A new 30-m spatial resolution global shoreline vector (GSV) was developed from annual composites of 2014 Landsat satellite imagery. The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, and the resulting polygons were mapped into four size classes of islands: Continental Mainlands, Big Islands (greater than 1 km2), Small Islands (less than or equal to 1 km2 and greater than or equal to 0.0036 km2), and Very Small Islands (less than 0.0036 km2).

Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.

As the impacts of climate change amplify, understanding the consequences for wetland dynamics will be critical for their sustainable management and conservation, particularly in arid regions such as the CP ecoregion. However, the data to model climate impacts to wetland ecosystems has been hampered by the lack of accurate maps showing their spatial distribution and data on their historical hydrological dynamics. Though these data may exist for particular wetlands, there are no wall-to-wall consistent datasets of wetland location and long-term hydrological dynamics. Climate change has emphasized the growing need to plan conservation actions across large landscapes and at a longer-term time scales. As such, consistent...

The Southern Rockies LCC is home to narrowleaf cottonwood (Populus angustifolia), common at elevations above 1800 m, and Fremont cottonwood [a common name regionally attached to the ecologically very similar Populus fremontii subsp. fremontii S. Watson and P. deltoides subsp. wislizenii (S. Watson) Eckenwalder, as well as their intergrades], which is typically found at elevations below 1800 m. This geographical information system (GIS) contains the data sets used in an assessment of the amount and character of native Fremont cottonwood forest remaining on the mainstem floodplains in 26 subbasins in the Upper Colorado River Basin (UCRB), published in 2007 (Andersen, D.C., D.J. Cooper, and K. Northcott. 2007. Dams,...

Landscape Conservation Cooperatives (LCCs) are public-private partnerships composed of states, tribes, federal agencies, non-governmental organizations, universities, international jurisdictions, and others working together to address landscape and seascape scale conservation issues. LCCs inform resource management decisions to address broad-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are magnified by a rapidly changing climate. For further information go to https://www.fws.gov/science/catalog. The previous 2011 LCC Network Areas data is available at https://www.sciencebase.gov/catalog/item/52f2735ee4b0a6f0bd498c2f

This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series SIM-3143 (Sherrod and others, 2021). This geologic map shows the distribution and stratigraphic relation of volcanic, intrusive, and sedimentary units emplaced in the past 8 million years across the eight principal islands of the Hawaiian archipelago, State of Hawaii, U.S.A. This geologic map database is accompanied by a report, which includes the formatted geologic map and explanatory pamphlet, available at https://doi.org/10.3133/sim3143​. The authors ask that users of the geologic map database cite both the report and the database: Report: Sherrod, D.R., Sinton, J.M.,...
