Taken from the DMP: "Georeferencing of plots and determination of site conditions using GIS. Accuracy of plot abundance values assessed with vegetation maps, satellite imagery, and expert consultation. Ten native and five invasive species of trees, shrubs and ferns were selected based on their potential ecological importance in communities, as well as how much field data was available to analyze for this study. For baseline climate condition variables, we used surface temperature and rainfall estimates (30 year baseline period, 1978–2007) developed by Giambelluca et al. (2013) with grid cell resolution of 250m. To estimate climate change responses, we used future projected climate variables developed by the International...
A summary data set of all fire polygons we could locate as of December 2007. We used multiple datasets to develop this layer including data gathered from the internet, publically available databases, and personal contacts with dozens of agency personnel throught the western U.S. Data were assessed for utility (but not accuracy) and formatted for consistency. Each source data set was then attributed consistently with fields for record number and year (of fire). Because various resource management entities map fires somewhat independently (especially in more recent years) we merged overlapping polygons for each year. Users are encouraged to understand the contents of this data file before using it.

The Virginia Natural Landscape Assessment (VaNLA) was a landscape-scale GIS analysis that identified, prioritized, and linked important lands to form natural land networks throughout Virginia. Using land cover data derived from satellite imagery, the VaNLA identified large, unfragmented cores, patches of natural land with at least 100 acres of interior cover. Cores provide habitat for a wide range of species, from interior-dependent forest species to habitat generalists, as well as for species that utilize marsh and maritime habitats. The most ecologically significant cores were linked by landscape corridors. Lower-ranked cores and fragments of natural land that intersected landscape corridors were added as corridor...

Reaches on the USEPA 303d list of impaired waterways where causes and sources are from agriculture nutrients within the Mississippi River Basin. Source: http://www.epa.gov/waters/data/rad_303d_20140804_fgdb.zip. Downloaded May 2015.

A GIS-based analysis was used to model habitat connectivity in the three Okanagan Regional Districts in British Columbia: the North Okanagan Regional District, the Central Okanagan Regional District and the Regional District of Okanagan-Similkameen. This model integrated a series of parameters to identify connected and potentially fragmented habitats. The model was not specific to a particular species. The goal was to identify portions of the landscape offering a higher opportunity for wildlife movement at a regional scale. The following parameters were used to model connectivity corridors: Elevation – Lower elevations (i.e., the valley) receive higher scores; Slope – Steep slopes receive lower scores; Terrain Ruggedness...

A subset of the EPA/Omernick Level III High Plains Ecoregion (25) that was selected as a pilot landscape conservation design project.

This ranking criterion was developed to identify those pits that most negatively impact watershed integrity of publically owned and Wetland Reserve Program (WRP) playa wetlands. Currently, the U.S. Fish and Wildlife Service (USFWS) manages 59 Waterfowl Production Areas (WPAs) while the Nebraska Game and Parks Commission oversees 35 Wildlife Management Areas (WMAs). These wetlands flood as a result of precipitation or snow melt. With the transition to pivot irrigation, a large number of irrigation reuse pits have been abandoned over recent years. Although not being used for irrigation, these pits continue to fill with water from precipitation events shortstopping water that could have reached the neighboring...

This representation of Montana's conservation district boundaries is based on boundary descriptions obtained from legal descriptions filed with the Conservation Districts Bureau of the Department of Natural Resources and Conservation. This data shows the outer boundaries of the 58 districts, although there may be some land within the boundaries that are excluded from some conservation districts.� For specific information, contact the local conservation district. Conservation districts are units of local government designed to help citizens conserve their soil, water, and other renewable natural resources. In 1937, President Roosevelt encouraged all states to adopt legislation enabling the creation of local soil...

The purpose of this map is to provide a georeferenced characterization of vegetation in the early stages of Euro-American settlement. One of the research uses for the surveys nationally is for presettlement vegetation. This data can be used to analyze presettlement vegetation patterns for the purpose of determining natural community potential, productivity indexes, and patterns of natural disturbance. The area of the original plat maps were townships; use of the data at a larger scale would not be appropriate.In Illinois, the surveys began in 1804 and were largely completed by 1843. The surveyors moved across the state laying out a rectangular grid system, known as the Public Land Survey System (PLS or PLSS). They...

Areas identified in the Minnesota Pheasant Action Plan to target habitat enhancement and protection in complexes at least 9 square miles in size where a goal of 40 percent permanent protection can be met within the timeframe of the plan. The complexes identify the best places for pheasant production and focused protection efforts on those areas to create permanent habitat complexes. Ranking of the complexes was based on current conditions. For instance, if a complex is at 38% permanent protection, it scores very high since with only a little effort 40% protection can be achieved, conversely. A place that was 20% scored low. The complexes identify the best places for pheasant production and focused protection efforts...

This dataset is made up of features aggregated from Ecoregional Assessments as well as other planning methodologies used across The Nature Conservancy to identify areas of biodiversity significance and prioritize conservation action. More information about ecoregional assesments and other conservation planning methodologies is available at The Nature Conservancy's Conservation Gateway, the Ecoregional Assessment Status Tool (EAST), and at http://maps.tnc.org. This dataset provides a vision for conservation success for ecological systems, natural communities and species representative of an ecoregion by showing the boundaries of areas that The Nature Conservancy has prioritized for conservation within the Mississippi...

Conservation priorities have been identified for each river basin at the cataloging unit or stream reach scale and were categorized using two tiers to indicate relative importance when considering the limited resources available for conservation initiatives. The recommendations were developed by Commission biologists through review of their field data as well as data from several agencies and research organizations. The review considered a combination of factors such as the presence of federal- or state-listed species; distribution of priority species; high species diversity; unique habitats, or high-quality habitats in the subbasin; and the importance of the watershed to downstream populations. Priority areas identified...

In 2006, the Century Commission for a Sustainable Florida called for an identification of those lands and waters in the state that are critical to the conservation of Florida’s natural resources. In response, the Florida Natural Areas Inventory, University of Florida Center for Landscape Conservation Planning, and Florida Fish & Wildlife Conservation Commission collaborated to produce CLIP - the Critical Lands and Waters Identification Project. CLIP is now being used to inform planning decisions by the Peninsular Florida Landscape Conservation Cooperative, coordinated by the U.S. Fish and Wildlife Service.

Priority resources are the set of biological, ecological, and cultural features and ecological processes collaboratively identified as most important, and are the focus of the PFLCC’s planning and scientific efforts. These are based on the draft set of priority resources established by the first Conservation Target Working Group of the PFLCC. The priority resources established in this working group are as follows: coastal uplands, cultural, estuarine, freshwater aquatic, freshwater forested wetlands, freshwater non-forested wetlands, hardwood forested uplands, high pine and scrub, landscape connectivity, marine, pine flatwoods and dry prairie, and working lands. The majority of these priority resources are based...
