Document Summary
Wet at some point during the year. Hydric soils (formed by water processes that are different from upland habitat: hydric soils are anoxic (do not have oxygen available to plants or invertebrates) when they are wet , anoxic b/c soil is thin. Support hydrophytic vegetation (vegetation that can or may be in wetland conditions) Wetland indicator species : wetland types, distinguished by water flow and vegetation, surface water wetland. Receive water from precipitation and surface flows. Include surface water slope and surface water depression wetlands: ground water wetland. Get water from underground sources like the water table or subsurface aquifer. Ground water depression wetland (water flows in from underground water table: bogs, fens, marshes. Open system (water flows in and out) Slow by steady flow of water: swamps. Riparian forest in sacramento valley is best documented losses with 1. 5% riparian forest surviving. Greatest cause - loss of 87% of wetlands: urban development.
