they can be grouped into five broad categories: Protected, Tier 1 Priority, Tier 2 Priority, Threats to Forest Retention, and Socio-Economic Value of Forests. Protected datasets include Protected Areas Database-United States, National Conservation Easement Database, state-maintained databases, and private datasets volunteered by conservation partners....
The project “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” assessed terrestrial ecological systems in terms of suitability as broadly defined habitats supporting species identified in wildlife action plans. Assessment of three Southern Yellow Pine Forest classes (Longleaf Pine Flatwoods, Longleaf Pine Woodland, Shortleaf/Loblolly Pine Woodland) included threshold values associated with landscape configuration and patch size. Per-pixel assessment of these thresholds required a layer describing pine forest areas in the landscape. This layer was created by selecting the three pine classes mentioned above, along with Managed Forest, from the Mid-South Terrestrial Broadly Defined...
Assessment of Upland Hardwood Forest and Woodland used a measure of the proportion of Oak and Hickory in the forested landscape. This folder contains two data layers: The interpolated Oak Hickory basal area values obtained from USFS (ranging from 0 – 284.777), and a layer describing the proportion of oak hickory created by dividing the Oak Hickory layer by the Interpolated Basal Area of Live Trees data layer (ranging from 0-1). Source data obtained from the USFS live tree species basal area of the contiguous United States (2000 – 2009) data product, which integrates vegetation phenology from MODIS imagery with extensive FIA field plot data of tree species basal area to map species distribution and basal area at...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
