Extent and approximate location of historic wetland habitats in Indiana, Iowa, and Wisconsin. Partial state coverage in Minnesota and South Dakota. NWI data last updated as of 1 May 2016. Data accessed 11 July 2016.

Bottomlands of large rivers within the Mississippi River Basin. Derived by combining the Mississippi alluvial plain with natural floodplains created by the Scientific Assessment and Strategy Team for the Upper Mississippi, and statewide floodplain coverages where available. While the Mississippi alluvial plain is not entirely bottomland (e.g. Crowley's Ridge), excluding these non-bottomland areas from analysis would exclude opportunities to expand existing forest patches and enhance connectivity. NOTE: Floodplain coverage in Arkansas, Louisiana, Mississippi, and Missouri is incomplete due to incomplete data availability as of October 2016.

Mississippi River Basin Gridded SSURGO Hydric Classification – Presence "hydclprs". An indication of the proportion of the map unit that is hydric, based on the hydric classification of individual map unit components.

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...

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...

Sum of all conservation focus areas (CFA) for a particular area (UPDATED TO INCLUDE CONSERVATION PRIORITIES DELINEATED IN LATEST STATE WILDLIFE ACTION PLANS (ca. 2015/2016)). These focus areas include both those delineated at the state scale as well as regionally. States focus areas are included for all states in the Mississippi River Basin that have delineated focus/opportunity areas. States that are not included either have not delineated focus areas or were in the process of developing them at the time of data collection. States where CFA are pending: Texas and Wyoming. States where CFA have not been identified: Georgia; Maryland; Michigan; New Mexico; New York; and Oklahoma. Regional focus area include those...

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.

Forest restoration opportunities in large river bottomlands, Mississippi River Basin. NOTE: Floodplain coverage in Arkansas, Louisiana, Mississippi, and Missouri is incomplete due to only partial data availability as of October 2016.

Estimated number of breeding pairs of Grasshopper sparrow 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.

Predictions of the number of upland nesting duck pairs (mallards, blue-winged teal, gadwall, northern pintail, and northern shoveler) that could potentially nest in the upland habitats of every 40 acre block of the Prairie Pothole Region (PPR). These predictions are based on the known maximum travel distances of hens from wetlands to their nest sites, and regressions (statistical models) created from 4 square mile survey data predicting the number of duck pairs that utilize every individual wetland in PPR during a “typical” breeding season. GRID CODE = Number of Duck Pairs: 1 = 0-10; 2 = 11-20; 3 = 21-40; 4 = 41-60; 5 = 61-80; 6 = 81-100; 7 = >100.
