Summary
These are the most important input layers for the project “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South.”
Name: Known Prairie Patches in the GCPO
Description:
Polygons describing prairie patches from five states (Alabama, Arkansas, Mississippi, Missouri, Texas). This layer consists of 14,765 polygons totaling 54,419 acres. 14,595 polygon features were obtained from the Alabama Natural Heritage Commission (see Schotz and Barbour, Ecological assessment and terrestrial vertebrate surveys for Black Belt Prairies in Alabama, 2009). Arkansas prairie patch polygons were obtained by comparing prairies described by Adelman and Schwartz (Prairie Directory of North America, Oxford University Press, 2013) to those described by Arkansas Natural Heritage Commission (www.naturalheritage.com) and selecting corresponding polygons from the Protected Areas Database of the United States (PAD-US). Mississippi prairie polygons were obtained directly from the Mississippi Natural Heritage Program. Missouri prairie polygons were obtained by comparing prairies described by Adelman and Schwartz to those described by the Missouri Prairie Foundation (www.moprairie.org) and selecting corresponding polygons from PAD-US. Two Texas prairie polygons were obtained by reviewing Adelman and Schwartz and selecting corresponding polygons from PAD-US.

Name: Interpolated Basal Area of Live Trees
Description:
The “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project used basal area data 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 250 meter spatial resolution for the 48 conterminous U.S. states. This version has been clipped to the project area, projected to NAD 1983 Albers, and resampled to 30 meters spatial resolution.

Name: Percent Overstory Canopy Cover
Description:
The “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project obtained per-pixel percent overstory canopy data from the NLCD 2011 USFS Tree Canopy analytical (CONUS) layer. This layer was clipped to the study area boundary and projected to NAD 1983 Albers. Individual binary layers expressing desired ranges of percent overstory canopy cover were developed for each targeted Broadly Defined Habitat (BDH) class.
Name: LANDFIRE Existing Vegetation Type
Description:
LANDFIRE Existing Vegetation type (Vintage April 2017, acquired April 2018) is a principle input layer to the Broadly Defined Habitat (BDH) map developed by the “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project. This version clips the LANDFIRE product to the project study area. The 281 ecological system and land cover classes in this map were crosswalked to the fifteen BDH classes used by the project.
Name: LANDFIRE Biophysical Settings
Description:
The LANDFIRE Biophysical Settings data layer was used by the “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project to map potential for restoration of targeted Broadly Defined Habitats (BDH). This version is clipped to the project study area. The 113 named ecological systems in this layer were crosswalked to the twelve potential BDH classes identified by the project.
Name: Texas and Oklahoma Ecological Systems
Description:
The “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project developed a map of Broadly Defined Habitats (BDH) associated with wildlife species of conservation concern. The map used Ecological Mapping Systems data from the Texas Parks and Wildlife Department in Texas and Ecological System Mapping data from Missouri Resource Assessment Partnership (MoRAP) in Oklahoma as inputs. Those products were resampled from 10 to 30-meter resolution and translated to BDH classes.
Name: Florida Ecological Systems
Description:
The “Modeling Habitat Connectivity to Support State Wildlife Action Plans in the Mid-South” project developed a map of Broadly Defined Habitats (BDH) associated with wildlife species of conservation concern. The map used the Cooperative Land Cover Map from the Florida Fish and Wildlife Conservation Commission. The “Site” level classification was used, and the map was projected into NAD 1983 Albers, resampled from 10 to 30-meter resolution and translated to BDH classes.
Name: Basal Area Oak Hickory
Description:
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).
