High-latitude regions are experiencing rapid and extensive changes in ecosystem composition and function as the result of increases in average air temperature. Increasing air temperatures have led to widespread thawing and degradation of permafrost, which in turn has affected ecosystems, socioeconomics, and the carbon cycle of high latitudes. Research shows that the distribution of permafrost is heterogeneous in nature and that permafrost responds to a wide range of ecological factors. Here we overcome complex interactions between surface and subsurface conditions to map near-surface permafrost using decision-tree models, field observations, remotely sensed and derived data, and climatic indices. The resultant dataset...

States do maintain some level of information regarding the consumptive use of water by various sectors. This information is not regularly updated unless the information is mandated due to an ongoing environmental concern, state agreement, or compact. Many states who do estimate this category of water information release the information on an annual or multi-year basis. The period of record for consumptive water use is specific to each agency and their adopted program. Because of the variability between methods and the spatial and temporal disparity between states, this is a highly specific set of information. Consumptive use of water is a target dataset for the WSWC's Water Data Exchange (WaDE) program, and all...

States maintain databases that store water allocations, their owners, priority dates, legal status, and beneficial use categories. State water rights information is usually updated on an ad-hoc and ongoing basis. Some states issue quarterly updates to share their information with the public. Others have searchable database interfaces on their websites. The period of record for water rights information is as far-reaching as the agency itself. All states gather water allocation information, but western states use the prior appropriation doctrine to ensure the water is put to beneficial use. Water rights are a target dataset for the WSWC's Water Data Exchange (WaDE) program, and all states that are interested in sharing...

States maintain some records concerning places where water is withdrawn (points of diversion) and also some information about the amount of water that is withdrawn over time. They may also track specific diversions within a water right by its designated beneficial use category. States' diversion data can be updated on an ad-hoc basis or it may be subject to reporting requirements and be reported/recorded on a more set timeframe. The time that the information is updated internally varies and is specific to each agency's mission. Most states maintain this information in a database format. Water diversions are a target dataset for the WSWC's Water Data Exchange (WaDE) program, and all states that are interested in...

In 2006, the Century Commission for a Sustainable Florida called for an identification of those lands and waters in the state that are critical to the conservation of Florida's natural resources. In response, the Florida Natural Areas Inventory, University of Florida Center for Landscape Conservation Planning, and Florida Fish & Wildlife Conservation Commission collaborated to produce CLIP - the Critical Lands and Waters Identification Project. CLIP is now being used to inform planning decisions by the Peninsular Florida Landscape Conservation Cooperative, coordinated by the U.S. Fish and Wildlife Service.

Cutthroat trout (CT; Oncorhynchus clarki ssp.) are extremely imperiled owing to a variety of stressors. Changing climate is adding to these stressors that have already relegated CT in the Southern Rocky Mountains to less than 35% of their native habitat. The Rio Grande CT (O. c. virginalis) occupies 12% of its native range and is currently under review for ESA listing as federally threatened. Changing thermal regimes, hydroclimate, and disturbance regimes will continue to alter the remaining habitat of Rio Grande CT. An understanding the status and trends of Rio Grande CT thermal habitats and the vulnerability of these habitats to climate driven changes in temperature and stochastic disturbance regimes would enable...

Up to 12 different prey fish species were sampled with a 12-m bottom trawl during April, July, and September along two Lake Huron transects (Thunder Bay, Hammond Bay). At each transect in each month, two replicate 10-min tows were conducted at each of three depths (18, 46, 82 m) during the day and night. Once the fish were onboard in a given tow, they were sorted to species, weighed (in aggregate), and up to 50 individuals per species were measured to the nearest total length.

The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater...

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the Driftless Area Restoration Effort. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the boundary of the Driftless Area Restoration Effort. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled;...

A hydrologic model was developed as part of the Southeast Regional Assessment Project using the Precipitation Runoff Modeling System (PRMS), a deterministic, distributed-parameter, process-based system that simulates the effects of precipitation, temperature, and land use on basin hydrology. Streamflow and other components of the hydrologic cycle simulated by PRMS were used to inform other types of simulations such as water-temperature, hydrodynamic, and ecosystem-dynamics simulations.

Changes to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons were mapped for over 22,000 km of coastline along the Bering Sea and Gulf of Alaska coasts in western Alaska. Changes to rivers and lakes near the coast were also captured. The analysis was based on time-series analysis of Landsat imagery, 1972–2013. An annual time-series of suitable Landsat imagery was compiled and analyzed for changes in near-infrared reflectance to identify areas that transitioned from land to water, or vice-versa, over the study period. The timing of changes was also identified. Thousands of coastal changes over the 42-year study period exceeded the 60-m pixel resolution of the...

These files were used to construct corridors estimating the extent of new coastal corridors exposed by reduced lake levels. They are included here to show the available horizontal extent of lidar-derived topo-bathymetric data and thus explicitly identify gaps and limitations of predicted corridor extents under various reduced lake level scenarios. In addition, these files provide users with a background layer that depicts the topographic variability of the submerged near-shore lake bed and terrestrial landscape.These files are 5m grid representations of the hydrographic and topographic data collected by the CHARTS system along the coasts of the U.S. sides of Lake Michigan, Lake Huron, Lake St. Clair, Lake Erie,...
