Eucalyptus Dolorosa
''Eucalyptus dolorosa'', commonly known as the Mount Misery mallee or Dandaragan mallee, is a species of eucalypt that is endemic to Western Australia. It is a mallee with a short skirt of rough flaky bark at the base of the trunk, smooth pale greyish brown above, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and cup-shaped to spherical fruit. Description ''Eucalyptus dolorosa'' typically grows to a height of and forms a lignotuber. The bark on the lower of the trunk is rough flaky and grey to yellowish brown, smooth, pale grey-brown above. Young plants and coppice regrowth have leaves arranged alternately, egg-shaped to lance-shaped, long, wide and petiolate. Adult leaves are glossy green, arranged alternately, lance-shaped to curved long and wide with a pointed apex and a base tapering to a petiole long.

Ian Brooker
Murray Ian Hill Brooker AM (2 June 1934 – 25 June 2016), better known as Ian Brooker, was an Australian botanist. He was widely recognised as the leading authority on the genus ''Eucalyptus''. Ian Brooker was born in Adelaide, South Australia on 2 June 1934. He obtained a B.Ag.Sc. from the University of Adelaide, and a MSc and D.Sc. from the Australian National University in Canberra. He worked with the Soil Conservation Branch of the Department of Agriculture in South Australia from 1957 to 1963; then joined the Department of Botany at the Australian National University until 1969; and then spent a year with the Western Australian Herbarium. In 1970, Brooker joined the Forest Research Institute in Canberra, now part of CSIRO. His research since then has specialised in the genus ''Eucalyptus'', especially its taxonomy. He travelled widely throughout Australia collecting specimens, and published 100 research papers, 180 leaflets, and four books, and is the principal author o ...

Eucalyptus Platydisca
''Eucalyptus platydisca'', also known as Jimberlana mallee, is a species of eucalypt native to Western Australia.

Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

Mallee Woodlands And Shrublands
Mallee Woodlands and Shrublands is one of 32 Major Vegetation Groups defined by the Australian Government Department of the Environment and Energy. Description " Mallee" refers to the growth habit of a group of (mainly) eucalypt species that grow to a height of , have many stems arising from a lignotuber and have a leafy canopy that shades 30–70% of the ground. The term is also applied to a vegetation association where these mallee eucalypts grow, on land that is generally flat without hills or tall trees and where the climate is semi-arid. Of the 32 Major Vegetation Groups classified under the National Vegetation Information System, "Mallee Woodlands and Shrublands" (MVG14): * are semi-arid areas dominated by mallee eucalypts; * may also have co-dominant species of '' Callitris'', '' Melaleuca'', ''Acacia'' and ''Hakea''; * have an open tree or shrub layer with more than 10% foliage cover and more than 20% crown cover, distinguishing MVG 14 from "Mallee Open Woodland" (MVG14 ...

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Dandaragan, Western Australia
Dandaragan is a small town in the Wheatbelt region of Western Australia. The name of Dandaragan was first recorded in 1850 as the name of a nearby gulley and spring or watering hole known as Dandaraga spring. The word is Indigenous Australian in origin and is thought to mean ''good kangaroo country''. The first recorded land lease was to William Brockman in 1848; he had a land lease at Muchamulla Springs. James Drummond settled in the area in 1850 and established a farm. A police station was built later and the townsite was gazetted in 1958.

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...
