This dataset displays polygon data for Global Important Bird Areas in the Mississippi River Basin.From its start in Europe in the 1980s, the Important Bird Areas concept has been a success, leading to the recognition and protection of some 3,500 sites worldwide. American Bird Conservancy's Important Bird Areas Program was launched in 1995 and has concentrated on identifying and documenting the very top sites throughout all 50 states - those of significance on a global level. Many kinds of sites are represented: National Wildlife Refuges, National Parks and Forests, state lands, conservation organization lands, and some private lands. Some of these sites are important because they are links along a migratory pathway....

The Louisiana State Legislature created Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Pelican Island and Pass La Mer to Chaland Pass Resoration (BA-38) project for 2013. This data is used as a basemap habitat classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land...

This dataset consists of long-term (~65 years) shoreline change rates for the north coast of Alaska between Point Barrow and Icy Cape. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1947 and 2012. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate long-term rates.

This dataset includes shorelines from 65 years ranging from 1947 to 2012 for the north coast of Alaska between the Colville River and Point Barrow. Shorelines were compiled from topographic survey sheets (T-sheets; National Oceanic and Atmospheric Administration (NOAA)), aerial orthophotographs (U.S. Geological Survey (USGS), National Aeronautics and Space Administration (NASA), and lidar elevation data(USGS). Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change for the U.S. Geological Survey's National Assessment of Shoreline Change Project. Rates of long-term and short-term...

This layer represents land cover classes mapped within the Modoc Wildlife Refuge. Mapping was completed using a combination of field data, object-based image analysis using Feature Analyst, and photo interpretation. Source data included 2005 CIR NAIP digital aerial photography, and Modoc National Wildlife Refuge data layers. Field data was collected by USFWS staff in May and June of 2007.

Vegetation and land cover data for Upper Klamath NWR. This dataset is based on interpretation of 2014 near-infrared imagery produced by the National Aerial Imagery Program of the U.S. Department of Agriculture with input on the general vegetation composition provided by local refuge staff. Field data at the species level were not available and further work is needed to refine this product to meet the convention of the National Vegetation Classification System. In addition, no validation was performed on this dataset.

Conservation Opportunity Areas are places in Illinois: with significant existing or potential wildlife and habitat resources; where partners are willing to plan, implement, and evaluate conservation actions; where financial and human resources are available; and where conservation is motivated by an agreed-upon conservation purpose and set of objectives.To create a list of places in the state fitting this description, scientists with Illinois Natural History Survey identified priority areas for conservation, using a variety of tools, such as Audubon’s Important Bird Areas and The Nature Conservancy’s portfolio sites. The centerpiece of their analyses, however, was a dataset showing the state’s key blocks of habitat...
The Wildlife Action Network is composed of mapped terrestrial and aquatic habitats, buffers, and connectors that represent a diversity of quality habitats that support Species in Greatest Conservation Need (SGCN). The Network is made up of mapped habitat representing viable or persistent populations and “richness hotspots” of Species in Greatest Conservation Need (SGCN). Added to this information are other data on the relative condition of habitat including spatially prioritized and connected Sites of Biodiversity Significance, Lakes of Biological Significance, and Streams with “exceptional” Indices of Biological Integrity. Consideration should be given to projects or activities that could result in the loss, degradation...

River Conservation Opportunity Areas represent areas of the state where organizations and individuals working on the conservation of SGCN and their habitat would be most likely to successfully implement the conservation actions summarized in the Wildlife Action Plan for taxonomic and natural community groups. Providing information to help people make decisions about “where” to implement conservation actions is an important related aspect of conservation actions. Although most COAs have been given boundaries, they are indeed “fuzzy”, meaning their application can vary considerably according to context or conditions and they are not fixed or definitive—they will move, depending on the objectives.

The GIS shapefile "Census summary of southern sea otter 2016" provides a standardized tool for examining spatial patterns in abundance and demographic trends of the southern sea otter (Enhydra lutris nereis), based on data collected during the spring 2016 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies. This Shape file includes a series of summary statistics derived from the raw census...

The subset of all NRCS Common Resource Areas (CRA), version 1.2, that can support native prairie habitats within the Mississippi River Basin. A Common Resource Area is defined as a geographical area where resource concerns, problems, or treatment needs are similar. It is considered a subdivision of an existing Major Land Resource Area (MLRA) map delineation or polygon. Landscape conditions, soil, climate, human considerations, and other natural resource information are used to determine the geographic boundaries of a CRA.

In order to identify areas within the Mississipi River Basin (MRB) where implementing wildlife conservation actions could potentially provide the highest benefit to both local waters and the Gulf of Mexico the Miss. River Basin/Gulf Hypoxia Initiative identified a "Water Quality Priority Zone". This provisional zone of interest represents HUC-8 watersheds having the highest potential for nutrient export from agricultural sources (using nitrogen as a surrogate). The potential for nutrient export was determined using the 2002 SPARROW Mississippi/Atchafalaya River Basin Model and cropland data from the 2013 USDA-NASS Cropland Data Layer. As the results from the SPARROW model are somewhat dated (ca. 2002), we incorporated...
