Organism groupings (non-taxonomic)
Used for categories of living organisms that are not taxonomic and that include species from more than one taxonomic group.
Invasive species program [ More info] This program provides management-oriented research and delivers information needed to prevent, detect, control, and eradicate invasive species, and to restore impaired ecosystems.
Invasive Species Program -- Snakeheads, aquatic invaders [ More info] Snakeheads, aggressive airbreathing freshwater fishes that are not native to North America, are considered injurious to certain native North American fish and other aquatic wildlife.
Invasive species research [ More info] Links to research projects that will improve the ability to detect, monitor, and predict the effects of invasive species, including exotic animals, on native ecosystems of the Pacific Southwest (California, Nevada, Utah, and Arizona).
Is science in danger of sanctifying the wolf? [ More info] What does it mean that beneficial trophic cascades (side effects) of wolf population restoration are questioned by recent research?
LANDFIRE [ More info] A collection of geospatial data sets intended to support wildfire response and other natural resource planning activities. Includes vegetation, fire regimes, topography, surface disturbance, fuel models, and reference data.

Macroinvertebrate and algal community sample collection methods and data collected at selected sites in the Eagle River watershed, Colorado, 2000-07 [ More info] Macroinvertebrate data collected by USGS or USFS from 73 sites from 2000 to 2007 and algal data collected from up to 26 sites between 2000 and 2001 in the Eagle River watershed, with emphasis on methods of sample collection and data processing.
Mapping perennial vegetation cover in the Mojave Desert [ More info] Field data and satellite images allow us to make a calibrated model of percent vegetation cover, which we can use to inform scientific investigations and land management efforts.
Maps of distribution and abundance of selected species of birds on uncultivated native upland grasslands and shrubsteppe in the northern Great Plains [ More info] Links to maps of breeding distributions of bird species on grasslands and shrublands in the northern Great Plains.
