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 ...
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 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 .
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]
T. latifolia is an "obligate wetland" species, meaning that it is always found in or near water. [16] The species generally grows in flooded areas where the water depth does not exceed 0.8 m (2 + 1 ⁄ 2 ft), [17] but has also been reported growing in floating mats in slightly deeper water. [14]
They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages (such as killifishes) have however adapted to this habitat specifically. Vernal pools are a type of wetland.
Leucospora multifida is a facultative wetland or obligate wetland plant across its range. [9] It grows on sandy, gravelly, and marly soils in ditches, swales, and receding shorelines of rivers and streams. [2]
