The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amorpha
''Amorpha'' is a genus of plants in the pea family, Fabaceae. All the species are native to North America, from southern Canada, most of the United States (US), and northern Mexico. They are commonly known as false indigo. The name ''Amorpha'' means "deformed" or "without form" in Greek and was given because flowers of this genus only have one petal, unlike the usual "pea-shaped" flowers of the Faboideae subfamily. ''Amorpha'' is missing the wing and keel petals. The desert false indigo or indigo bush (''Amorpha fruticosa''), is a shrub that grows from 3 m to 5 m tall. The species is considered a rare species in the US state of West Virginia and in the Canadian provinces of Manitoba and Ontario, but is considered an invasive plant in some areas of the northeastern and northwestern United States and in southeastern Canada, beyond its native range, and has also been introduced into Europe. The lead plant ('' Amorpha canescens''), a bushy shrub, is an important North A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaura Demareei
''Gaura'' is a genus of flowering plants in the family Onagraceae, native to North America. The genus includes many species known commonly as beeblossoms. Recent genetic research has shown that the genus is paraphyletic unless the monotypic genus ''Stenosiphon'' is included within ''Gaura'', increasing the number of species in the genus to 22.Raven P. H., & Gregory, D. P. (1972). A revision of the genus Gaura (Onagraceae). ''Mem. Torrey Bot. Club'' 23: 1-96.Carr, B. L., Crisci, J. V., & Hoch, P. C. (1990).

Calamovilfa Arcuata
''Calamovilfa arcuata'', commonly known as Cumberland sandreed, is a species of flowering plant in the grass family. It is native to the southeastern United States, where it is found in river scour zones. Due to its specialized habitat, it has a highly localized range, found only on the Cumberland Plateau and in the Ouachita Mountains. Natural history This species is found only is a specialized riverine habitat that is kept open by extreme flood scouring events. These flood events naturally occur in high-gradient, rocky rivers, which results in the prevention of large tree growth. This species takes advantage of the prairie-like openings these floods create. Due to its specialized habitat, and low density of populations, ''Calamovilfa arcuata'' is considered imperiled. On the Cumberland Plateau, it is most often found on sandstone cobble where it co-occurs with two other rare plants that are also restricted to this habitat: ''Conradina verticillata'' (Cumberland rosemary) and '' S ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Wherev ...
