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>.
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.
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.
