Facultative upland (FACU) - Usually occurs in non-wetlands (estimated probability 67% – 99%), but occasionally found in wetlands (estimated probability 1% – 33%). Obligate upland (UPL) - Almost always occurs in non-wetlands under natural conditions (estimated probability > 99%).
Facultative (FAC), facultative wetland (FACW), or facultative upland (FACU): wetland indicator statuses for plants; Facultative anaerobe, an organism that can use oxygen but also has anaerobic methods of energy production. It can survive in either environment
Facultative lagoon (polishing pond) providing tertiary treatment after a constructed wetland in Hamburg-Allermöhe, Germany. Overflow from the facultative lagoon may be routed through one or more polishing ponds supporting lower populations of anaerobic micro-organisms and a higher proportion of aerobic organisms adapted to survival in lower concentrations of organic material.
Rosa pisocarpa has a wetland indicator status of FAC for the Pacific Northwest (region 9) and FACU for California (region 0). [3] It grows in full sun in the northern and wetter portions of its range, but also tolerates partial shade, and can grow in dry or lean soils.
The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
The plant is categorized Wetland Indicator Status: FACU (Facultative Upland). [6] The flowers are small and white, bourne in mid-late summer. [7] The seeds are burs, and are very sticky. The plant is native but a well-known nuisance in deciduous forests of the eastern U.S. because the seeds can be difficult to remove from clothing and ...
Constructed wetlands are designed to improve water quality by supporting rooted vegetation arranged to physically remove solids and particulate material while removing soluble nutrients in the water by uptake into plant tissue and supplying oxygen to the water to reduce BOD.
Wetlands are frequently being destroyed for development, agriculture, and other uses. Wetlands have decreased by as much as 50% since 1900 and in some parts of the world by 90%. [ 19 ] [ 20 ] Inland wetlands, freshwater marshes making up about 20-25% of all freshwater wetlands globally, [ 21 ] have been decreasing approximately 1.2% each year ...
