These data represent the forecast saturated thickness of the Ogallala aquifer in 2050 based on the linear rate of depletion calculated previously. Using the model-based annual predictions of aquifer saturated thickness (described above), we built annual water-level transition matrices (e.g., Turner, 1987) that were then projected out through 2050.

An urgent problem that we, the Caribbean conservation community, need to address is how best to allocate scarce resources to conservation initiatives directed at cays. Caribbean cays are both culturally and ecologically valuable, but are highly vulnerable to climate change, sea level rise, invasive species, and human uses, including recreational and residential development. In terms of climate change impacts and sea level rise, a few low-lying coralline and mangrove cays have already become partially or completely submerged such as one in the area of Guayanilla, Puerto Rico, monitored by the US Fish and Wildlife Service (USFWS) from 1991 until it’s submergence in 2004. Five species of seabirds and shorebirds that...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

Loss and fragmentation of grassland habitat can influence populations of the animal communities dependent upon this ecosystem. Grassland birds have faced notable declines in some areas of their range, potentially a result of changes to suitable habitat. Managing populations of grassland birds requires an understanding of the effects of habitat loss and fragmentation at a local and regional scale. We studied two grassland-dependent bird species, Eastern Meadowlarks (Sturnella magna) and Northern Bobwhites (Colinus virginianus), in an area of recent explosive growth in oil and gas related development. First, we quantified habitat lossand fragmentation of grassland habitat using remotely sensed datasets at multiple...
This project helps the Central Valley Joint Venture (CVJV) track gains and losses of key bird and waterfowl habitats at a landscape scale. This will allow the CVJV to effectively monitor and evaluate habitats essential to conservation planning for wildlife species. This work is important for identifying, assembling, and analyzing data for key habitats of concern and will provide a foundation for future monitoring.

Natural protected areas are geographic spaces clearly defined and delimited through legal or other effective means for the long-term conservation of their natural resources, biodiversity, ecosystem services and associated cultural values. This GIS file provides the latest compilation (as of the 15th of December of 2015) of the natural protected areas of Puerto Rico. This dataset includes all protected areas owned and managed or co-managed for the conservation of nature and natural resources by the following agencies and organizations: Puerto Rico Department of Natural and Environmental Resources (DRNA), Para la Naturaleza, US Forest Service, US Fish and Wildlife Service, National Oceanic and Atmospheric Administration...

This appendix presents detailed proceedings of the Caribbean Landscape Conservation Cooperative (CLCC): Deriving Shared Objectives Workshop held on June 3-4, 2015 and June 9-10, 2015 (hereafter referred to as the “CLCC SDM Workshop”).CLCC SDM Workshop discussions and products for each of the four days are summarized below. Detailed information can also be found on the workshop webpage at the CLCC website (click here).
This project integrates a reforestation decision support model for priority forest breeding birds and a restoration decision support tool for the federally-threatened Louisiana Black Bear. It was developed specifically to focus habitat restoration projects on frequently flooded agricultural lands within priority portions of the delta of Arkansas, Louisiana, and Mississippi, which were funded primarily by the Walton Family Foundation in 2010, 2011, 2012 and 2013.
This project will expand the East Gulf Coastal Plain’s existing grassland bird habitat model for prioritizing habitat management to include non-avian species of conservation concern in theGulf Coastal Plains and Ozarks region. It will also incorporate non-biological economics and cost effectiveness objectives into the decision framework.
Long-term, large-scale (i.e. landscape) conservation struggles with big questions such as how can a single strategy be identified when there are multiple possible future outcomes? How do we decide which management action or portfolio of actions is the best for all species when different species will likely have conflicting responses to each action? Successful natural resource decision making processes also incorporate an assessment of baseline conditions; current and future stressors; a set of potential management actions; and formal linkages between conditions, actions and biological responses (i.e. a model). It also requires bringing together the elements of conservation decisions into a framework that allows...
St. Catherine Creek NWR, outside of Natchez, MS is part of the Lower Mississippi River floodplain and provides valuable aquatic and upland habitats for a large diversity of both terrestrial and aquatic organisms. Federal and state fisheries managers both recognize the importance of this floodplain habitat as an integral part of the large river ecosystem and many state partners have crafted management plans that seek to promote conservation activities that enhance and preserve this important resource. The frequency, timing and duration of Mississippi River flooding, drives the spatial extent of floodplain inundation which in turn determines habitat quality and suitability of floodplain habitats for both aquatic and...
This request is in support of the Southeast Natural Resource Leaders Group (SENRLG) Landscape Conservation and Restoration Pilot Project. Phase I of the study was completed with support from UNC Asheville’s National Environmental Modeling and Analysis Center (NEMAC) in June 2011 after working closely with the SENRLG Pilot Project Team in October 2010. The first phase identified federal resources available for supporting ecological, cultural, and sociological resource protection across the Southeast within an adaptive framework for building resilience into the system to address risk climate change impacts on the landscape. To further define the co-benefits of leveraging resources in a synergistic manner on the landscape,...

These data represent the amount of crane energy days derived from croplands that are available within a 10km distance. These data were calculated by reclassing the NASS Cropland Data Layer to reflect energetic carrying capacity for cranes reported by Johnson et. al 2017. I.e Winter Wheat: 2588 CEDs/ ha, Corn: 1034 CEDs / ha, Sorghum: 496.5 CEDs / ha. A 10km moving windows analysis with a circular window was applied to the resulting CED raster to sum the CED values within a 10km area.

These data represent the long term average (27 year) amount of crane energy days (CED) available in wetlands. CEDs were calculated in the same way as wetland duck energy days describe above except that different habit energy density values were used. Based on the PLJV waterbird plan (2008) Appendix A, we estimated wetland CED density values for wetland habitats by dividing energetic carrying capacities for waterfowl by 3.37 to reflect the difference in mean body mass between mallards and sandhill cranes.
