Bog
A peat-accumulating wetland that has no significant inflows or outflows and supports acid-loving mosses, particularly sphagnum. Water comes mostly from precipitation. Some shrubs and evergreens also grow in bogs.

Bottomlands
Lowlands along streams and rivers, usually in the floodplain (land adjacent to the banks that becomes flooded when water overflows normal levels). Often forested, and sometimes called riparian wetlands or bottomland hardwood forests.

Delmarva or Carolina bay ("whale wallow")
An isolated, irregularly shaped or elliptical basin fed by rain or ground water, containing dark-colored acidic water. These basins may support trees or shrubs, and may dry up in late summer. They are found in coastal regions of the eastern United States, and their origin is uncertain.

Fen
A peat-accumulating wetland that receives some drainage from surrounding mineral soil usually supports marsh-like plants.

Mangrove
A tropical saltwater marsh vegetated mostly by herbaceous plants that grow up out of the water (emergents) and is frequently or continually flooded. "Mangrove" refers to the type of trees that inhabit thse muddy tropical shores.

Marsh
A fresh, brackish, or saltwater wetland, vegetated mostly by herbaceous plants that grow up out of the water (emergents). Marshes are frequently or continually flooded, and are often found on the edges of rivers, creeks, ponds, and lakes, in isolated depressions, and along coasts.

Mire
Any peat-accumulating wetland (commonly used term in northern Europe).

Moor
A high moor is a raised bog, and a low moor is in a basin or depression (European).

Muskeg
A large expanse of peatlands or bogs, particularly common in Canada, Alaska, and Siberia.

Peatland
Any wetland that accumulates partially decayed plant matter, or peat.

Playa lake
Temporary ponds formed in desert landscapes; characterized by internal drainage systems (common in the western United States). Vegetation is usually marshlike.

Potholes
Shallow marshlike ponds in the Midwestern United States and the prairie provinces of Canada.

Slough
A swamp or Shallow lake in the northern and Midwestern United States, of a slowly flowing, shallow swamp/marsh in the southeastern United States.

Swamp
A wetland vegetated mostly by trees and shrubs; often associated with rivers, slow streams, or isolated depressions.

Wet meadow
A grassland with waterlogged soil near the surface but without standing water for most of the year.
