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.
