Usnea scabrida Taylor (1844) | |
Usnea scabrida is a foliose lichen that grows from holdfasts on trees. [1] [2] It occurs in southwest Western Australia. [3] It is a very pale grayish-yellowish green, slender, pendant, branching from the base, unequally branching, and shrubby. [3] The cortex contains usnic acid, and the medulla contains scabrosins. [4] The lichen was described as a new species in 1844 by English botanist Thomas Taylor. [5]
Usnea scabrida is endemic to Western Australia, South Australia, New South Wales and Victoria, but is also found outside Australia, [4] and in Queensland. [6] A subspecies Usnea scabrida subsp. elegans is found in eastern Australia. [7]
The Nightcap National Park is a national park situated within the Nightcap Range in the Northern Rivers region of New South Wales, Australia. The 8,080-hectare (20,000-acre) park was created in April 1983 and is situated 35 kilometres (22 mi) north of Lismore. The park was established following campaigns and blockades against logging at Terania Creek, Grier's Scrub and Mount Nardi between 1979 and 1982. Sections of the Whian Whian state forest were added to it following blockading and campaigning in 1998. The national park is classed by the IUCN World Commission on Protected Areas as Category II and is part of the Shield Volcano Group of the World Heritage Site Gondwana Rainforests of Australia inscribed in 1986 and added to the Australian National Heritage List in 2007.
Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations.
Usnea is a genus of mostly pale grayish-green fruticose lichens that grow like leafless mini-shrubs or tassels anchored on bark or twigs. The genus is in the family Parmeliaceae. It grows all over the world. Members of the genus are commonly called old man's beard, beard lichen, or beard moss.
Environmental issues in Australia describes a number of environmental issues which affect the environment of Australia. There are a range of such issues, some of the relating to conservation in Australia while others, for example the deteriorating state of Murray-Darling Basin, have a direct and serious effect on human land use and the economy.
Acacia alata is a shrub belonging to the genus Acacia.
Grevillea bipinnatifida, commonly known as fuchsia grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a spreading shrub, usually with bipinnatifid leaves and loose clusters of dull pink to crimson flowers.
Atriplex vesicaria, commonly known as bladder saltbush, is a species of flowering plant of the family Amaranthaceae and is endemic to arid and semi-arid inland regions of Australia. It is an upright or sprawling shrub with scaly leaves and separate male and female plants, the fruit often with a bladder-like appendage.

The Drummond Nature Reserve is an A class nature reserve 10 kilometres west of Bolgart, Western Australia. Named after the botanist James Drummond, the reserve has 439 species of vascular plants within its boundaries, including two rare and seven priority species.
Chrysocephalum semipapposum, commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. C. semipapposum produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. C. semipapposum is often confused with Chrysocephalum apiculatum or 'yellow buttons', due to their similar appearances. C. semipapposum has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. C. semipapposum is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered everlasting has many uses, including as a source of nectar for butterflies, cut flowers or as an addition to a garden.
Eucalyptus wandoo, commonly known as wandoo, dooto, warrnt or wornt and sometimes as white gum, is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar Eucalyptus species known as wandoo.
Dysoxylum mollissimum subsp. molle, the red bean or Miva mahogany, is a rainforest tree in the family Meliaceae. It occurs in tropical, sub-tropical and littoral rainforests in eastern Australia, as far southwards as north-eastern New South Wales. Also occurs in Malesia and the south-western Pacific Islands. In Australia it is distributed from the Bellinger River in New South Wales in the south, to the wet tropics of north-eastern Queensland. The specific epithet mollissimum is from the Latin, meaning "very soft", describing the soft hairy leaflets. A signposted red bean tree may be seen near the car park of Victoria Park Nature Reserve in north-eastern New South Wales.
Eucalyptus spathulata, commonly known as swamp mallet, narrow leaved gimlet or swamp gimlet, is a species of mallet that is endemic to Western Australia. It has a dense crown, smooth, satin-like bark, glossy green, linear leaves, flower buds in groups of three or seven, white flowers and cup-shaped to conical fruit.
Persoonia terminalis, also known as the Torrington geebung, is a shrub belonging to the family Proteaceae, and native to northern New South Wales and southern Queensland in eastern Australia. Reported as a subspecies of Persoonia nutans in 1981, it was described as a species by Lawrie Johnson and his colleague Peter Weston in 1991.
Eucalyptus pruinosa, commonly known as silver box, silver leaf box, apple box or smoke tree, is a species of tree or a mallee that is endemic to northern Australia. The Jaminjung peoples know the tree as yarrirra or jarnbiny, the Jaru as wararn and the Wagiman as wararn. It has rough, fibrous to flaky bark on the trunk and branches, a crown composed of juvenile, glaucous, heart-shaped to broadly elliptical leaves arranged in opposite pairs, flower buds arranged in groups of seven on the ends of branches, creamy white to pale yellow flowers and cylindrical to conical fruit.
Usnea trichodea, commonly known as bony beard lichen, is a pale straw-colored fruticose lichen with a pendant growth form. It grows on trees and is native to eastern North America.
Cladia beaugleholei is a lichen in the family Cladoniaceae, found in Australia. It was first described as Heterodea beaugleholei in 1978 by Rex Filson, from a specimen collected from forest soil in New South Wales. The species epithet honours Alexander Clifford Beauglehole. It was reassigned to the genus, Cladia by Sittiporn Parnmen and H. Thorsten Lumbsch in 2012.
Xanthoparmelia semiviridis, also known as resurrection lichen is a foliose lichen species in the family Parmeliaceae. Its common name comes from the reaction of a dry sample to moisture. In its dry state it appears like curled-up dry leaf litter on the ground, but after rainfall the lichen will quickly recover, unfurl and become darker in colour. It is found in semi-arid areas across southern Australia and the South Island of New Zealand. The species is in decline in New Zealand because of the loss of habitat resulting from the establishment of dairy farms and vineyards in former indigenous habitat, and the deterioration of existing habitat caused by invasive species such as hawkweeds.
Pimelea leptostachya is a species of flowering plant in the family Thymelaeaceae and is endemic to central Queensland. It is a shrub with narrowly elliptic leaves and spikes of maroon or yellow, tube-shaped flowers arranged in groups of 13 to 23.
