Closer Look

Wetlands are areas such as swamps, bogs, and marshes where water either covers the soil or is present at or near the surface, particularly in the root zone, at least a good portion of the year, including the growing season. In the past, wetlands were generally considered unproductive or undesirable lands—smelly and unhealthful, a breeding ground for mosquitoes and other pests—and many were filled in to create farmland or to develop land for housing and industrial use. More than half of the original wetlands in the continental United States have disappeared in the name of reclamation, disease prevention, and flood control. Scientists now realize that, far from being noxious barrens, wetlands play a key role in the ecosystem. They act as filters, removing pollutants, including metals, from waters. They serve as reservoirs, and they aid flood and erosion control by absorbing excess water. Wetlands are home to a great variety of plant and animal species, some endangered, that have evolved to live in the wetland's unique conditions. The preservation and, where possible, restoration of these vital habitats has become a primary goal of environmentalists around the world.

Etymology

Origin of wetland

First recorded in 1770–80; wet + -land

Explanation

An ecosystem that is extremely soggy — like a bog or a swamp — is a wetland. You can find plants including cattails and water lilies growing in wetlands. Coined in the 1740s, wetland is a fairly obvious combination of wet and land, which perfectly describes what they're like. Whether they're saturated with saltwater or freshwater, these ecosystems support many species of animals and plants. The presence of organisms that have adapted to live in areas that are usually (but not always) flooded is what distinguishes marshes, estuaries, and other wetlands from bodies of water.
