Why are wetlands important?
Wetlands provide habitat for thousands of species of aquatic and terrestrial plants and animals. Wetlands are valuable for flood protection, water quality improvement, shoreline erosion control, natural products, recreation, and aesthetics.
Wetlands are among the most productive habitats on earth providing shelter and nursery areas for commercially and recreationally important animals like fish and shellfish, as well as wintering grounds for migrating birds. Coastal marshes are particularly valuable for preventing loss of life and property by moderating extreme floods and buffering the land from storms; they also form natural reservoirs and help maintain desirable water quality.

What is the Brown Marsh phenomenon?
Sudden marsh dieback events are not uncommon and have occurred in coastal marshes from the Gulf of Mexico to Maine. Brown Marsh is a term given to the unusually rapid and extensive browning of Louisiana’s saltwater marsh grass Spartina alterniflora, commonly known as oyster grass or smooth cordgrass. One of the most severe events occurred in 2000, when over 100,000 hectares (ha) of salt marsh were...
What are wetlands?
Wetlands are transitional areas, sandwiched between permanently flooded deepwater environments and well-drained uplands, where the water table is usually at or near the surface or the land is covered by shallow water. They include mangroves, marshes (salt, brackish, intermediate, and fresh), swamps, forested wetlands, bogs, wet prairies, prairie potholes, and vernal pools. In general terms...

Mercury and Rice in the California Delta: Lessons Linking Wetlands to Water to Wildlife
- Wetlands are hotspots for mercury methylation and export of methylmercury to aquatic foodwebs.
- Rice is the most abundant wetland type in California and globally in temperate and tropical latitudes.

Effects of Sea-Level Rise on Coastal Wetlands in the Mississippi Delta
This video describes research being conducted by Dr. Karen McKee, USGS Research Ecologist, and her university partner, Dr. Julia Cherry. Their goal is to better understand the effects of sea-level rise and other global change factors on coastal wetlands in the Mississippi River Delta. This region contains over 40% of the U.S.

Wetland Revival
USGS scientists deliver a variety of science in the effort to restore wetlands to over 25,000 acres in San Francisco Bay. "Wetland Revival" shows how science is contributing to the transformation of once industrial salt producing ponds into more natural habitat. The program was completed in 2008. USGS General Information Product 61.
