Science Analytics and Synthesis (SAS)
Focusing on a landscape-level understanding of terrestrial, aquatic & marine species & ecosystems, through data integration and visualization.
SAS biodiversity science activities focus on the landscape-level understanding of terrestrial, aquatic, and marine species and ecosystems, through development, maintenance, and integration of a suite of synthesized data systems used to conduct biodiversity assessments at regional to national scales.
The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.
Biodiversity Information Serving Our Nation (BISON) is a web-based resource for species occurrence data in the U.S. and its Territories. BISON holds over 380 million species occurrence records, encompassing most living species found in the United States, from a broad array of sources, including museums, monitoring programs, research studies, citizen science and peer-reviewed literature.
The Dam Removal Information Portal (DRIP) is a web application where partners, scientists, and practitioners can find information on dam removals and associated scientific studies. It is a visualization tool, including a map and interactive charts, of a dam-removal literature review designed and developed by a working group at the USGS John...
GAP provides data to assess effects of land management by providing information on where species and natural communities occur and how they are being managed. "Gap analysis" assesses how well we are protecting common plants and animals by identifying the degree to which animal species and plant communities are under-represented on protected lands such as parks and refuges.
The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program. The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.
Generate a hydrologic linear reference for point data representing locations of geographic features or field samples using the HydroLink Tool. This web-based GIS application allows for upload of a csv file or shapefile for easy linkage of spatial data records to the National Hydrography Dataset (NHD) Plus Medium Resolution and NHD High Resolution hydrology layers.
With more than 700,000 scientifically vetted entries, the ITIS is the authoritative source for scientific names of species and higher-level groups of organisms in North America and the world. It is produced in conjunction with eight other Federal partners. Its partnership with the European-based Species 2000 yields the global names standard: Catalogue of Life.
The National Vegetation Classification (NVC) is your guide to inventorying plant communities. The standard allows users to produce uniform statistics about vegetation resources across the nation. CSAS&L actively participates in the development of this important standard through our involvement with the FGDC Vegetation Subcommittee and the ESA Vegetation Panel.
OBIS-USA is the US Node of the Ocean Biogeographic Information System, providing the collection and distribution point to OBIS of marine biogeographic records in U.S. waters or collected with U.S. funding. Using the Darwin Core standard, OBIS-USA integrates and makes accessible data on marine species presence, absence, and abundance to aid scientists, resource managers, and decisions makers....
The Protected Areas Database of the United States (PAD-US) Viewer provides a spatially explicit inventory that lets any user explore the protected areas network anywhere in the United States and allows them to easily use this inventory in conservation, land management, planning, recreation and other uses.
Species of Greatest Conservation Need are lists of species designated in the 56 State Wildlife Action Plans which identify the species most in need of conservation action in that state or U.S. territory. USGS developed a process that allows these lists to be compiled into a national list, making their representation across taxa groups available via the Species Conservation Analysis Tool.
This report summarizes the results of an unprecedented nationwide assessment of human effects on fish habitat in the rivers and estuaries of the United States. The assessment assigns a risk of current habitat degradation scores for watersheds and estuaries across the nation and within 14 sub-regions. The results also identify some of the major sources of habitat degradation.
