For more information about how these data were developed, please see the final report. Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and more dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations for the species, are also defined. Note actual species population data to define the nodes is not used, as that data was often unavailable, and the focus is on the potential spread of the species across the SALCC region and not limited to models to known populations. Therefore, node locations were determined by...
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....
The balance between economic needs and natural resource conservation will become more tenuous in the future as a result of a myriad of environmental stressors. We propose a methodology that can help guide forest management practices whenever adequate species locational data and quality forest or land use data exist. More specifically, the results of this study can be used to evaluate alternative land and silviculture management scenarios in terms of creating or maintaining high-quality forest habitat for a specific species. We used data collected on radiotelemetered black bears from 1988 to 2015 to develop a regional habitat model throughout Louisiana and Arkansas using Mahalanobis distance (D2) statistic. We created...

This data product contains estimates of habitat quality for 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 ruggedness, topographic position index (TPI), road density, distance to water,...

BlackBearHumanConflict is an ESRI SDE Feature Class showing human/bear conflict areas for Black Bear (Ursus americanus) in Colorado. Human/bear Conflict Areas are defined as that portion of the overall range where two or more confirmed black bear complaints per season were received which resulted in Colorado Division of Wildlife investigation, damage to persons or property (cabins, tents, vehicles, etc.), and/or the removal of the problem bear(s). This does not include damage caused by bears to livestock. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard...
This report summarizes the results of a three-year investigation of terrestrial habitat connectivity priorities for the South Atlantic Landscape Conservation Cooperative (South Atlantic LCC). Our primary objective was to generate results that could be used to drive fineā€scaled conservation planning to enhance habitat connectivity across the South Atlantic LCC. The project focused on seven target species, including large mammals (black bear, red wolf, Florida panther/eastern cougar) and a group of terrestrial reptiles (eastern diamondback rattlesnake, timber rattlesnake, pine snake, and box turtle). We used two different modeling approaches to identify areas with either high predicted flow of a given species (Circuitscape)...

Black Bear movement corridor strenght predicted from a factorial least cost path analysis across a resistance map. This layer shows the major nodes through which large numbers of least cost routes pass. The areas of highest corridor intensity form a dendritic network showing the major linkages among portions of the analysis area

BlackBearFallConcentration is an ESRI SDE Feature Class showing fall concentration areas for Black Bear (Ursus americanus) in Colorado. Fall Concentration Areas are defined as those parts of the overall range that are occupied from August 15 until September 30 for the purpose of ingesting large quantities of mast and berries to establish fat reserves for the winter hibernation period. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing...

This data product contains estimates of habitat quality and connectivity for mountain lion, mule deer, desert bighorn sheep, and black bear, and combined estimates of high habitat and connectivity areas for all species. 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).

The Commission on Environmental Cooperation, in concert with a trinational group of experts, has identified North American species of common conservation concern (SCCC). These terrestrial and marine species comprise a group of important migratory, transboundary and endemic species selected from among the continent’s great wealth of wild flora and fauna, which require regional cooperation for their effective conservation.

The connectivity result files from Circuitscape represent the "adjusted cumulative current density" flowing across the landscape for each of several species, at a 90-meter resolution across the South Atlantic Landscape Conservation Cooperative region. Rasters are classified using quantiles with 20 categories (each 5% of region) to integer scores from 1-20. 1 = lowest 5% of the landscape, 20= top 5% of landscape Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations,...

This report presents the results of a harvest survey and ethnographic research project that investigated the subsistence uses of large land mammals and furbearers in Game Management Unit 25 in the Yukon Flats region of Interior Alaska. Large land mammal species harvested and used by Yukon Flats residents include moose Alces alces, caribou Rangifer tarandus, black bear Ursus americanus, and brown bear Ursus arctos. Furbearing species included in this study are marten Martes americana, lynx Lynx canadensis, and wolf Canis lupus. For the 2008–2009 study year a total of 284 of 467 households (approximately 61%) were surveyed in the 7 Yukon Flats communities of Beaver, Birch Creek, Chalkyitsik, Circle, Fort Yukon, Stevens...
