Eventually, peat builds up to a level where the land surface is too flat for ground or surface water to reach the center of the wetland. This part, therefore, becomes wholly rain-fed (ombrotrophic), and the resulting acidic conditions allow the development of bog (even if the substrate is non-acidic).
Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat ...
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]
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.
Permanent freshwater ponds (< 8 ha), marshes and swamps on inorganic soils; with emergent vegetation waterlogged for at least most of the growing season Seasonal/intermittent freshwater ponds and marshes on inorganic soils; includes sloughs , potholes; seasonally flooded meadows, sedge marshes
Indonesia has the largest area of tropical peatland. Of the total 440,000 km 2 (170,000 sq mi) tropical peat swamp, about 210,000 km 2 (81,000 sq mi) are located in Indonesia (Page, 2001; Wahyunto, 2006). The Vasyugan Swamp is a large swamp in the western Siberia area of the Russian Federation.

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 ...
