Panicum Niihauense
''Panicum niihauense'' is a rare species of grass known by the common names ''lau 'ehu'' and Niihau panicgrass. It is endemic to Hawaii, where it has been found on the islands of Niihau and Kauai. It has not been observed on Niihau since 1949, and there are fewer than 40 individuals remaining on Kauai, not counting a few individuals that have been deliberately planted in appropriate habitat.USFWS''Panicum niihauense'' Five-year Review.January 2008. The grass is a federally listed endangered species of the United States. The only naturally occurring specimens of the grass grow in Polihale State Park. There they grow on sand dunes and they are threatened by the use of off-road vehicles.''Panicum niihauense''. The Nature Conservancy.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neop ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Endemic Flora Of Nihoa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Panicum
''Panicum'' (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known ''Panicum'' species include ''Panicum miliaceum'' (proso millet) and '' Panicum virgatum'' (switchgrass).

Verbesina Encelioides
''Verbesina encelioides'' is a flowering plant in the family Asteraceae. The species is native to many parts of the United States and Mexico Mexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatema .... It is naturalized in other parts of North America, the Middle East, Spain, Argentina, Australia and the Pacific islands. Common names include golden crownbeard, gold weed, wild sunflower, cowpen daisy, butter daisy, crown-beard, American dogweed and South African daisy. The species responds strongly to disturbances on suitable sites and retards the development of other local species. Research has identified an allelopathic effect on radishes which may explain its ability to dominate other species in some locations. It is a larval host for the bordered patch.The Xerces Society (2016), ' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Atriplex Semibaccata
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them. Description ''Atriplex semibaccata'' is a taproot perennial herb, that has prostrated and decumbent characteristics. Native to Australia and widespread in all mainland Australian states, ''A. semibaccata'' thrives in harsh and saline conditions. ''A. semibaccata'' is o ...

Prosopis Pallida
''Prosopis pallida'' is a species of mesquite tree. It has the common names kiawe () (in Hawaii), huarango (in its native South America) and American carob, as well as "bayahonda" (a generic term for ''Prosopis''), "algarrobo pálido" (in some parts of Ecuador and Peru), and "algarrobo blanco" (usually used for '' Prosopis alba''). It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast. While threatened in its native habitat, it is considered an invasive species in many other places. The kiawe is a spreading bush or moderately sized tree, bearing spines, spikes of greenish-yellow flowers, and long pods filled with small brown seeds. It is a successful invasive species due to its ability to reproduce in two ways: production of large numbers of easily dispersed seeds, and suckering to create thick monotypic stands that shade out nearby competing plants. It survives well in dry environments due to a long taproot which can reach deep ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...
