Website for the Columbia Environmental Research Center with links to staff, publications, databases, field stations, and projects including those on the Rio Grande, burrowing owls, sea turtles, and geospatial technology.
Overview of research of the Ecology Branch on the ecological consequences of habitat degradation due to altered environment, nonindigenous species, and atmospheric alterations. Includes links to staff and research projects.
Study of wildland fire history and fire ecology such as plants in the Sierra Nevada forests, California shrublands, the Mojave, and Sonoran deserts to develop management techniques that will reduce hazards.
Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
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.
Site for the Platte River Program in Nebraska an area that is a critical staging area for migratory waterbirds of the Central Flyway. Includes links to color-infrared aerial photos, 1938 historic aerial photos, and Cottonwood Ranch research site.
The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. The USGS has modeled the future responses of polar bear and Pacific walrus populations to this environmental change.
Report on the Sirenia Project use of a radio tracking study to determine manatee movement patterns and habitat to develop ecological models to understand and predict the effects of hydrologic restoration on manatees in Southwest Florida.
Explains 16 distinct types of scientific information that are needed to understand climate change, including the specific parameters measured, why they are needed, who measures them, and the type and amount of information that are not yet available.
Thematic descriptions of research to meet the varied needs of the fire management community and to understand the role of fire in the landscape including fire management support, studies of postfire effects, and fire history and ecology.
