Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. [1] Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.
Wetlands help maintain the level of the water table and exert control on the hydraulic head. [5] [6] This provides force for groundwater recharge and discharge to other waters as well. The extent of groundwater recharge by a wetland is dependent upon soil, vegetation, site, perimeter to volume ratio, and water table gradient.
Floodplains and closed-depression wetlands can provide the functions of storage reservoirs and flood protection. The wetland system of floodplains is formed from major rivers downstream from their headwaters. "The floodplains of major rivers act as natural storage reservoirs, enabling excess water to spread out over a wide area, which reduces ...
The Wetland Reserve Program (WRP) funds landowners that volunteer their land for wetland development and provides opportunities for landowners participate in the maintenance of the project. The land must meet specific requirement to receive funding and the program is set up for each state in the United States.
Shelterwood cutting allows for timber extraction, while maintaining ecosystem structure and allowing forest regeneration. The term natural resource management is frequently used in relation to a particular resource for human use, rather than the management of a whole ecosystem. [34]
The EPA and Army Corps of Engineers announced a new definition of “waters of the United States” intended broaden protections for wetlands, rivers and tributaries. EPA issues new rule to ...
There are a number of government agencies in the United States that are in some way concerned with the protection of wetlands. The top five are the Army Corps of Engineers (ACoE), Natural Resources Conservation Service (NRCS), Fish and Wildlife Service (FWS), National Oceanic and Atmospheric Administration (NOAA), and the Environmental Protection Agency (EPA).

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 .
