Obligate upland (UPL) - Almost always occurs in non-wetlands under natural conditions (estimated probability > 99%). A positive (+) or negative (−) sign is used for the facultative categories. The (+) sign indicates a frequency towards the wetter end of the category (more frequently found in wetlands) and the (−) sign indicates a frequency ...
Wetland indicator status denotes the probability of individual species of vascular plants occurring in freshwater, brackish and saltwater wetlands in the United States. The wetland status of 7,000 plants is determined upon information contained in a list compiled in the National Wetland Inventory undertaken by the U.S. Fish and Wildlife Service and developed in cooperation with a federal inter ...
While many Obligate Wetland (OBL) species do occur in permanently or semi-permanently flooded wetlands, there are also a number of obligates that occur in and temporary or seasonally flooded wetlands. A few species are restricted entirely to these transient-type wetland environments.
It is an obligate wetland species and grows as an emergent species in the Everglades. In the absence of fire, S. caroliniana can convert herbaceous wetlands to forested wetlands. Salix caroliniana flowers in the early spring, either before or together with the emergence of leaves.
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". [15]
Chamaecyparis thyoides lives almost exclusively in freshwater wetlands and is considered an obligate wetland species. It prefers habitats where the soil is saturated with water at least during the majority of the growing season.
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil .
It is an obligate wetland plant and able to grow in saturated soils. [2] Saururus cernuus is a herbaceous perennial that gets its most frequent common name, lizard's tail, from its white flowers that bloom in the summer months. [2] The inflorescence is usually 6 to 8 in long. [3]
