| riparian wetland | <ecology> Riparian vegetation composed primarily of woody hydrophytes (for example, such as willows, alders, cottonwoods, sycamores, box elders, aspens, etc.). (09 Oct 1997) |

| riparian | Relating to a ripa; marginal. (05 Mar 2000) |
|---|---|
| riparian area | An area of land directly influenced by water. An ecosystem that is transitional between land and water ecosystems. Riparian areas usually have visible vegetative or physical characteristics reflecting the influence of water. River sides, lake borders, and marshes are typical riparian areas. (05 Dec 1998) |
| riparian buffer | Riparian areas that are managed to protect the aquatic and riparian ecosystem. A riparian buffer protects water quality and temperature, habitat along the banks, upland habitat for aquatic and riparian species, and some or all of the floodplain. (05 Dec 1998) |
| artificial wetland | <ecology> Wetlands created by the activities of man, either purposefully or accidentally. (09 Oct 1997) |
| manmade wetland | <ecology> Any wetland area that has been purposely or accidentally created by some activity of humans. (09 Oct 1997) |
| perched wetland | <ecology> Wetlands away from stream or river influence with water made available by general drainage. (09 Oct 1997) |
| wetland hydrology | <ecology> In general terms, permanent or periodic inundation or prolonged soil saturation sufficient to create anaerobic conditions in the soil. (09 Oct 1997) |
| wetland indicator status | <ecology> The exclusiveness with which a plant species occurs in wetland, the different indicator categories (i.e., facultative species, and obligate wetland species) are defined elsewhere in this glossary. (09 Oct 1997) |
| moss-lichen wetland | <ecology> A wetland dominated by mosses (mainly peat mosses) and lichens with little taller vegetation. (09 Oct 1997) |
| comprehensive wetland determination | <ecology> A type of wetland determination that is based on the strongest possible evidence, requiring the collection of quantitative data for all three wetland identification criteria. (05 Jan 1998) |
| problem area wetland | <ecology> A wetland that is difficult to identify because it may lack indicators of wetland hydrology and/or hydric soils, or its dominant plant species are more common of nonwetlands. (09 Oct 1997) |
| historic wetland | <ecology> An area of land that is no longer a wetland but which once was, usually refers to areas that were wetlands at the beginning of the Gold Rush (1849). (09 Oct 1997) |
| degraded wetland | <ecology> A wetland which has been altered by man through impairment of some physical property and in which the alteration has resulted in a reduction of biological complexity in terms of species diversity of wetland-associated species which previously existed in the wetland areas.
