The Pantanal is a natural region encompassing the world's largest tropical wetland area. It is located mostly within the Brazilian state of Mato Grosso do Sul, but it extends into Mato Grosso and portions of Bolivia and Paraguay. It sprawls over an area estimated at between 140,000 and 195,000 square kilometres (54,000 and 75,000 sq mi).
This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included.
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]
Bayou – Body of water in flat, low-lying areas; Bog – Type of wetland with peat-rich soil; Coniferous swamp – Forested wetlands dominated by conifers; Fen – Type of wetland fed by mineral-rich ground or surface water; Freshwater swamp forest – Forest growing on an alluvial zone; Hydrogen sulfide – Poisonous, corrosive and flammable gas
Freshwater swamp forests contain soft, unstable, and anoxic soil due to their waterlogged condition, which may have influenced the evolution of unique root adaptations in these trees that resemble those seen in a real mangrove forest. [17] [18]
The Low Elevation Coastal Zone (LECZ) refers to low-lying coastal areas with an elevation below a certain threshold, commonly 10 meters, above mean sea level.Globally, there is a substantial and growing population living in the Low Elevation Coastal Zone, which consists of approximately 2% of the world's land area and around 11% of the global population.
New Guinea is home to extensive swamp forests. These forests are permanently waterlogged or seasonally inundated during the rainy season. The Southern New Guinea freshwater swamp forests extend from the western Bird's Head Peninsula to the Papuan Peninsula in the southeast. The forests lie in the lower reaches of the rivers that drain New ...
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).
