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.
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 ...
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil .
Wet meadows were once common in wetland types around the world. [4] [5] They remain an important community type in wet savannas and flatwoods. [6] The also survive along rivers and lakeshores where water levels are allowed to change within and among years. [7] But their area has been dramatically reduced.
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.
Monitoring of wildlife populations is an important part of conservation because it allows managers to gather information about the status of threatened species and to measure the effectiveness of management strategies. Monitoring can be local, regional, or range-wide, and can include one or many distinct populations.
