This coverage contains arcs representing the sailing line for the center of the navigation channel for the Upper Mississippi River, that is maintained by the Corps of Engineers.

This represents historical reference conditions for old tallgrass and wet prairie areas. Thus, offers information toward ecological land management efforts.These data represent the areas that the US GLO land surveyors and French/Spanish surveyors considered to be prairie in Missouri.

This shape file represents an ecological boundary for the Crown of the Continent Ecosystem (CCE) as defined by the Crown Managers Partnership (CMP). The CMP developed the boundary through a series of meetings held in 2008, including a meeting between the CMP and non government organizations working in the Crown on July 23, 2008. The purpose of this exercise was to develop an ecological justification for the CCE, to enable analysis and tracking of the ecosystem from an ecological health perspective. The CMP notes that this extent does not represent the true economic, social and cultural impact on the CCE from surrounding urban areas. In Alberta the eastern boundary was delineated by the Foothills Fescue Subregion...

The broadly shared information needs for grassland managers in the North Central region to meet conservation goals in a changing climate are presented and ranked as highly relevant, somewhat relevant, or not relevant for federal, state, tribal, and non-governmental grassland-managing entities.

This shapefile represents habitat suitability categories (High, Moderate, Low, and Non-Habitat) derived from a composite, continuous surface of sage-grouse habitat suitability index (HSI) values for Nevada and northeastern California during summer¸ which is a surrogate for habitat conditions during the sage-grouse brood-rearing period.

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...

Nitrogen (N) and phosphorus (P)-related impaired waters for which a TMDL has been developed (Cycle Year 2010) within the Mississippi River Basin. For purposes of identifying N/P-related TMDLs, EPA used the following national impairment categories: algal growth, ammonia, noxious aquatic plants, nutrients, organic enrichment/oxygen depletion.

This item has two datasets which provide information over the entire CCE: 1. MPB_AB_5kmBuffer_2000.shp: Mountain Pine Beetle (MPB) disturbance in the Alberta portion of the Crown of the Continent Ecosystem from 2001 to 2007. This layer is a compilation from multiple sources.These data are used to help focus ground survey work and are not 100% accurate. 2. MPB_CCE_5kmBuffer_2000: This layer represents polygons within and up to 5km outside the British Columbia and Montana portions of the Crown of the Continent Ecosystem with groupings of dead (red) pine trees which indicate a high likelihood of green attack mountain pine beetle trees from 2001 to 2007. The current beetle year (August 15 to August 15) Mountain Pine...

Previous research identified species of invasive plants in Hawai'i which are highly flammable and act as fuels in wildfires across Hawai'i. This work aimed to map the distribution of these species (largely grasses) around the islands of Hawai'i with the goal of using the locations for species distribution modeling. All data represents presence data, no absence data were recorded. Data are largely from within the past 20 years, but some georeferenced herbarium specimens go as far back as 1905. Data were obtained from georeferenced herbarium specimens, vegetation plot data, citizen science data (iNaturalist) reviewed by the authors, and data from roadside surveys conducted as part of this research to map these species....

Dataset contains locations of drainage tile permits in North Dakota obtained from the State Water Commission as of October 2013. This dataset provides the latitude and longitude of the location given on the permit, which is not provided by the State Water Commission database. Additionally, overlap of permit polygons (if depicted in a geospatial application) is possible from two permits that share the same area. Permit applications that were marked as denied or that did not require a permit as determined by the State Water Commission were removed from this database.

Ducks Unlimited CPC (Conservation Program Committee) approved focus areas for conservation easements and land acquisitions within the Mississippi River Basin. These regions are very important to DU's habitat restoration and enhancement.Focus areas are designated by DU Board for acquiring conservation easements and land acquisitions without going through three board committees for approval. Only DU's internal board reviews any new easements or acquisitions in focus areas.

Areas in which Ducks Unlimited wants to do the bulk of their conservation work - restorations, enhancements, and protection (acquisitions/easements) within the Mississippi River Basin. The data was last updated on May 10, 2013. The Platte River LCP boundary was changed to include Big Thompson Ponds SWA.

This digital version of the original vegetation cover map can be used to identify regional changes in land cover since the time when the state was first surveyed. This data is not intended for landscape-scale analysis.This is a polygon shapefile derived from a 1:500,000-scale map showing the original, pre-settlement vegetation cover in Wisconsin. The original vegetation cover data was digitized from a 1976 map created from land survey notes written in the mid-1800s when Wisconsin was first surveyed. Linework representing lakes and other hydrographic areas in other data sets were subsequently merged with the original vegetation cover data set to more closely match the source map.

This shapefile represents habitat suitability categories (High, Moderate, Low, and Non-Habitat) derived from a composite, continuous surface of sage-grouse habitat suitability index (HIS, created using ArcGIS 10.2.2) values for Nevada and northeastern California during spring, which is a surrogate for habitat conditions during the sage-grouse breeding and nesting period.
