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.

Pilot Basins are HU-4 basins where there is an alignment of ecological and production systems of interest with areas thought to be producing significant agricultural nutrient loads and possessing significant implementation interests. These provisional basins represent areas of greatest opportunity in terms of need and potential for conservation delivery. Two tiers of pilot basins were identified for version 1.02 of the Conservation Blueprint. Tier 1 pilot basins have the highest nutrient load potential and the highest amount of watershed implementation interest, while Tier 2 pilot basins have either lower load potential or lower watershed implementation interest than Tier 1 pilot basins. Implementation opportunities...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

The NOAA Hypoxia Watch project provides near-real-time, web-based maps of dissolved oxygen in milligrams per liter (mg/L) near the sea floor over the Texas-Louisiana continental shelf during a period that extends from mid-June to mid-July. The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA National Coastal Data Development Center (NCDDC) at Stennis Space Center began the Hypoxia Watch project in 2001. Scientists aboard the NOAA Research Vessel Oregon II measure seawater properties, such as water temperature, salinity, chlorophyll, and dissolved oxygen at each of approximately 240 locations as the Oregon II cruises the waters south of Pascagoula,...

Conservation Opportunity Areas (COA) are intended to guide conservation activities at a landscape level. Landscape conservation is a developing theme across the country and throughout Indiana. Building off the successes of other Indiana landscape initiatives, like Goose Pond Fish and Wildlife Area and the Healthy Rivers Initiative, Indiana DFW has identified opportunities on the landscape to focus conservation efforts over the next decade. These COA were identified as a way to direct actions toward specific areas on Indiana’s landscape.

The Gridded SSURGO National Commodity Crop Productivity Index (NCCPI), version 2.0, arrays soils according to their inherent capacity to produce dryland (nonirrigated) commodity crops. Most of the NCCPI criteria relate directly to the ability of soils, landscapes, and climates to foster crop productivity. A few criteria relate to factors that can limit use of the land (e.g., surface boulders). All criteria used in the index affect crop culture and production and are referred to as factors affecting inherent productivity. Higher values represent higher capacity for production. Extent: Mississippi River Basin. IN ORDER TO CREATE A MANAGEABLE FILE SIZE, THE ORGINAL DATA WAS MULTIPLIED BY 100, THUS VALUES RANGE FROM...

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.

Sum of all watershed-based (HU-8) implementation interests or priorities identified as of June 2016 within the Mississippi River Basin. These watersheds represent areas identified as a focus for investment to improve either water quality or aquatic habitat. Data was compiled from state, federal, regional, and non-governmental organizations including, but not limited to USDA-NRCS, USEPA, USFWS, Fish Habitat Partnerships, Gulf Hypoxia Task Force, and State Nutrient Reduction Strategies. Some HUC-12 priority watersheds were included as well, but coded to the HUC-8 level. Data from the Mississippi River Basin Initiative, National Water Quality Initiative and State Nutrient Reduction Strategies were updated in 2016.

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.
The Gulf Coast Vulnerability Assessment utilized expert opinion that was gathered through the Standardized Index of Vulnerability and Value (SIVVA) tool, which is an Excel-based vulnerability and prioritization tool that enables assessors to provide input in a relatively short time and allows for relatively seamless compilation of results. The vulnerability of each ecosystem and associated species was conducted by subregion, excluding those subregions where the species did not occur in significant numbers. Assessors were asked to evaluate species based on the habitats they use in a particular subregion. Because vulnerability can vary with life-stage for many species, assessors were asked to consider the most vulnerable...
