Robert Lichvar. A wetland is an ecosystem within itself, which is defined by the presence of water flowing and which supports an array of unique plant and animal life. Definitions for Wetland Indicator Status Obligate Wetland (OBL) contain plants that almost always occur in wetlands (99% of the time) Facultative Wetland (FACW) contain plants that usually occur in wetlands (67-99% of the time) Facultative (FAC) includes plants that are just as likely to occur in wetland or non-wetland Look at % of plants to see if you have a wetland, no more trying to define water depth and water saturation questions to make determination. Wetland Indicator Status is the chance of a species being found in a wetland and non-wetland setting. It is primarily intended to assist professional wetland assessors identify wetland habitats and their boundaries based on the plants that are present, but will also be useful to anyone with an interest in wetland habitats and the plants that … all Strata are obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC) species, or a frequency analysis of all species within the community yields a prevalence index value Of less than 3.0 (where OBL = 1.0, FACW = 2.0, FAC = 3.0, FACU = 4.0, and UPL = 5.0). Green Star specializes in OBL, FACW, and FAC species. A wetland is a distinct ecosystem that is flooded by water, either permanently (for years or decades) or seasonally (for weeks or months).Flooding results in oxygen-free processes prevailing, especially in the soils.The primary factor that distinguishes wetlands from terrestrial land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the … Any plant not specifically listed is considered an upland plant except vines, aquatic plants and any plant species not introduced into the state of Florida as of the effective date of Chapter 62-340, F.A.C. The dominant plants of wetlands are monocotyledons. This big group of flowering plants includes grasses, reeds, rushes, sedges, New Zealand flax and cabbage trees.

The following listing is a selection of plants adapted to wetlands. For wetland professionals, the training also addressed whether each fern is an Obligate Wetland species, meaning that it always occurs in a wetland, also known as a hydrophyte (loves water); a Facultative Wetland species, which means that the fern usually shows up in a wetland, but can also be found in upland areas; or … See more. Plants on the vegetative index are specifically listed as obligate (OBL), facultative wet (FACW), and facultative (FAC). The New York Flora Atlas is a source of information for the distribution of plants within the state, as well as information on plant habitats, associated ecological communities, and taxonomy. Many plant and animal species live in the wetlands, including a number of rare and endangered species. The plants that grow in wetlands provide shelter from predators for prey species and nesting areas for birds, while the water gives fish and shellfish a place to spawn. Wetland Definition Chapter 62-340, F.A.C., Delineation of the Landward Extent of Wetlands and Surface Waters, provides a single methodology that is applicable statewide. This means that the majority of plant species growing in wetlands also grow in non-wetlands to some degree. Wetlands vary because of differences in hydrology, parent soil material, historical land use, topography and other factors. Wetland plants also need to remain stable in the soil if they deal with fast moving water that ebbs and flows. Indicator Plant List Wetlands Nova Scotia Environment.
