The ORMLT is a non-profit organization that raises funds to protect areas on the moraine through conservation easements and outright purchases. They have protected 6 square kilometres (1,500 ...
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.
The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) is a 1990 United States federal law that provides funds for wetland enhancement. [1] The law is implemented by federal and state agencies, focusing on restoration of lost wetlands of the Gulf Coast , as well as protecting the wetlands from future deterioration.
The Cowardin classification system is a system for classifying wetlands, devised by Lewis M. Cowardin et al. in 1979 for the United States Fish and Wildlife Service. The system includes five main types of wetlands: Marine wetlands- which are areas exposed to the open ocean
Wetlands can be part of the lentic system, as they form naturally along most lake shores, the width of the wetland and littoral zone being dependent upon the slope of the shoreline and the amount of natural change in water levels, within and among years. Often dead trees accumulate in this zone, either from windfalls on the shore or logs ...
Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
The wetland status of 7,000 plants is determined upon information contained in a list compiled in the National Wetland Inventory undertaken by the U.S. Fish and Wildlife Service and developed in cooperation with a federal inter-agency review panel (Reed, 1988). The National List was compiled in 1988 with subsequent revisions in 1996 and 1998.
Areas of land that are wet by surface water or groundwater for long periods of time so that the animals and plants adapt to them for a part of their lifecycle are considered Wetlands. This includes areas that are inundated with fresh or saline water. Lagoons, lakes, rivers, estuaries, swamps, coral reefs and seagrass beds are examples of ...
