Pilbara Shrublands
The Pilbara shrublands is a deserts and xeric shrublands ecoregion in Western Australia. It is coterminous with the Pilbara IBRA region. For other definitions and uses of "Pilbara region" see Pilbara. Geography The Pilbara shrublands is bounded on the north by the Indian Ocean, and on the west, south, and east by other deserts and xeric shrubland ecoregions - the Carnarvon xeric shrublands to the west, the Western Australian mulga shrublands to the south, and the Great Sandy-Tanami desert to the east and northeast. The Pilbara geographic region covers most of the ecoregion, and extends east into the Great Sandy desert. The Hamersley Range, a region of mountain ranges and plateaus dissected by gorges, lies in the southern portion of the ecoregion. The Fortescue Plains extend east and west to the north of the Hamersley Range, forming the upper basin of the Fortescue River. The Chichester Plateau lies north of the Fortescue Plains. The Roebourne subregion encompasses the coas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamersley Range
The Hamersley Range is a mountainous region of the Pilbara region of Western Australia. The range was named on 12 June 1861 by explorer Francis Thomas Gregory after Edward Hamersley (senior), Edward Hamersley, a prominent promoter of his exploration expedition to the northwest. Juukan Gorge lies within the ranges, as does Karijini National Park (formerly known as Hamersley Range National Park). History The Aboriginal Australians, traditional Aboriginal owners of the area that the range runs through are the Kurrama people, Puutu Kunti Kurrama and Pinikura peoples. In 1999 a small range within the Hamersley was named the Hancock Range after the Hancock family, who were pioneers in the area. The Hancock range is east of Karijini National Park in a region of broad valleys and peaks that rise to almost . The Hancock Range is close to Mulga Downs Station, a property owned by the Hancock family and where Lang Hancock is buried. Geography The range runs from the Fortescue River in ...

Archean
The Archean Eon ( , also spelled Archaean or Archæan) is the second of four geologic eons of Earth's history, representing the time from . The Archean was preceded by the Hadean Eon and followed by the Proterozoic. The Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surfa ... during the Archean was mostly a water world: there was continental crust, but much of it was under an ocean deeper than today's ocean. Except for some trace minerals, today's oldest continental crust dates back to the Archean. Much of the geological detail of the Archean has been destroyed by subsequent activity. The Earliest known life forms, earliest known life started in the Archean. Life was simple throughout the Archean, mostly represented by shallow-water microbial mats called stromatolites, and the a ...

Erythrina
''Erythrina'' is a genus of plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, with the larger species growing up to in height. The generic name is derived from the Greek word , meaning "red", referring to the flower color of certain species. Names Particularly in horticulture, the name coral tree is used as a collective term for these plants. Flame tree is another vernacular name, but may refer to a number of unrelated plants as well. Many species of ''Erythrina'' have bright red flowers, and this may be the origin of the common name. However, the growth of the branches can resemble the shape of sea coral rather than the color of ''Corallium rubrum'' specifically, and this is an alternative source for the name. Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to i ...

Livistona Alfredii
''Livistona alfredii'', the millstream palm or millstream fan palm, is a species of flowering plant in the family Arecaceae. It is found only in the north-west of Western Australia where it is threatened by habitat loss. Description ''Livistona alfredii'' has cream flowers, flowers from July to September, and fruits from December to May. It is a dioecious palm, growing to 12 m, with prominent leaf scars. The petioles of dead leaves persist for the first metre, but shed higher up the stem. Fibres in the leaf-base are prominent, coarse, and persistent. The leaves are pale green-grey to glaucous on the upper surface, and light green-grey and waxy and dull on the lower surface. The inflorescences are unbranched at the base, and do not extend beyond the limit of the crown, but branch up to three orders. The flowers are solitary or in pairs, cylindrical in bud with triangular sepals. Distribution This palm is endemic to the north-west of Western Australia. It has been found in Bea ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Camaldulensis
''Eucalyptus camaldulensis'', commonly known as the river red gum, is a tree that is endemic to Australia. It has smooth white or cream-coloured bark, lance-shaped or curved adult leaves, flower buds in groups of seven or nine, white flowers and hemispherical fruit with the valves extending beyond the rim. A familiar and iconic tree, it is seen along many watercourses across inland Australia, providing shade in the extreme temperatures of central Australia.

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.

Acacia Aneura
''Acacia aneura'', commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia. It is the dominant tree in the habitat to which it gives its name ( mulga) that occurs across much of inland Australia. Specific regions have been designated the Western Australian mulga shrublands in Western Australia and Mulga Lands in Queensland. Description Mulga trees are highly variable, in form, in height, and in shape of phyllodes and seed pods. They can form dense forests up to high, or small, almost heath-like low shrubs spread well apart. Most commonly, mulgas are tall shrubs. Because the mulga is so variable, its taxonomy has been studied extensively, and although ''A. aneura'' is likely to be split into several species eventually, there is as yet no consensus on how or even if this should be done. Although generally small in size, mulgas are long-lived, a typical life span for a tree undisturbed by fire is of the order of 200 to 300 yea ...
