Wetland conservation is aimed at protecting and preserving areas where water exists at or near the Earth's surface, such as swamps, marshes and bogs. Wetlands cover at least six per cent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.
In the European Union (EU), since 2000, the Water Framework Directive (WFD) aims to achieve a number of objectives to improve water quality of lakes, rivers and coastal areas. [23] Key objectives are general protection of the aquatic ecosystem, protection of drinking water resources, and protection of swimmable waters. [ 23 ]
[19] [20] Inland wetlands, freshwater marshes making up about 20-25% of all freshwater wetlands globally, [21] have been decreasing approximately 1.2% each year throughout the last century (since 1900). [22] [23] Wetland restoration, or bringing back the wetland and its functions, [24] is an
A wetland (aerial view) 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.
A pond that was dug deep enough to reach the water table provides a continuous supply of water to the adjacent swale. To the west of the building is a small decorative wetland and an emerging red maple swamp. In June 2008, the Olentangy River Wetland Research Park was formally designated as the USA's 24th Ramsar Wetland of International ...
The unique biodiversity of riparian ecosystems and the potential benefits that natural, vegetated riparian have to offer in preventing erosion, maintaining water quality that ranges from being decent to completely healthy, providing habitat and wildlife corridors, and maintaining the health of in-stream biota (aquatic organisms) has led to a ...
The Wetlands Initiative works with nonprofit and government partners and local communities to advance wetland restoration and science in the Midwestern United States. [4] The organizational vision of TWI is: "A world with plentiful healthy wetlands improving water quality, climate, biodiversity, and human well-being." [1]
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.
