The grassland condition index raster data layer assigns to each 30 meter pixel in the GCPO a condition index score generated by the presence or absence of a set of desired conditions such as patch size, vegetation height, etc. This grassland bar code layer indicates which conditions contributed to the index value score, and by how much, by use of a nine-digit code. The digits in the code represent the following input conditions in order: potential for restoration, presence of a grassland ecological system, presence of prairie (a subset of grasslands characterized by the presence or dominance of native vegetation), configuration in a patch > 100 acres, and the four site-level condition endpoints: vegetation height...
The distribution of upland streams and rivers predominantly lies in the Ozark Highlands subgeography and the Ouachita Mountains portion of the West Gulf Coastal Plains, with a small portion in the East Gulf Coastal Plain. This stream type is essentially absent from the other two subgeographies. Our assessment defined upland streams and rivers as free flowing streams having an average annual flow between 10 and 6,000 cubic feet/second (cfs) and sitting at an elevation >130 meters according to the National Hydrography Dataset (v2).
Open Pine Woodland and Savanna was assessed by evaluating endpoint variable values from spatial data layers. Spatial data inputs included a set of selected ecological system and land use classes from the National GAP Land Cover Data Product and estimated percent canopy cover from NLCD 2011. Midstory conditions, average tree diameter, and basal area endpoint thresholds were derived from US Forest Service data products that use remote sensing data to impute Forest Inventory and Analysis (FIA) data across the landscape. The Condition Index is a pixel-by-pixel analysis with a score range of 0 – 21 at a spatial resolution of 250 meters. The process first assesses whether the pixel is in a pine or mixed-pine forested...

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 HRUs available here are for an application of the Precipitation Runoff Modeling System (PRMS) in the southeastern United States by LaFontaine and others (2017). A Geographic Information System (GIS) file for the HRUs is provided as a shapefile with attribute hru_id_1 identifying the numbering convention used in the PRMS model. This GIS file represents the watershed area for an approximately 1.16 million square kilometer area of the southeastern United States.
This project integrates dynamic landscape population viability models and structured decision making to choose among conservation scenarios that best meet desired endpoints for focal wildlife species in the Ozark Highlands region under climate change.

The purpose of this data set is support resource allocation decisions (i.e. where to invest conservation effort) within the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative. The Management Opportunity action map for the Upland Hardwoods (Forest) habitat system ranks pixels (250-m) for 3 general classes of conservation actions. Maintenance pixels (values 7-9) are currently estimated to meet the site condition Endpoints in the GCPO LCC’s draft Integrated Science Agenda (v4). Enhancement pixels (values 4-6) are those that are currently classified as Upland Hardwoods (Forest) but do not meet the site condition Endpoints in the Science Agenda. Restoration pixels (values1-3) are those that are currently...
The alligator gar (Atractosteus spatula; AG) is a large, long-lived, physostomous fish that prefer slow-moving rivers, bayous, and oxbows most of the year, and require access to inundated floodplains or wetland vegetation for spawning and nursery habitats (Inebnit 2009; Kluender 2011, Buckmeier 2013). Historically, AG were distributed throughout the central U.S., ranging from Oklahoma southward to the Gulf of Mexico but more recently, abundances have declined and AG is now considered vulnerable to localized extirpation (Ferrara 2001) . Several authors have cited habitat alteration and overexploitation as the most important factors in the pervasive decline in abundance (Robinson and Buchanan 1988; Simon and Wallus...

Draft 2 of the summary report for ecological assessment of estuarine tidal marsh systems along the GCPO LCC Gulf Coast subgeography. This includes an assessment of landscape endpoints identified by the GCPO Adaptation Science Management Team in the draft GCPO LCC Integrated Science Agenda.The estuarine tidal marsh priority system in the Gulf Coastal Plains and Ozarks LCC (GCPO LCC) Integrated Science Agenda (ISA) includes general ecological systems of brackish/saltwater marsh and seagrass beds and was adopted as one of two initial ecological systems of focus for the Gulf Coast subgeography of the GCPO LCC (the other being beaches and dunes). The desired ecological state for Gulf Coast estuarine tidal marsh is a...

The amount, configuration, and condition of grasslands, prairies, and savannas in the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative (GCPO LCC) was assessed at 30 meter spatial resolution. Each pixel was assigned a score based on a dichotomous decision tree evaluating the following: whether described as a grassland ecological system class, if not, whether potentially restorable to grassland, if grassland, whether dominated by native plants (prairie), whether in a patch >100 acres in size, and whether described as having any of four condition endpoints: vegetation height (> 1 meter), vegetation cover (> 80% herbaceous or < 20% shrub), tree density (< 10 trees per acre), and disturbance pattern...
