A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season".

Children celebrating World Wetlands Day. World Wetlands Day is an environmentally related celebration which dates back to the year 1971 when several environmentalists gathered to reaffirm protection and love for wetlands, [1] which are water ecosystems containing plant life and other organisms that bring ecological health in abundance to not only water bodies but environments as a whole.
They have conserved more than 12,000,000 acres (49,000 km 2) of wetlands in North America and influenced another 47,000,000 acres (190,000 km 2). [6] The Nature Conservancy, Audubon Society, and Pheasants Forever are a few more of the large private groups that focus part of their time and resources on wetlands conservation. Individuals should ...
Coastal wetlands also reduce pollution from human waste, [41] [42] remove excess nutrients from the water column, [43] trap pollutants, [44] and sequester carbon. [45] Further, near-shore wetlands act as both essential nursery habitats and feeding grounds for game fish, supporting a diverse group of economically important species. [46] [47] [48 ...
The convention establishes that "wetlands should be selected for the list on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology." Over the years, the Conference of the Contracting Parties has adopted more specific criteria interpreting the convention text.
A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. [1] Wet prairies and wet savannas are hydrologically similar.
On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas, they harbor salt marshes , mangroves or seagrasses , all of which can provide nursery habitat for fin fish , shellfish , and other aquatic animals .
