Wetlands function as natural sponges, that traps and slowly releases surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats, and other wetland vegetation are also slowing the speed of flood waters and distribute them more slowly over the floodplains. This combined water storage and braking actions, lowers the flood heights and reduces erosion.
More than one third of the US threatened species live in wetlands.
Wetlands are some of the most biologically productive natural ecosystems in the world.
Wetlands have important filtering capabilities.
Water storage is one of the important abilities of wetlands.
The ability of wetlands to control erosion is very valuable.
We use a wealth of natural products from wetlands and use them for recreation.
Global warming and lack of knowledge are reasons why wetlands are threatened ecosystems.
