An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". [1] Sometimes a precise legal definition of a wetland is required.
A fen is a type of peat -accumulating wetland fed by mineral-rich ground or surface water. [1][2] It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. [2] The unique water chemistry of fens is a result of the ground or surface water input.
Marshlands are often noted within wetlands, as seen here in the New Jersey Meadowlands at Lyndhurst, New Jersey, U.S. Marsh in shallow water on a lakeshore. In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants. [1] More in general, the word can be used for any low-lying and seasonally waterlogged ...
The Ramsar classification of wetland types is intended as a means for fast identification of the main types of wetlands for the purposes of the convention. [2] The wetlands are classified into three major classes: Marine/coastal wetlands. Inland wetlands. Human-made wetlands.
Wetland conservation. 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 duduk or mey mouthpiece is a flattened piece of giant reed Arundo donax a relative of common reed, which itself is flattened to make the zurna reed. In Middle East countries Phragmites is used to create a small instrument similar to the clarinet called a sipsi, with either a single, as in the picture, or double pipes as in bagpipes. [8]
Lepironia articulata, the gray sedge. Lycopus lucidus. Lysimachia maritima. Nechamandra alternifolia. Nelumbo nucifera, the sacred lotus. Nymphaea nouchali, the blue water lily. Oryza coarctata, syn. Porteresia coarctata, a type of wild rice that grows in estuaries [2] Persicaria hydropiper. Persicaria thunbergii.
Major remaining wetlands of the United States. Red dots indicate critical wetlands. The U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI) produces and provides information on the characteristics, extent, and status of U.S. wetlands and deepwater habitats and other wildlife habitats.
