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.

Estimating species abundance is important for land managers, especially for monitoringconservation efforts. The two main survey methods for estimating avian abundance are point counts and transects. Previous comparisons of these two methods have either been limited to a single species or have not included detection probability. During the 2012 breeding season, we compared and assessed the efficiency (precision for amount of effort) of point count time of detection (PCTD) and dependent double-observer transect (TRMO) methods based on detection probabilities and abundance estimates of five species of songbirds that use a range of habitats in a prairie system in Montana dominated by sagebrush and grassland vegetation....

The habitats and food resources required to support breeding and migrant birds dependent on North American prairie wetlands are threatened by impending climate change. The North American Prairie Pothole Region (PPR) hosts nearly 120 species of wetland-dependent birds representing 21 families. Strategic management requires knowledge of avian habitat requirements and assessment of species most vulnerable to future threats. We applied bioclimatic species distribution models (SDMs) to project range changes of 29 wetland-dependent bird species using ensemble modeling techniques, a large number of General Circulation Models (GCMs), and hydrological climate covariates. For the U.S. PPR, mean projected range change, expressed...

Conservation planning aims to optimize outcomes for select species or ecosystems by directing resources toward high-return sites. The possibility that local benefits might be increased by directing resources beyond the focal area is rarely considered. We present a case study of restoring river connectivity for migratory fish of the Great Lakes Basin by removing dams and road crossings within municipal jurisdictions versus their broader watersheds. We found that greater river connectivity could often be achieved by considering both intra-jurisdictional and extra-jurisdictional barriers. Focusing on jurisdictional barriers alone generally forfeited <20 (median = 0%) of habitat gains for those who value solely habitat...

Identifying the climatic drivers of an ecological system is a key step in assessing its vulnerability to climate change. Theclimatic dimensions to which a species or system is most sensitive – such as means or extremes – can guide methodologicaldecisions for projections of ecological impacts and vulnerabilities. However, scientific workflows for combining climateprojections with ecological models have received little explicit attention. We review Global Climate Model (GCM)performance along different dimensions of change and compare frameworks for integrating GCM output into ecologicalmodels. In systems sensitive to climatological means, it is straightforward to base ecological impact assessments onmean projected...

Oil development in the Bakken shale region has increased rapidly as a result of new technologies and strongdemand for fossil fuel. This region also supports a particularly high density and diversity of grassland bird species,which are declining across North America. We examined grassland bird response to unconventional oilextraction sites (i.e. developed with hydraulic fracturing and horizontal drilling techniques) and associatedroads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development,as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 150 m of roads(95% CI: 87–214 m), 267 m of single-bore well pads (95% CI: 157–378 m),...

Many waterbird species utilize a diversity of aquatic habitats; however, with increasing anthropogenic needs tomanage water regimes there is global concern over impacts to waterbird populations. The federally threatened pipingplover (Charadrius melodus; hereafter plovers) is a shorebird that breeds in three habitat types in the Prairie PotholeRegion of North Dakota, South Dakota, and Canada: riverine sandbars; reservoir shorelines; and prairie wetlands. Watersurface areas of these habitats fluctuate in response to wet–dry periods; decreasing water surface areas exposeshorelines that plovers utilize for nesting. Climate varies across the region so when other habitats are unavailable forplover nesting because of flooding,...

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.

NRCS Common Resource Areas (CRA), version 1.2. 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. Features have been conflated with land cover attributes pertinent to the MRB/GHI e.g. cropland, forest, prairie, etc.

The Greater Sage Grouse Focal Area represents an area of interest pertaining to the greater sage grouse under the U.S. Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) Working Lands for Wildlife (WLFW) Wildlife Habitat Incentive Program (WHIP).Working Lands for Wildlife is a partnership between NRCS and the U.S. Fish and Wildlife Service (FWS) to use agency technical expertise and financial assistance from the Wildlife Habitat Incentive Program to combat the decline of seven specific wildlife species whose decline can be reversed and will benefit other species with similar habitat needs. The WLFW project will target species whose decline can be reversed and will benefit other species...

There is mounting concern that climate change will lead to the collapse of cyclic population dynamics, yet the influence of climate variability on population cycling remains poorly understood. We hypothesized that variability in survival and fecundity, driven by climate variability at different points in the life cycle, scales up from local populations to drive regional characteristics of population cycling and spatial synchronization.
