Victoria Plains Tropical Savanna
The Victoria Plains tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northwestern Australia. Geography The ecoregion lies in the central Northern Territory, extending into northeastern Western Australia. It forms a transition between the tropical savannas of northern Australia and the Australia's interior deserts. The Bungle Bungle Range is in the ecoregion. It is bounded on the northwest and north by the Kimberley tropical savanna, on the northeast and east by the Carpentaria tropical savanna, and on the southeast by the Mitchell Grass Downs. The Great Sandy-Tanami desert ecoregion lies to the south. The western portion of the ecoregion, known as the Ord Victoria Plain, is drained by the upper Ord and Victoria rivers. IBRA regions The ecoregion encompasses the Ord Victoria Plain and Sturt Plateau IBRA regions. Climate The ecoregion has a tropical savanna climate. Monthly average maximum temperatures range from 25º to 35º C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purnululu National Park
The Purnululu National Park is a World Heritage Site in the East Kimberley region of Western Australia. The national park is located approximately south of Kununurra, with Halls Creek located to the south. Declared a World Heritage Site in 2003, the park was inscribed as follows: Purnululu National Park World Heritage site The World Heritage status of the region was created and negotiated in 2003, and the adopted boundary of the existing national park. Since its listing, the Government of Western Australia has reserved additional areas located adjacent to the World Heritage Area, including the Purnululu Conservation Park and the Ord River Regeneration Reserve. The site was gazetted on the Australian National Heritage List on 21 May 2007 under the .

Tropical Savanna Climate
Tropical savanna climate or tropical wet and dry climate is a tropical climate sub-type that corresponds to the Köppen climate classification categories ''Aw'' (for a dry winter) and ''As'' (for a dry summer). The driest month has less than of precipitation and also less than 100-\left (\frac \right)mm of precipitation. This latter fact is in a direct contrast to a tropical monsoon climate, whose driest month sees less than of precipitation but has ''more'' than 100-\left (\frac \right) of precipitation. In essence, a tropical savanna climate tends to either see less overall rainfall than a tropical monsoon climate or have more pronounced dry season(s). In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year. Tropical savanna climates often feature tree-studded grasslands due to its dryness, rather than thick jungle. It is this widespread occurrence of tall, coarse grass (called savanna) which has led to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astrebla
''Astrebla'' is a small genus of xerophytic (adapted to survive in an environment with little liquid water) grasses found only in Australia. They are the dominant grass across much of the continent. They are commonly known as Mitchell grass after Scottish explorer, Thomas Mitchell (1792-1855), who first collected a specimen near Bourke in New South Wales. Mitchell grasses grow on clay soils, mainly between an upper limit of and a lower limit of average annual rainfall, and at even lower rainfall in depressions where the water concentrates following rains, for example in Sturt's Stony Desert. Mitchell grasses are deep-rooted and become dormant during drought, allowing them to survive extended periods without rainfall. They are commonly found clumped together and reaching one metre high, providing habitat for organisms such as mammals. ; Species See also * List of Poaceae genera The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species ...

Bauhinia
''Bauhinia'' () is a large genus of flowering plants in the subfamily Cercidoideae and tribe Bauhinieae, in the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers Gaspard and Johann, Swiss- French botanists. Many species are widely planted in the tropics as orchid trees, particularly in India, Sri Lanka, Vietnam, Nepal and southeastern China. Other common names include mountain ebony and ''kachnar''. Before the family was reorganised, a number of genera including the lianas ''Lasiobema'' and ''Phanera'' were placed here (see related genera). In the United States, the trees grow in Hawaii, coastal California, Arizona, Texas, Louisiana, and Florida. There are native species, like ''Bauhinia lunarioides'' native to Texas and widely planted in the Southwest as a landscape plant. ''Bauhinia'' × ''blakeana'' is the floral emblem of Hong Kong—a stylized orchid tree flower appears on the flag of Hong Kong and Ho ...

Aristida
''Aristida'' is a very nearly cosmopolitan genus of plants in the grass family. ''Aristida'' is distinguished by having three awns (bristles) on each lemma of each floret. The genus includes about 300 species found worldwide, often in arid warm regions. This genus is among those colloquially called three-awns wiregrasses, speargrasses and needlegrasses. The name ''Aristida'' is derived from the Latin " arista", meaning "awn". They are characteristic of semiarid grassland. The Wiregrass Region of North America is named for '' A. stricta''. Other locales where this genus is an important component of the ecosystem include the Carolina Bays, the sandhills of the Carolinas, and elsewhere, Mulga scrub in Australia, and the xeric grasslands around Lake Turkana in Africa. Local increases in the abundance of wiregrasses is a good indicator of overgrazing, as livestock avoid them. Description ''Aristida'' stems are ascending to erect, with both basal and cauline leaves.
