Some Gyan about Wetland.
Type of Wetland:
The term ‘Wetlands’ is broadly used to refer to swamps, marshes, bogs, prairie potholes, flood plains, and fen. These are lands which due to geological or ecological factors, have a natural supply of water—either from tidal flows, flooding rivers, connections with groundwater, or because they lie above aquifers or potholes.
Marshes: A freshwater marsh is an inland area inundated with anywhere between 1- 6 feet of water, containing a variety of grasses, flowers and bushes, rather than trees, unlike as in swamps.
They have an interesting mix of plant and animal life and are home to yellow-headed and red-winged blackbirds, herons, egrets, rails, bitterns, moorhens, ducks and geese.
Marshes also host frogs, turtles, snakes, salamanders, a diverse variety of insects, including aquatic, flying, and grazing insects.
Marshes that occur along rivers are called riparian marshes. These marshes serve two ecological roles: to absorb excess water when river levels are high and to release water when the river levels are low. These balancing forces help prevent floods and droughts.

Swamps: Swamps are slow moving streams, rivers or isolated depressions that host trees and some shrubs. A bog is a peat-accumulating wetland. Some shrubs and evergreens grow in bogs, as does moss. Most water comes from precipitation. There is usually no direct inflow or outflow of water.

Prairie potholes: Prairie potholes are shallow or bowl-like depressions have variable wetness. They are often used as breeding grounds by birds. They are not wet year-round.
