River Conservation Opportunity Areas represent areas of the state where organizations and individuals working on the conservation of SGCN and their habitat would be most likely to successfully implement the conservation actions summarized in the Wildlife Action Plan for taxonomic and natural community groups. Providing information to help people make decisions about “where” to implement conservation actions is an important related aspect of conservation actions. Although most COAs have been given boundaries, they are indeed “fuzzy”, meaning their application can vary considerably according to context or conditions and they are not fixed or definitive—they will move, depending on the objectives.

Conservation Opportunity Areas are places in Illinois: with significant existing or potential wildlife and habitat resources; where partners are willing to plan, implement, and evaluate conservation actions; where financial and human resources are available; and where conservation is motivated by an agreed-upon conservation purpose and set of objectives.To create a list of places in the state fitting this description, scientists with Illinois Natural History Survey identified priority areas for conservation, using a variety of tools, such as Audubon’s Important Bird Areas and The Nature Conservancy’s portfolio sites. The centerpiece of their analyses, however, was a dataset showing the state’s key blocks of habitat...
The Wildlife Action Network is composed of mapped terrestrial and aquatic habitats, buffers, and connectors that represent a diversity of quality habitats that support Species in Greatest Conservation Need (SGCN). The Network is made up of mapped habitat representing viable or persistent populations and “richness hotspots” of Species in Greatest Conservation Need (SGCN). Added to this information are other data on the relative condition of habitat including spatially prioritized and connected Sites of Biodiversity Significance, Lakes of Biological Significance, and Streams with “exceptional” Indices of Biological Integrity. Consideration should be given to projects or activities that could result in the loss, degradation...

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.
Abstract (from http://www.nrcresearchpress.com/doi/abstract/10.1139/cjfas-2014-0517#.VSwd3Y7F8qZ): Seasonal degradation of aquatic habitats from hypoxia occurs in numerous freshwater and coastal marine systems and can result in direct mortality or displacement of fish. Yet, fishery landings from these systems are frequently unresponsive to changes in the severity and extent of hypoxia, and population-scale effects have been difficult to measure except in extreme hypoxic conditions with hypoxia-sensitive species. We investigated fine-scale temporal and spatial variability in dissolved oxygen in Lake Erie as it related to fish distribution and catch efficiencies of both active (bottom trawls) and passive (trap nets)...

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.
In the spring of 1996, a nine-day test flood from Glen Canyon Dam involved the deepest and largest hypolimnetic withdrawals from the penstocks and the river outlet works (ROW) since 1986, interacting with ongoing hydrodynamic and stratification patterns to enhance freshening of the hypolimnion of Lake Powell reservoir and its tailwaters. Prior to the test flood, a six-year drought had produced a pronounced meromictic hypolimnion that was weakening from high inflow events in 1993 and 1995. Hypoxia, however, had continued to increase in the deepest portions of the reservoir. Over the course of the test flood, 0.893 km3 were released from the ports located at and below the hypolimnetic chemocline. The increased discharge...

The U.S. Forest Service and USDA’s Natural Resources Conservation Service are working together to improve the health of forests where public and private lands meet. Through the Joint Chiefs’ Landscape Restoration Partnership, the two USDA agencies are restoring landscapes, reducing wildfire threats to communities and landowners, protecting water quality and enhancing wildlife habitat.

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.

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...
