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.
Wetland conservation. 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.
An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". [ 1 ] Sometimes a precise legal definition of a wetland is required.

Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and ...
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.
The Baker Wetlands (also known as the Haskell-Baker Wetlands) is a nature preserve and artificially sustained wetland, [ 1] spanning approximately 927 acres (3.8 km 2) [ 2] south of Lawrence, Kansas, United States. It is associated with the Wakarusa River and sustained by levees and flood controls built in the 1990s. [ 3]
