Estimated number of breeding pairs of Bobolink based on the amount of grass, trees, and/or hay in the landscape. Landscape scale varied from 1/4- to 2-mile radius depending on the species. Pair estimates were calculated for grass patches >=1 ha, extrapolated to 40-ac cells, then smoothed by averaging over a 1-mile radius. Models were based on point count surveys conducted in 2003-2005 throughout the Tallgrass Prairie Pothole Region. Point count locations were stratified by cover type, the amount of grass in the landscape, and USFWS Wetland Management District boundaries. Landcover data were derived from 2000 Thematic Mapper imagery. Grid values = number of breeding pairs per 30-m pixel.

Mississippi River Basin Gridded SSURGO mapunits with at least 5% organic matter (generalized calculation using soil organic carbon values in the 0-20 cm horizon; assuming that bulk density is 1.4 g/cubic meter and that organic matter is 58% carbon).

Mississippi River Basin Gridded SSURGO potential wetland soil landscapes (PWSL version 1) - the percentage of the map unit (all components) that meet the criteria for a potential wetland soil landscape. For version 1 (pwsl1), those soil components that meet the following criteria are tagged as PWSL and their comppct_r values are summed for each map unit. Soil components with hydricrating = 'YES' are considered PWSL. Soil components with hydricrating = “NO” are not PWSL. Soil components with hydricrating = 'UNRANKED' are tested using other attributes, and will be considered PWSL if any of the following conditions are met: drainagecl = 'Poorly drained' or 'Very poorly drained' or the localphase or the otherph data...

Conservation estate and conservation priority areas identified by states, joint ventures, NGO’s, etc. within the greater Mississippi River Basin. NOTE: While the data layers “Sum - Conservation Focus Areas (2016)” and “Sum - Conservation and Watershed Interests (2016)” include conservation opportunity areas delineated by Louisiana DWF, this map service does not include that layer separately due to data sharing restrictions.

Designated Topeka Shiner Critical Habitat - Iowa Wildlife Action Plan (2007). This habitat is essential for the conservation of the Topeka Shiner and may require special management and protection. All indicated areas designated as critical habitat are occupied by the species or are short segments that provide critical links between habitats.

This layer summarizes the Mid-South Terrestrial Broadly Defined Habitats Condition Index based on Condition Index Scores alone. Some users may be interested in the scores generated by the project and their habitat management implications. The symbology and map colors in this dataset represent that information. For descriptions of existing and potential habitat and per-pixel habitat condition and landscape configuration inputs to these scores, consult the Mid-South Terrestrial Broadly Defined Habitats Condition Index with Barcode data layer, for which the map colors describe existing Broadly Defined Habitats.

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....

Some species respond to environments directly related to altitudinal variation. Elevation (e.g., DEM) is easily implemented in spatial modeling by limiting the model to the minimum and maximum values explicitly stated in the literature. DEMs are utilized directly and are measured in meters above mean sea level. The elevation dataset was derived from the National Elevation Dataset, elevation units are reported in meters. For more information regarding the National Elevation Dataset, see http://ned.usgs.gov/. This is a continuous data layer. These data are divided into 6 regions across the US (Northwest, Southwest, Great Plains, Upper Midwest, Southeast, and Northeast). If you want complete coverage of the entire...

The Potential Reforestation Index geospatial data product is a companion to the Forest Retention Index product from the Mapping the South’s Forests of the Future project. The Retention Index describes the likelihood that existing forests will remain in a forested condition at decadal time steps through 2060. The Potential Reforestation Index describes the likelihood that a non-forested land unit will be converted to forest cover at those same time steps. We used two datasets to determine areas currently occupied by agriculture that may be most conducive to reforestation efforts: National Commodity Crop Productivity Index (NCCPI) and Potentially Restorable Wetlands on Agriculture Land (PRWAg). The NCCPI is available...

The Blueprint provides planners and managers across organizations the opportunity to align their efforts to protect fish and wildlife habitat, improve quality of life for people, and develop strong economies. The Blueprint includes assessments of future land use change, including sea level rise and urban growth projections, to assist in shaping a more resilient landscape and a sustainable future for natural resources in Florida. The Blueprint will continue to be refined in the future as new/improved data become available. The Blueprint can be used for decision support to: -Prioritize conservation actions/investments -Plan for natural disasters -Develop incentive programs -Increase success in securing grant funds...

Large forest blocks are important features on the landscape and worthy of conservation attention. Maintenance of large blocks of intact habitat is perhaps the most oft recommended biodiversity conservation strategy. We created a map of large forest blocks by selecting all of the forest formations from the Ecological Systems dataset and converting this raster coverage into a polygon coverage using ArcMap. We then used the area function within the resulting attribute table to calculate areas of forest habitats across the state. Last, we classified them according to parameters originally developed by the Orange County Open Space Plan (Orange County Planning Department, 2004) and further utilized by Cornell University’s...

This dataset represents the North Atlantic LCC's ecoregion boundary. Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.

Conservation priority ranks and threat metrics for each drainage catchment in the Lower Colorado River Basin. Catchments are the drainage area (local watersheds) for each individual stream segment within the 1:100,000 scale National Hydrography Plus Version 1 (NHDPlusV1) dataset. Catchments are assigned conservation priority ranks (C_ConsVal) between 0 - 1 with 1 being the highest priority.

This is a land cover dataset for Nebraska that was most recently updated in 2015 by the Rainwater Basin Joint Venture. This metadata record supplements the complete description of the data in Bishop, A., Barenberg, A., Volpe, N., and Grosse, R. January, Nebraska Land Cover Development Version 11. Rainwater Basin Joint Venture, U.S. Fish and Wildlife Service, Grand Island, Nebraska.

“Bird Conservation Regions (BCRs) are ecologically distinct regions in North America with similar bird communities, habitats, and resource management issues. They are based on the scale-flexible hierarchical framework of nested ecological units delineated by the Commission for Environmental Cooperation (CEC). These ecoregions encompass areas that are similar in their biotic (e.g., plant and wildlife) and abiotic (e.g., soils, drainage patterns, temperature, and annual precipitation) characteristics. BCRs may be partitioned into smaller ecological units when finer scale conservation planning, implementation, and evaluation are necessary. Conversely, BCRs may be aggregated to facilitate conservation partnerships throughout...
