The LANDFIRE existing vegetation layers describe the following elements of existing vegetation for each LANDFIRE mapping zone: existing vegetation type, existing vegetation canopy cover, and existing vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery, biophysical gradient layers, and classification and regression trees.DATA SUMMARY: The existing vegetation type (EVT) data layer represents the current distribution of the terrestrial ecological systems classification developed by NatureServe for the western Hemisphere (http://www.natureserve.org/publications/usEcologicalsystems.jsp). A terrestrial ecological system is defined as a group...

Green River Basin boundary. From the National Coal Resource Assessment. The assessment identifies and characterizes the coal beds and coal zones that will provide the bulk of the Nation's coal-derived energy during the next few decades.

This layer represents areas which have been proposed (per the requirements of Section 368 of the Energy Policy Act of 2005) as West-wide energy corridors for the final "Programmatic Environmental Impact Statement, Designation of Energy Corridors on Federal Land in the 11 Western States", November 2008. The layer was intersected with surface management agency, BLM field office, and state layers to add more tabular attributes.

Vegetation and land cover of Blue Ridge National Wildlife Refuge, circa 2011. This dataset is based on interpretation of aerial imagery from the National Agricultural Imagery Program from 2010. Image classification was performed using eCognition software, which creates homogeneous polygons from the imagery. Image statistics such as texture, NDVI and spectral values were then calculated for each polygon used to classify the imagery. Field data was collected in August, 2011 to assist in the image interpretation. No additional field data were collected for validation, and no validation or accuracy assessment was completed for this dataset. Therefore, no estimates of accuracy are given.

The main objective of this project was to develop a dataset of large, anthropogenic barriers that are spatially linked to the National Hydrography Dataset Plus Version 1 (NHDPlusV1) for the conterminous U.S. and the high resolution National Hydrography Dataset (NHD) for Alaska (1:63,000 scale) and Hawaii (1:24,000 scale) to facilitate GIS analyses based on the NHDPlusV1/NHD and NID datasets. To meet this objective, Michigan State University conducted a spatial linkage of the point dataset of the 2009 National Inventory of Dams (NID) created by the U.S. Army Corps of Engineers (USACE) to the NHDPlusV1/NHD. The pool of dam data included were modified based on 1) dam removals that occurred after development of the...

The National Conservation Easement Database (NCED) is a collaborative venture to compile easement records (both spatial and tabular) from land trusts and public agencies throughout the United States in a single, up-to-date, sustainable, GIS compatible, online source. The goal of the NCED is to provide a comprehensive picture of conservation easement lands, recognizing their contribution to America's natural heritage, a vibrant economy, and healthy communities. Conservation easements are legal agreements voluntarily entered into between landowners and conservation entities (agencies or land trusts) for the express purpose of protecting certain societal values such as open space or vital wildlife habitats. In some...

This dataset is a compilation of forest insect, disease and abiotic damage mapped by aerial detection surveys on forested areas in the United States. At this time, the National Aerial Survey Data Standards require only mortality and defoliation data be collected and reported. However, many cooperators collect data on other types of damage and therefore, the national database has been designed to accommodate these data. Low-level flights, typically 1,000 to 2,000 feet above ground level, are used to map forest damage. Observers use paper maps, typically 1:100,000 scale USGS maps, upon which they record the damage. There is also a digital sketchmap system that may be used. The digital system uses GPS to display the...

Data was digitized from original scribe sheets used to prepare the published Geologic Map of Wyoming (Love and Christiansen, 1985), consequently at a 1:500,000 scale.

This map layer includes agricultural minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey. The mineral operations are plants and (or) mines surveyed by the MIT and considered currently active in 2003. This is a replacement for the June 2004 map layer.

This file contains geologic faults within the southern Wasatch Plateau study area. The Nation's coal resources are being reassessed by the USGS. This assessment identifies and characterizes the coal beds and coal zones that will provide the bulk of the nation's coal-derived energy during the next century. This assessment is different from previous large-scale USGS assessments because files and databases are being stored in a digital format and are being analyzed using a Geographic Information System (GIS).

The Great Plains Landscape Conservation Cooperative (GPLCC, http://www.greatplainslcc.org/) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support wildlife...

These layers were produced as part of the WGA/LCC Riparian Mapping Project, which identified riparian location, condition, and climate adaptation potential, for the Pacific Northwest, USA. These layers identify potential riparian areas (i.e., near-stream valley bottoms; Theobald et al. 2013) that span large temperature gradients, have high canopy cover, low solar insolation, and low levels of human modification – characteristics expected to facilitate climate-induced species range shifts and provide micro-climatic refugia from warming. Detailed description of the project rationale, methods, and resulting layers may be found in Krosby et al. (2014). References: Krosby, M., Norheim, R., Theobald, D. M., and B. H....
