Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of species for population supplementation is often based on performance prior to release, and one or a few species may then be used for decades even as the environment is changing. When these species are propagated in large numbers, they can become the dominant population as well as genetically overtake any local adaptations. Therefore,...

Publicly available geospatial data were identified, collated, and analyzed for a region of karst terrain extending from Albany to Buffalo, New York. A series of geospatial datasets were assembled to determine the location and extent of karstic rock; bedrock geology and depth to bedrock; average water-table configuration; surficial geology; soil type, thickness, and hydraulic conductivity; land cover; and closed depressions in the land surface First release: 2021 Revised: July 2022 (ver. 2.0) Revised: October 2022 (ver. 3.0) Revised: January 2024 (ver. 4.0)

Small lakes are important to local economies as sources of water supply and places of recreation. Commonly, lakes are considered more desirable for recreation if they are free of the thick weedy vegetation, often comprised of invasive species, that grows around the lake edge. This vegetation makes it difficult to launch boats and swim. In order to reduce this vegetation, a common technique in the Northeast and Midwest U.S. is a ‘winter drawdown’ . In a winter drawdown, the lake level is artificially lowered (via controls in a dam) during the winter to expose shoreline vegetation to freezing conditions, thereby killing them and preserving recreational value of the lake. However, this practice can impact both water...

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Carlisle 30 x 60 minute quadrangle in Pennsylvania. The source data used to construct this imagery consists of 1-meter resolution lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2019 and 2020 and downloaded from the USGS National Map TNM Download. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984 Web Mercator. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.

The U.S. Geological Survey (USGS), in cooperation with the U.S. Fish and Wildlife Service (USFWS) and the U.S. Environmental Protection Agency (EPA), identified the occurrence of contaminants of emerging concern (CECs) in water and bottom sediment collected in 2013 at 57 sites throughout the Great Lakes Basin. The 2013 effort is part of a long-term study that began in 2010. Included in this directory are references to or descriptions of analytical methods used, collection methods, environmental data, and associated quality-assurance data for samples collected in 2013. Samples were collected from April through October 2013 by USGS, USFWS, and/or EPA personnel. Study sites include tributaries to the Great Lakes...

The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...
This data release includes a polygon shapefile of grid cells attributed with values representing the simulated base-flow, evapotranspiration, and groundwater-storage depletions as a percentage of hypothetical well pumpage for the 2011-2060 time period. Depletions were simulated by the Phase-Three Elkhorn-Loup Model (ELM), constructed using MODFLOW-NWT (Niswonger and others, 2011). Each polygon represents one model grid cell, with pumping specified from either layer one or layer two of the model. All values are estimates and approximations. The phase three ELM simulated the High Plains aquifer in north-central Nebraska from predevelopment (pre-1895) through 2060 (Flynn and Stanton, 2018). The simulation was calibrated...

Paper copies of chemical analyses made at Illinois State Geological Survey from approximately 1932 to 1995. Includes chemical analyses for approximately 30,000 coal samples, 20,000 rock samples, 5,000 gas samples, 5,000 brine samples, and 5,000 water samples.

These data represent trapping effort and captures of deer mice at Point Reyes National Seashore, Marin County, California. Deer mice were captured and marked with ear tags to allow identification of individuals. The location of captures can be used in a spatially explicit capture recapture model to estimate density of mice and how mouse density varies by site and habitat type.

North Cascades National Park, Washington. Glaciers at the head of Luna Creek in Picket Range. This complex of ice patches illustrates the difficulty of counting and classifying individual glaciers. A glacier fed by ice avalanches ends in Luna Lake on the left. Avalanches from the large irregular hanging glacier that clings to the cliffs feed the debris-covered ice upslope from another lake (foreground, right center). A small ice patch fed by snow avalanches lies at the base of the cliffs in right center. September 27, 1960. Plate 3-D, U.S. Geological Survey Professional paper 705-A. 1971.

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood management strategies are being implemented in urban areas, less is known about how tidal flooding, and associated inundation into surface and groundwater, might influence watershed dynamics and the native animals that depend on estuarine environments where freshwater meets the sea. Efforts for biocultural restoration of ecosystem...

Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...
