4KM grid cell reporting units for the Sonoran Desert Ecoregion Used as analytical reporting unit for terrestrial conservation elements and terrestrial intactness.
eBird collects observations from birders through portals managed and maintained by local partner conservation organizations. In this way eBird targets specific audiences with the highest level of local expertise, promotion, and project ownership. Portals may have a regional focus (aVerAves, eBird Puerto Rico) or they may have more specific goals and/or specific methodologies (Louisiana Winter Bird Atlas, Bird Conservation Network eBird). Each eBird portal is fully integrated within the eBird database and application infrastructure so that data can be analyzed across political and geographic boundaries. For example, observers entering observations of Cape May Warbler from Puerto Rico can view those data separately,...
The California Department of Transportation (Caltrans) and California Department of Fish and Game (CDFG) commissioned the California Essential Habitat Connectivity Project because a functional network of connected wildlands is essential to the continued support of Californias diverse natural communities in the face of human development and climate change. The Essential Connectivity Map depicts large, relatively natural habitat blocks that support native biodiversity (Natural Landscape Blocks) and areas essential for ecological connectivity between them (Essential Connectivity Areas). This coarse-scale map was based primarily on the concept of ecological integrity, rather than the needs of particular species. Essential...

Difference of Runoff simulated by the biogeography model MAPSS using RegCM3 climate with GFDL projections as boundary conditions. Units are millimeters of water. MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid (http://www.databasin.org/climate-center/features/mapss-model). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation) as well as soils information (texture, depth). Based on a set of climatic thresholds,...

This dataset presents the current potential distribution of Lucy's Warbler within the context of current and near-term terrestrial intactness and long-term potential for energy development and potential for climate change (4KM reporting units). Current terrestrial intactness is based on current measures of landscape development, fire regime and vegetation impacts, and fragmentation. Near-term intactness includes estimates of urban growth and expansion of invasive vegetation. Long-term potential for energy development is based on areas of potential for wind, solar, and petroleum development derived from multiple sources. Long-term potential for climate change is based on absolute changes in runoff, precipitation,...
The TIGER/Line Shapefiles are an extract of selected geographic and cartographic information from the Census MAF/TIGER database. The Census MAF/TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each TIGER/Line Shapefile is designed to stand alone as an independent data set or the shapefiles can be combined to cover the whole nation.
This dataset represents survey points for the Asian clam (Corbicula fluminea ) surveyed by the National Parks Service, Aquatics Invasive Species Project in the Sonoran Desert ecoregion.

The RMU_UNIT feature class depicts the boundaries of the range allotments, general resource areas, and wild horse and burro territories on the Tonto National Forest and is part of the USFS Southwestern Region Core Data Project. This project is designed to generate and maintain 15 vertically integrated resource data layers which are standardized across the Southwestern Region.

This database contains GIS datasets representing the distribution of mule deer habitat throughout the United States and Canada (Alberta and Saskatewan only). Mule deer habitat is divided into 6 separate GIS layers corresponding to 6 types of mule deer habitat: 1)limited range, 2) summer range, 3) other important habitat, 4) winter range, 5) winter concentration, and 6) year-round population. Information on mule deer limiting factors associated with each habitat type is provided within the GIS datasets. Habitat delineations were identified through a Delphi process on a state-by-state basis and were subsequently tablet-digitized from 1:250,000 scale maps.
This dataset shows special designations (polygon features) compiled from the CBI Protected Areas Database (May 2011 with interim updates), Roadless Areas, National Conservation Easements Database (August 2011), BLM NLCS Wilderness Areas (2011), and BLM ACECs (2011). This dataset was updated to fix an erroneous assignment of a single polygon from Other to Wilderness Area. This dataset contains wilderness areas, wilderness study areas, national parks, national monuments, and several other designations.
