[2] [3] They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. [4] [5] Bogs occur where the water at the ground surface is acidic and low in nutrients. A bog usually is found at a freshwater soft spongy ground that is made up ...
This site is described by Natural England as "one of the finest remaining areas of wet unimproved grassland in Norfolk". It is traditionally managed by summer grazing, with plants such as glaucous sedge and bog pimpernel in marshy parts and blunt-flowered rush and carnation sedge in permanently wet areas. [40] Bilsey Hill: 3.0 hectares (7.4 ...
The water from rain and snow collects, forming permanently waterlogged vegetation and stagnant pools. Muskeg is wet, acidic, and relatively infertile, which prevents large trees from growing, although stunted shore pine, cottonwood, some species of willow, and black spruce are typically found in these habitats.

A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". [15]
Amazonian white water river floodplains cover an area of more than 300,000 km 2, and várzea forests cover approximately 180,000 km 2 of the Amazon basin. 68% of the Amazonian river basin is located in Brazil, with the remaining areas located in Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Guyana. The várzea extends from this ...
In 2008, data covering 66,200,000 acres (268,000 km 2) were added to the Wetlands Geodatabase. These included 28,100,000 acres (114,000 km 2) of updated wetland map information, new data for 6,800,000 acres (28,000 km 2) not previously available and 31,300,000 acres (127,000 km 2) of data that were captured in digital format. An additional ...
It is permanently waterlogged, with a gradient of saline to fresh water arising from regular tidal inundation at the seaward fringe and freshwater flooding from inland. During the dry season, parts of the reserve may become hypersaline. The site's elevation is generally sea level, but rises to approximately 4 ft (1.2 m) along river banks. It ...
The sheeting of water keeps the edges of the rock wet without eroding the soil, but in this precarious location no tree or large shrub can maintain a roothold. The result is a narrow, permanently wet, sunny habitat. While a cataract bog is host to plants typical of a bog, it is technically a fen, not a bog. Bogs get water from the atmosphere ...
