Orchids Of Western Australia
Among the many wildflowers in Western Australia, there are around four hundred species of orchids. Early identifications One of the first botanists to study Western Australia was Archibald Menzies, aboard HMS ''Discovery'', who explored King George Sound in 1791. Many of the samples (including orchids) were lost in the return to England, but those that did survive were documented in ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', published by Robert Brown in 1810. The first three orchids from Western Australia to be named were ''Caladenia menziesii'' (now '' Leptoceras menziesii''), '' Caladenia flava'', and ''Diuris longifolia''. In 1802 Robert Brown himself collected 500 specimens of flora from Western Australia, including: * ''Diuris emarginata'' var. ''emarginata'' * ''Diuris emarginata'' var. ''pauciflora'' *'' Diuris setacea'' *'' Epiblema grandiflorum'' *''Microtis alba'' *'' Microtis media'' *'' Microtis pulchella'' *'' Prasophyllum gibbosum'' *''Prasoph ...

Endemic Orchids Of Australia
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] |
Caladenia
''Caladenia'', commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state. Description Orchids in the genus ''Caladenia'' are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous sheath. The tuber produces two "droppers" which become daughter tubers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Parks And Wildlife (Western Australia)
The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the ''Conservation and Land Management Act 1984'' and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment. History The Department of Environment and Conservation (DEC) was separated on 30 June 2013, forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), both of which commenced operations on 1 July 2013. DPaW focused on managing multiple use state forests, national parks, marine parks and reserves. DER focused on environmental regulation, approvals and appeals processes, and pollution prevention. It was announced on 28 April 2017 that the Department of Parks and Wildlife would merge with the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rott ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

Allocasuarina Huegeliana
''Allocasuarina huegeliana'', commonly known as rock sheoak or sighing sheoak, is a tree in the family Casuarinaceae. Endemic to Western Australia, it occurs mostly throughout the Wheatbelt region. It is now especially common on road verges, where it sometimes forms thickets. Description Rock sheoak is a dioecious tree that grows to a height of . The dark coloured bark is longitudinally fissured. It has sparse foliage that forms a rounded outline. Sometimes it branches at ground level, but usually has a bole of a few metres. As with other ''Allocasuarina'' species, the foliage consists of slender green branchlets informally referred to as "needles" but more correctly termed cladodes. These are segmented, and the true leaves are reduced to tiny teeth encircling each joint. Male trees have small brown flower spikes at the end of branchlets. Female trees bear small flowers on short branchlets of their own. The red to brown coloured flowers appear between May and January. Fer ...

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest. Considerable amount of research delineates northern, central and southern jarrah forestStrelein, G. J. (1988) ''Site classification in the Southern jarrah forest of Western Australia'' Como, W.A.
