Corymbia Calophylla – Xanthorrhoea Preissii Woodlands And Shrublands Of The Swan Coastal Plain
''Corymbia calophylla'' – ''Xanthorrhoea preissii'' woodlands and shrublands of the Swan Coastal Plain is an ecological community in the Southwest Australia ecoregion. The assemblage, found inland on the eastern side of the Swan Coastal Plain, is defined by the presence of plant species at drier or lower rainfall areas of heavy soils dominated by several marri communities. The mid and upper story vegetation is the marri tree, ''Corymbia calophylla'', and the grasstree ''Xanthorrhoea preissii'', called balga. Marri is also found in two other described ecological communities which contain some plants of the assemblage, those in wetter areas of the range with a greater diversity of plants. The locations of these communities is a remnant of a previously greater range, having been reduced by possibly over 97%. The community is recognised by an association of species: trees are ''Corymbia calophylla'' and occasional ''Eucalyptus wandoo''; shrubs are '' Acacia pulchella'', '' Dryandra ...

Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot, as well as Kwongan. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20-120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isopogon Drummondii
''Isopogon drummondii'' is a small shrub of the family Proteaceae and is endemic to the southwest of Western Australia. It was first formally described in 1843 by Henri Antoine Jacques in ''Annales de Flore et de Pomone'' from an unpublished description by Hügel. In 1870, George Bentham described ''I. drummondii'' in ''Flora Australiensis'' but since the name had already been used for a different species, Bentham's name was a Nomen illegitimum. In a 2019 paper in the journal ''Nuytsia'', Barbara Lynette Rye and Terry Desmond Macfarlane proposed that ''I. drummondii'' is a synonym of ''Isopogon sphaerocephalus'' subsp. ''spaerocaphalus''. Rye and Macfarlane also proposed that Bentham was not aware of Jacques's ''I. drummondii'' because the description had been published in a horticultural magazine, from specimens grown in a greenhouse in France. They suggested the new name ' Isopogon autumnalis'' for Bentham's ''I. drummondii'' and that since Lindley's ''I. sphaerocaphalus'' ...

Western Swamp Tortoise
The western swamp turtle or western swamp tortoise (''Pseudemydura umbrina'') is a critically endangered species of freshwater turtle endemic to a small portion of Western Australia. It is the only member of the genus ''Pseudemydura'' in the monotypic subfamily Pseudemydurinae. It is the sister taxon to the subfamily Chelodininae. As a consequence of the greatly altered habitat in the area in which it occurs near Perth, Western Australia, it exists in small fragmented populations, making the species critically endangered. Taxonomy The accepted description of the species by Friedrich Siebenrock was published in 1901. The first specimen of the western swamp tortoise was collected by Ludwig Preiss in 1839 and sent to Vienna Museum. There it was labelled "New Holland" and was named ''Pseudemydura umbrina'' 1901 by Seibenrock. No further specimens were found until 1953. In 1954, Ludwig Glauert named these specimens ''Emydura inspectata'', but in 1958, Ernest Williams of Harvard Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herbaceous Plants
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts of ...
