An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem.

While the issue lingers on in municipal planning meetings around the country, the federal government does what it can to protect wetlands. They provide habitat for animals and plants and many contain a wide diversity of life, supporting plants and animals that are found nowhere else. The functions of a wetland and the values of these functions to humans depend on a complex set of relationships between the wetland and the other ecosystems in the watershed. “Wetlands are vulnerable to over-exploitation due to their abundance of fish, fuel and water,” reports the group, which works on the ground in 18 countries to educate the public and policymakers about the health of local wetlands and to advocate for better policies. The widespread expansion of development in the U.S. in recent decades has brought the issue of wetlands loss to the forefront of debates on zoning and land use planning. found in wetlands. Consequently, human interference with these disturbance regimes can irreversibly alter a wetland. How does Overpopulation Impact on Our environment? Wetland - Wetland - Wetland functions and ecosystem benefits: Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Wetlands store our water to ensure supply during dry periods. The holding capacity of wetlands helps control floods and prevents water logging of crops. Based on early bog studies, the classic view of lake succession was that a shallow lake would fill in over time and become a wetland.

Ross and Leonard David | Opinion. Wetlands can also be key drivers of local economies, given their importance to agriculture, recreation and fishing. Endangered Species List live only in wetlands and almost half use them at some time during their lifecycles. Wetlands are valuable for flood protection, water quality improvement, shoreline erosion control, natural products, recreation, and aesthetics. Climate, landscape shape (topology), geology and the movement and abundance of water help to determine the plants and animals that inhabit each wetland.
They are among the world’s most productive environments; cradles of biological diversity that provide the water and productivity upon which countless species of plants and animals depend for survival.
Wetlands can be thought of as "biological supermarkets." Free Trial Issue: www.emagazine.com/trial. © 2020 Scientific American, a Division of Springer Nature America, Inc.

Beavers alter wooded landscapes by cutting trees for dam material and by impounding stream water.

Many wetland plant communities, however, are adapted to stressful conditions and have developed in concert with natural disturbances that “reset” succession or override short-term changes. Wetlands are the vital link between land and water. A warming climate will have hard-to-predict effects in northern latitudes, where seasonal melting of frozen ground controls the existence of wetlands in the landscape. This certainly beats expensive, human-made filtration systems. Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs.
