Total Basal Area (BA) for all tree species is in square feet per acre.To monitor the potential hazards posed by invasive pathogens, the U.S. Forest Service’s Forest Health Technology Enterprise Team (FHTET) created a national database designed to assess the potential hazards on tree mortality and identify forest ecosystems at risk of invasive or pathogenic threats.When the introduction or increased activity of invasive or pathogenic plant and animal species dramatically alters the structure and function of ecosystems, the benefits that those ecosystems provide to people are also affected. Additionally, the negative effects of forest pathogens and invasives on certain species may be exacerbated by climate change,...

Using GIS, the SILVIS Lab at the University of Wisconsin-Madison calculated housing and population counts at the block group level with data from the decennial U.S. Census to produce a spatially explicit dataset for the conterminous U.S. This data can help to understand where on the landscape the most and the least dense populations of people live. Housing density can be used as an indicator of urbanization and land-use intensification.

Streamflows in late spring and summer have declined over the last century in the western U.S. and mean annual streamflow is projected to decrease by six to 25% over the next 100 years. In arid and semi-arid regions of the western US, it is likely that some perennial streams will shift to intermittent flow regimes in response to climate-driven changes in timing and magnitude of precipitation, runoff, and evaporation. The project will address the following two research question: how will small stream (1st-3rd order) low flow hydrology be impacted by predicted longer, drier summers in the Upper Colorado River Basin under climate change and in turn, what will be the resulting impacts on riparian plant communities?...

About This Project Open woodlands dominated by southern yellow pine were historically a large component of the landscape across the southeastern United States. These woodlands have an open canopy of longleaf, slash, shortleaf, and/or loblolly pines, with scattered shrubs and a grassy understory. These southern open pine ecosystems support many species of wildlife, many of which have declined in recent years as the amount and condition of their habitat has declined. This troubling decline in wildlife species has led to a focus on regional conservation efforts by America’s Longleaf, the National Fish and Wildlife Foundation, Landscape Conservation Cooperatives, state wildlife agencies, the U.S. Forest Service, National...

Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors, including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity, all of which are accelerated by climate change. This dataset represents the geographic boundary of the Appalachian LCC.

Regional Climate Centers (RCC) Palmer Drought Severity Index (PDSI: drought index). Recent 10-year climatology for drought in all months, 1950-1999.Drought is one of the most consequential aspects of variation in precipitation and temperature patterns in terms of its impacts on natural ecosystems and human systems. The production of food and clean water can be strongly affected, as can forest products production, outdoor recreation, ecosystem processes such as wildland fire, and many other processes affecting ecosystem services. Having a grasp on recent ranges of variability in drought conditions can provide a context for understanding ongoing and future climate change and its impacts on ecosystem services. Although...

The Urban Influence measure developed by the U.S. Department of Agriculture (USDA) Economic Research Service (ERS) identifies metropolitan counties by population size and outlines where natural area and urban boundaries exist. This can help to indicate where increased stresses on ecosystem services may occur.The boundaries between urban, rural, and natural areas in Appalachia are increasingly defined by the accelerated demand for ecosystem services from growing urban populations. Increases in “urbanness” not only stress the capacity of affected landscapes to provide ecosystem services, but also magnify the pressure on nearby natural areas to provide those services to more people. However, opportunities exist for...

The proposed project focuses upon two major goals:1. Designate Priority Amphibian and Reptile Conservation Areas (PARCAs) in the South Atlantic Landscape, and develop an adaptive management plan for those areas.2. Determine whether PARCAs provide an effective strategy for integrated, long-term conservation of biodiversity and cultural resources in the South Atlantic Landscape; and develop a comprehensive biodiversity protection plan for the SALCC.To achieve these goals, we have identified the following objectives:Objective 1. Identify areas within the SALCC that are vitally important to preserving the rich diversity of amphibians and reptiles in the region, focusing upon rare species distribution, diversity, and...

Without reliable spatial data for wetland and riparian areas, it is impossible for land managers to accurately assess the distribution of critical aquatic habitats and model potential impacts caused by climate change. Wetlands in the Southern Rockies are particularly important for wildlife habitat, as they are often far more productive than the surrounding uplands. In addition, wetlands are an integral component of regional hydrologic cycles through their role in flood abatement, storm water retention, groundwater recharge, and water quality improvement.Colorados wetlands were mapped by the FWS early 1980 and in late 1990, and though the maps exist, they were created for print and most are not useful as digital...

Efforts to model and predict long-term variations in climate, based on scientific understanding of climatological processes, have grown rapidly in their sophistication to the point that models can be used to develop reasonable expectations of regional climate change. This is important because our ability to assess the potential consequences of a changing climate for particular ecosystems or regions depends on having realistic expectations about the kinds and severity of change to which a region may be exposed.The fifth phase of the Coupled Model Intercomparison Project (CMIP5) is a collaborative climate modeling research effort coordinated by the World Climate Research Programme (WCRP).This is the most recent phase...

The model for golden-winged warbler was acquired from Dolly Crawford (Ashland University), which was included in Chapter 3 of the 2012 conservation plan (Roth et al., 2012). Model was composed of cells of predicted Golden-Winged Warbler occurrence across the study region. The study region was determined by the expert opinion derived by the technical team regarding the core breeding populations of Golden-Winged Warbler presence and assigned to the Great Lakes Conservation Region and Appalachian Conservation Region. Within these areas, certain extents are recommended for Golden-Winged Warbler conservation, as they are priority species in those regions and do not promote the invasion of Blue-Winged Warbler, a known...

Forest cores are derived by applying an inverse buffer (-100m) to forest patches to represent the area of contiguous interior forest habitat. Forest patches are defined as areas of contiguous natural cover bound by non-natural edge or linear fragmenting features (roads, railroads, transmission lines, natural gas pipelines). The following land cover types were selected from the 2006 National Land Cover Database (NLCD) to define “natural cover”: deciduous forest, coniferous forest, mixed [deciduous-coniferous] forest, scrub-shrub, woody wetland, and emergent wetland. Forest patches were delineated based on non-forest edge (from the NLCD) and the following linear fragmenting features:electric transmission lines (from...

This dataset features inundated areas connected to the main channel at discharges from 15,000 cfs to 95,000 cfs. The spatial extent for floodplain inundation modeling in the lower Trinity River was from Romayor, Texas, to approximately Moss Bluff, Texas. River sections were modeled using steady flow conditions. For the upper section, discharge and stage were both available for the two gages (Romayor USGS 08066500 and Liberty USGS 08067000). For the lower section, the Moss Bluff gage (USGS 08067100) is tidally-influenced, so gage height didn’t correspond to upstream changes in discharge. To model river stage specific inundation for the upper section, discharge for each Landsat 8 overpass date was entered as the upstream...

Developed by the Oak Ridge National Laboratory (ORNL), the LandCast 2050 High-Resolution Population Projection models future national-level human population densities. The models estimate the probability of a population being at a particular location, which measures where people will likely be in the future, not necessarily their places of residence.The LandCast 2050 data set is an empirically-informed spatial distribution of projected population of the contiguous U.S. for 2050 compiled on a 30” x 30” latitude/longitude grid. Population projections of county level numbers were developed using a modified version of the U.S. Census’ projection methodology-with the U.S. Census’ official projection as the benchmark....
