22.2 - Temporary freshwater bodies

Classification des habitats du Paléarctique (2001)

Description

Freshwater lakes, ponds, pools, or parts of such freshwater bodies, which become periodically dry, with their associated animal, green algal or lower algal pelagic (units 22.21 - 22.25) and benthic (units 22.26, 22.27) communities. The macrophytic-based amphibious communities that may colonize them are separately listed under unit 22.3, terrestrial communities that may develop during their dry phase under unit 22.5, drawdown resistant euhydrophyte communities under unit 22.2, fringing belts or island rafts of rooted or floating tall emergent vegetation under unit 53. Permanently or almost permanently emerged features supporting terrestrial communities influenced by the presence of the water body are included in unit 22.6. Grasslands, shrublands and woodlands which may at times be inundated but in which semicontinuous formations of grasses, shrubs or trees emerge at all times above the standing water surface are listed under units 37, 3A, 44 and 4A, not under unit 22.2.
