This indicator depicts the number of different stream size classes in a river network not separated by large dams. Reason for Selection River networks with a variety of connected stream classes help retain aquatic biodiversity in a changing climate by allowing species to access climate refugia and move between habitats. Input Data – Estimated Floodplain Map of the Conterminous U.S. from the EPA EnviroAtlas (see this factsheet for more information) – Other input for this indicator was provided by the Southeast Aquatic Connectivity Assessment Project (SEACAP). SEACAP identifies this metric within the category of “size/system type”. It measures the number different stream size classes in each functional network. To...

Systematic conservation planning is well suited to address the many large-scale biodiversity conservation challenges facing the Appalachian region. However, broad, well-connected landscapes will be required to sustain many of the natural resources important to this area into the future. If these landscapes are to be resilient to impending change, it will likely require an orchestrated and collaborative effort reaching across jurisdictional and political boundaries. The first step in realizing this vision is prioritizing discrete places and actions that hold the greatest promise for the protection of biodiversity. Five conservation design elements covering many critical ecological processes and patterns across the...

The model was acquired from Tyler Wagner (U.S. Geological Survey) (DeWeber & Wagner, 2014). Model outputs were composed of Ecological Drainage Units (EDUs), each of which was assigned a resulting mean predicted occurrence probability. The study region was determined by the Eastern Brook Trout Joint Venture (EBTJV) and represents the native range of the species on the East Coast. The polygons of interest were derived from the NHD plus dataset, with local catchments located at least 90% within the study region boundary. Presence data was taken from fish sampling records collected from state agencies and the Multistage Aquatic Resources Information System (MARIS), and these points were joined to the nearest stream...

Hellbender presence data was acquired from NatureServe and limited to points dating from 1980 to the present, with individual points adapted from the available data. Geospatial data was acquired from the U.S. Geological Survey’s National Land Cover Database (NLCD) and the Horizon Systems Corporation National Hydrography Dataset (NHD) Version 2. The study was conducted over the extent of the Appalachian LCC. Environmental variables of consideration were determined through literature review and expert advice on the species (Personal correspondence, Quinn, 2009). Hellbender presence data was sub-sampled to reduce spatial bias. Pseudo-absence points were also calculated to be within 1 km of the position of the presence...

Abstract To aid in parameterization of mechanistic, statistical, and machine learning models of hydrologic systems in the contiguous United States (CONUS), flow-conditioned parameter grids (FCPGs) have been generated describing upstream basin mean elevation, slope, land cover class, latitude, and 30-year climatologies of mean total annual precipitation, minimum daily air temperature, and maximum daily air temperature. Additional datasets of upstream basin area and binary stream presence-absence are provided to help validate queries against the flow-conditioned data. These data are provided as virtual raster tile (vrt) mosaics of cloud optimized GeoTIFFs to allow point queries of the data (see Distribution Information)...

The Arkansas MAV Conservation Delivery Network serves to link the fundamental planning and design functions of the Lower Mississippi Valley Joint Venture partnership with the delivery programs of conservation partners by establishing a forum for cooperative coordination, leveraging, and targeting of their actions on-the-ground. The Delivery Priority Tool for the AR-MAV CDN is an model overlay that stacks (or combines) Ducks Unlimited's Wetland Restoration Suitability Model for the MAV, the Forest Breeding-bird Reforestation Decision Support Model for the MAV created by the LMV Joint Venture, and Ducks Unlimited's Easement Protection Priority Model for the MAV. The Tool then takes the upper tier(priority values...

The purpose of this data set is support resource allocation decisions (i.e. where to invest conservation effort) within the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative. The Condition Index ranks pixels (250-m) according to how well they meet the Desired State for the Open Pine habitat system, which is described qualitatively and quantitatively in the GCPO LCC’s draft Integrated Science Agenda (v4). Higher values indicate sites closer to the Desired State. Value of 1 indicates areas appropriate for restoration but currently under an alternative land use (i.e. potential habitat). Please see PDF file in the Open Pine folder in the Blueprint Gallery at https://gcpolcc.databasin.org/ for a full...

This data represents an assessment of forest patch size used in the ecological assessment of upland hardwood systems by the GCPO LCC. We used a combination of remote sensing products including 2011 National Land Cover Database (NLCD) forest classes and the 2011 MAV forest classification layer produced by the Lower Mississippi Valley Joint Venture to delineate patches of all forest types in the GCPO LCC. We used NLCD as the primary data source when assessing forests outside the GCPO LCC MAV subgeography, and the LMVJV forest classification as the primary data source for forest assessment within the MAV. NLCD was developed using 2011 Landsat TM imagery, with forest classes including only areas with trees exceeding...

This dataset has been archived; it has been superseded by version 2.0 (November 2021) which can be found at https://doi.org/10.5066/P95PT2RV. Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and water depth of shoreline flooding in 8 segments corresponding...

The REA estimates the condition of 14.2 million acres of land in southern New Mexico. It is based on states described in “ecological site descriptions” (ESDs) and expert knowledge. ESDs have been developed by the Natural Resource Conservation Service, and they are a consistent, science and expert-based resource increasingly used by land managers. It focuses on public rangelands - grasslands, shrublands, and savannas - managed by the Bureau of Land Management, and includes some other lands as well. The REA compares current condition to the expected or “reference” condition, and summarizes the vegetation, ecological processes and restorative management options of these states. Depending on these management options...

Priority and use segments for Sandhill Cranes (Antigone canadensis). Segments designated as use areas were utilized during annual spring surveys 2014-2016. Priority areas were determined using statistical modeling. The reduced model that best predicted use by Sandhill cranes included total area of trees, pits, crops and unvegetated sandbar habitats in each segments. Mean distance to conservation lands and roads and minimum distance to transmission lines and towers were also included in the model. Only distance to lines and total tree area had a significant (p < 0.05) relationship with priority core segments.
