Ecosystems whose soil is saturated for long periods seasonally or continuously, including marshes, swamps, and ephemeral ponds. More detailed terms for wetlands can be selected from the FGDC Wetland Classification <http://fgdc.gov/standards/status/sub3_4.html>.
Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.
Detailed publication on the classification system for an inventory of wetlands and deepwater habitats of the United States used to describe ecological taxa and arrange them in a system useful to resource managers.
Comprehensive bibliography on the ecology, conservation, and management of North American waterfowl and their wetland habitats. Facilitates searching or downloading as *.zip files and use with ProCite utility.
Study of the effects of the practice of cycling municipal nutrient-enriched wastewater from holding ponds through forested wetlands. Studies were in the Cypiere Perdue Swamp, Louisiana, and the Drummond Bog, Wisconsin.
Overview with links to studies on the effects of human activity on the San Francisco estuary with loss of historic fresh and saltwater tidal marshes reducing habitats, introducing contaminants in waste, and creating dredging problems.
Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services. Changes in climate and land use can affect the value of those services. We study these areas to understand how they may be changing.
Will salt marshes survive if sea level rises quickly? The answer depends on whether the areas surrounding them can allow salt marsh fauna and flora to migrate there. Local topography, both natural and manmade, is the main factor limiting this migration.
Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
The U.S. Geological Survey uses remote sensing to improve fire-management databases in the Everglades, gain insights into post-fire land-cover dynamics, and develop spatial and temporal fire-scar data for habitat and hydrologic modeling.
Main page for accessing links for information and data on the San Francisco Bay estuary and its watershed with links to highlights, water, biology, wetlands, hazards, digital maps, geologic mapping, winds, bathymetry and overview of the Bay.
Integrated network of real-time water-level monitoring, ground-elevation modeling, and water-surface modeling that provides scientists and managers with current on-line water-depth information for the entire freshwater portion of the Greater Everglades.
Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.
Explains how we assessed the quality of a wetland as indicated by its plant species composition and abundance for marsh and swamp sites, to summarize the effectiveness of restoration projects in Louisiana.
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.
Portal of the South Florida Information Access (SOFIA) system providing multiple links to projects, products, information, and data for research, decision-making, and resource management of the South Florida ecosystem restoration effort.
A pictorial overview for general audiences of key landscapes and ecosystems in South Florida; includes extensive references and links to past and current research activities relating to the South Florida ecosystem restoration effort.
This report serves as an environmental review and framework for developing USGS programs in the south Florida ecosystem, especially the Everglades and its watershed, and stresses the critical role of water in natural and human environment.
Information on objectives, approach, status, and publications of various research projects investigating water resources in Montana including studies on wetlands, bridge scour, reconstructed wetlands, abandoned mine lands, and others.
