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.It represents a relative ranking of HUC12 watersheds according to the quantity and quality of habitat as described in the GCPO LCC’s draft Integrated Science Agenda (v4). Watersheds (HUC12) were ranked by the presence, quantity and quality of the Forested Wetland habitat system (includes bottomland hardwoods, swamps and wet riparian forests) within the 5 sub-geographies of the GCPO LCC region. Once ranked, watersheds were classified (e.g., “Top 10%”) based on the proportion of the total Forested Wetland area (current + potential)...

This data product contains combined estimates of high habitat connectivity areas for mountain lion, mule deer, desert bighorn sheep, and black bear. The analysis area was a 236,000 square kilometers that encompassed the Navajo Nation, which includes portions of Arizona, New Mexico, and Utah. The estimates of habitat quality were created with spatially explicit habitat variables and either an expert-based linear combination process (for mountain lion and mule deer) or a generalized linear mixed model-based estimation that used radio-collar telemetry data (for desert bighorn sheep, black bear, and pronghorn; collected between 2005-2011). Habitat variables varied among species but included vegetation type, terrain...

Developed by the Oak Ridge National Laboratory (ORNL), the LandCast 2050 High-Resolution Population Projection models future national-level human population densities. The models estimate the probability of a population being at a particular location, which measures where people will likely be in the future, not necessarily their places of residence.The LandCast 2050 data set is an empirically-informed spatial distribution of projected population of the contiguous U.S. for 2050 compiled on a 30” x 30” latitude/longitude grid. Population projections of county level numbers were developed using a modified version of the U.S. Census’ projection methodology-with the U.S. Census’ official projection as the benchmark....

Basal area is a measure of the cross-sectional area of trees calculated by multiplying the foresters’ constant (0.005454) by the squared diameter of each tree to determine a measure of tree area (ft2 or m2) per unit area (acre or ha). Similar to an assessment of forest canopy cover, basal area provides a measure of horizontal structure, and is closely associated with measures of vertical structure. When assessing condition of upland hardwood woodland and forest systems, the GCPO LCC Integrated Science Agenda targets a large proportion of the basal area in those systems to be composed of oak and hickory species. This endpoint targets >90% of basal area as oak and hickory for upland hardwood woodland systems and >70%...

Our objective was to model frequency of low-pulse events on small, ungaged streams in the Upper Colorado River Basin. Modeling streamflows is an important tool for understanding landscape-scale drivers of flow and estimating flows where there are no gaged records. We focused our study in the Upper Colorado River Basin, a region that is not only critical for water resources but also projected to experience large future climate shifts toward a drier climate. We used a random forest modeling approach to model the relation between frequency of low-pulse events on gaged streams (115 gages) and environmental variables. We then projected frequency of low-pulse events to ungaged reaches in the Upper Colorado River Basin...

The National Cohesive Wildland Fire Management Strategy, initiated in 2009 and finalized in 2014, provides a national vision for wildland fire management. This highly collaborative effort establishes three overarching goals, and describes stakeholder-driven processes for achieving them: (1) resilient landscapes; (2) fire-adapted communities; and (3) safe and effective wildfire response. The scientific rigor of this program was ensured with the establishment of the National Science and Analysis Team (NSAT). The main tasks of NSAT were to compile credible scientific information, data, and models to help explore national challenges and opportunities, identify a range of management options, and help set national priorities...
