These datasets represent model results from Rabotyagov et. al. 2014. Cost-effective targeting of conservation investments to reduce the northern Gulf of Mexico hypoxic zone. Proceedings of the National Academy of Sciences. 111 (52): 18530-18535. The authors developed an integrated assessment model linking the water quality effects of cropland conservation investment decisions on the more than 550 agricultural subwatersheds that deliver nutrients into the Gulf of Mexico with a hypoxic zone model. The model was used to identify the most cost-effective subwatersheds to target for cropland conservation investments. The 60% reduction [60PCT] model could cost-effectively reduce the area of the hypoxic zone to 5,000 km2,...
We found few reports in the literature containing useful data on the nesting phenology of lesser prairie-chickens; therefore, managers must rely on short-term observations and measurements of parameters that provide some predictive insight into climate impacts on nesting ecology. Our field studies showed that prairie-chickens on nests were able to maintain relatively consistent average nest temperature of 31 °C and nest humidities of 56.8 percent whereas average external temperatures (20.3–35.0 °C) and humidities (35.2– 74.9 percent) varied widely throughout the 24 hour (hr) cycle. Grazing and herbicide treatments within our experimental areas were designed to be less intensive than in common practice. We determined...

Mississippi River Basin Gridded SSURGO mapunits where "pwsl1pomu" (wetland potential) is at least 60 or at least 50 and "drclassdcd" (Drainage Class - Dominant Condition) is poorly or very poorly drained. These mapunits represent those with the highest wetland potential based on these criteria.

Areas identified in the Minnesota Pheasant Action Plan to target habitat enhancement and protection in complexes at least 9 square miles in size where a goal of 40 percent permanent protection can be met within the timeframe of the plan. The complexes identify the best places for pheasant production and focused protection efforts on those areas to create permanent habitat complexes. Ranking of the complexes was based on current conditions. For instance, if a complex is at 38% permanent protection, it scores very high since with only a little effort 40% protection can be achieved, conversely. A place that was 20% scored low. The complexes identify the best places for pheasant production and focused protection efforts...

This dataset is made up of features aggregated from Ecoregional Assessments as well as other planning methodologies used across The Nature Conservancy to identify areas of biodiversity significance and prioritize conservation action. More information about ecoregional assesments and other conservation planning methodologies is available at The Nature Conservancy's Conservation Gateway, the Ecoregional Assessment Status Tool (EAST), and at http://maps.tnc.org. This dataset provides a vision for conservation success for ecological systems, natural communities and species representative of an ecoregion by showing the boundaries of areas that The Nature Conservancy has prioritized for conservation within the Mississippi...

This dataset represents the soil water storage capacity (AWS in mm at 1.5 m depth) from SSURGO and STATSGO soil descriptions for soil map units in the state of southern Alaska that lie within the North Pacific Landscape Conservation Cooperative. Available Water Storage 0-150 cm - Weighted Average (centimeters). Available water storage (AWS). The volume of water that the soil, to a depth of 150 centimeters, can store that is available to plants. It is reported as the weighted average of all components in the map unit, and is expressed as centimeters of water. AWS is calculated from AWC (available water capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity)...

The USGS and South Atlantic LCC worked with stakeholders and managers across the Southeast to identify and assess landscape-level strategies for conserving multiple species. These strategies incorporated predictions from downscaled climate models, sea level rise, and changes to aquatic and terrestrial habitats.

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...

The project will use baseline data on pre-restoration measures of baseline hydrology and water quality to evaluate the impacts of large scale wetland and prairire restorations on hydrology and water quality including: recovery of key habitats and functions; abilities of wetlands to buffer variable water flows; ability of groundwater to buffer water flows; groundwater and surface water quality; changes in groundwater movement; rates of denitrification and carbon storage/ transport.
Although it is certain that climate change will affect the hydrology and biota of Great Plains streams, how and where these effects will be manifested is not known. This project will predict the effects of climate change on these streams by creating watershed hydrology and fish assemblage models that are both linked to watershed characteristics, then predicting changes resulting from climate change using an ensemble of general circulation models. We will identify the areas of primary conservation concern by calculating Index of Biotic Integrity values for 1,600 samples in an existing regional fish database and compare them to the areas that are most likely to experience change under future climate scenarios.

The concept of adaptive management provides a set of good business principles to guide strategic habitat conservation, but these principles are only useful if they are put into practice through a complimentary set of business operations. To that end, if conservation is going to be successful operating at landscape scales, the conservation community must start thinking and functioning like a conservation enterprise. Much more emphasis must be placed on developing and supporting business operations that facilitate the flow of information and other resources at landscape scales. Just like successful national and global businesses, we need to develop an information supply chain to support the communication, coordination,...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...
Working within the constraints of the SWAP revision timeline, we propose to advance biodiversity conservation within the region by enhancing the regional effectiveness of SWAPs and the ability of the LCC to address regional biodiversity priorities. We propose to accomplish these outcomes through engagement of SWAP coordinators and LCC professionals in the creation of a set of detailed best practices and learning resources tailored to needs that they help to identify. We will regularly engage with the SWAP coordinators as we develop these resources to allow each state to influence and employ the resources as needed, recognizing that time and resources to participate in this project will vary among states. As part...
