Ravensthorpe, Western Australia
Ravensthorpe is a town 541 km south-east of Perth and 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the , Ravensthorpe had a population of 438. In 1848, the area was surveyed by Surveyor General John Septimus Roe who named many of the geographical features nearby, including the nearby Ravensthorpe Range that the later town was named after. There was one of the Western Australian Government Railways isolated branch lines between Hopetoun and Ravensthorpe. This line opened in 1909. Alluvial gold was discovered at the Phillips River in 1892. At the goldfield a ''de facto'' town emerged, known as ''Phillips River''. The government completed construction of a copper and gold smelter about 2 km south east of the town in 1906, used to cast copper and gold ingots. History A temporary pastoral lease ("Free Run") was registered by James Dunn senior in 1868. His five sons and daughter started s ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non- magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Salmon Gums, Western Australia
Salmon Gums is a small town in Western Australia located 106 km north of Esperance on the Coolgardie-Esperance Highway. The name is derived from a prominent stretch of '' Eucalyptus salmonophloia'' (Salmon Gum) trees which formed a landmark in the town's early days. The town is part of the Shire of Esperance. At the 2016 census, Salmon Gums had a population of 191. The surrounding areas produce wheat and other cereal crops. The town is a receival site for Cooperative Bulk Handling. History The first potential use of a townsite was as a watering spot for the proposed Esperance to Norseman Railway, since Salmon Gums is roughly halfway between these two towns. Land for a town-site was set aside in 1912 and the name was recommended in 1916. This land lay within the tribal boundaries of the indigenous Kalaako. The town was gazetted in 1925, when the Esperance to Salmon Gums section of the railway was completed. Settlement of the area received a boost after the First Wor ...

Stirling Range
The Stirling Range or Koikyennuruff is a range of mountains and hills in the Great Southern region of Western Australia, south-east of Perth. It is over wide from west to east, stretching from the highway between Mount Barker and Cranbrook eastward past Gnowangerup. The Stirling Range is protected by the Stirling Range National Park, which was gazetted in 1913, and has an area of . Environment Geology The mountains are formed of metamorphic rock derived from quartz sandstones and shales deposited during the Paleoproterozoic Era, between 2,016 and 1,215 million years ago (based on U-Th-Pb isotope geochronology of monazite crystals). The sediments were subsequently metamorphosed 1,215 million years ago, and later folded during reactivation of basement structures recording lateral displacements between Antarctica and Australia. Despite the relative youth of the mountains, the soils remain very poor, creating the species-rich heathland flora. Climate As the only ver ...
