Low-lying areas (1-acre minimum) within the MRB/GHI Water Quality Priority Zone derived from 30-m NED DEM Topographic Position Index (180-m radius) values less than 1/4 standard deviation below the mean. Used as an aid in identifying wetland restoration potential.

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of sagebrush ecosystem to climate change and resistance/resilience for each 12-digit hydrologic unit. Using a vulnerability framework, we defined Sensitivity (S) as the multi-scale average of sagebrush ecosystem land cover derived from LANDFIRE Existing Vegetation Type (LANDFIRE 2014). Exposure (E) to climate change was based on the max-normalized value of climate velocity from AdaptWest (2015). Potential Impact (PI) is the square root transformed product of climate change exposure and sagebrush ecosystem sensitivity. Adaptive Capacity (AC) of sagebrush ecosystem to climate change was based on soil and landform...

Annual raster-based maps of LULC conditions for the years 1938 to1992 were created based on information on historical patterns and prescriptions of LULC change. The intent of these historical LULC projections was not to recreate exact past LULC conditions, but to provide useful maps of simulated historical land-cover for use in secondary analysis. The baseline LULC condition was derived from a modified version of the 1992 National Land Cover Dataset (http://www.epa.gov/mrlc/nlcd.html). Historic data and others were used to guide a spatially explicit (FOREcasting SCEnarios of land-cover change) land-cover forecasting model in allocating LULC change distributions on the landscape, based on logistic regression analysis...

Landfire v.1.2.0 Biophysical Setting within the Mississippi River Basin. The Biophysical Settings (BpS) layer represents the vegetation that may have been dominant on the landscape prior to Euro-American settlement and is based on both the current biophysical environment and an approximation of the historical disturbance regime.

Estimated number of breeding pairs of Bobolink 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.

Mississippi River Basin Gridded SSURGO mapunits with at least 5% organic matter (generalized calculation using soil organic carbon values in the 0-20 cm horizon; assuming that bulk density is 1.4 g/cubic meter and that organic matter is 58% carbon).

Mississippi River Basin Gridded SSURGO potential wetland soil landscapes (PWSL version 1) - the percentage of the map unit (all components) that meet the criteria for a potential wetland soil landscape. For version 1 (pwsl1), those soil components that meet the following criteria are tagged as PWSL and their comppct_r values are summed for each map unit. Soil components with hydricrating = 'YES' are considered PWSL. Soil components with hydricrating = “NO” are not PWSL. Soil components with hydricrating = 'UNRANKED' are tested using other attributes, and will be considered PWSL if any of the following conditions are met: drainagecl = 'Poorly drained' or 'Very poorly drained' or the localphase or the otherph data...

Conservation estate and conservation priority areas identified by states, joint ventures, NGO’s, etc. within the greater Mississippi River Basin. NOTE: While the data layers “Sum - Conservation Focus Areas (2016)” and “Sum - Conservation and Watershed Interests (2016)” include conservation opportunity areas delineated by Louisiana DWF, this map service does not include that layer separately due to data sharing restrictions.

Designated Topeka Shiner Critical Habitat - Iowa Wildlife Action Plan (2007). This habitat is essential for the conservation of the Topeka Shiner and may require special management and protection. All indicated areas designated as critical habitat are occupied by the species or are short segments that provide critical links between habitats.

The Human Modification (HM) model is designed to provide a comprehensive, but parsimonious approach, that uses several stressor/threats datasets to estimate level of human modification. There are three important elements that define the HM approach: (a) the human modification stressors and their data sources (b) the measurement unit used for each stressor, and (c) the method used to combine the effects of multiple stressors into an overall score of human modification. The way in which these various data layers are combined into a single index is quite important. We use a method that minimizes bias associated with non-independence among several stressor/threats layers (Theobald 2013). The HM model assumes the contribution...

Green infrastructure networks designed by The Conservation Fund for areas within the Mississippi River Basin. These green infrastructure networks were developed using the core-hub-corridor approach as follows. The building blocks of the network are “core areas” that contain well-functioning natural ecosystems that provide high-quality habitat for native plants and animals. By contrast, “hubs” are aggregations of core areas as well as nearby lands that contribute significantly to ecosystem services like clean water, flood control, carbon sequestration, and recreation opportunities. Finally, “corridors” are relatively linear features linking cores and hubs together, providing essential connectivity for animal, plant,...
