Eucalyptus is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts or "gum trees". Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, the leaves have oil glands, and the sepals and petals are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Eucalyptus marginata, commonly known as jarrah, djarraly in Noongar language and historically as Swan River mahogany, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers.
Eucalyptus regnans, known variously as mountain ash, swamp gum, or stringy gum, is a species of medium-sized to very tall forest tree that is native to the Australia states of Tasmania and Victoria. It is a straight-trunked tree with smooth grey bark, but with a stocking of rough brown bark at the base, glossy green, lance-shaped to curved adult leaves, flower buds in groups of between nine and fifteen, white flowers, and cup-shaped or conical fruit. It is the tallest of all flowering plants; the tallest measured living specimen, named Centurion, stands 100 metres tall in Tasmania.
An old-growth forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris.
Sustainable forest management (SFM) is the management of forests according to the principles of sustainable development. Sustainable forest management must keep a balance between the three main pillars: ecological, economic and socio-cultural. The goal of sustainable forestry is to allow for a balance to be found between making use of trees while maintaining natural patterns of disturbance and regeneration. The forestry industry mitigates climate change by boosting carbon storage in growing trees and soils and improving the sustainable supply of renewable raw materials via sustainable forest management.
Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.
Social forestry is the management and protection of forests and afforestation of barren and deforested lands with the purpose of helping environmental, social and rural development. The term social forestry was first used in 1976 by The National Commission on Agriculture, when the government of India aimed to reduce pressure on forests by planting trees on all unused and fallow lands. It was intended as a democratic approach to forest conservation and usage, maximizing land utilization for multiple purposes.
Forestry Tasmania trades as Sustainable Timber Tasmania but is still legally called Forestry Tasmania. It is a government business enterprise wholly owned by the Government of Tasmania, Australia. It is responsible for the management of public production forest in Tasmania, which is about 800,000 hectares of crown land that is classified as 'permanent timber production zone'.
Armillaria luteobubalina, commonly known as the Australian honey fungus, is a species of mushroom in the family Physalacriaceae. Widely distributed in southern Australia, the fungus is responsible for a disease known as Armillaria root rot, a primary cause of Eucalyptus tree death and forest dieback. It is the most pathogenic and widespread of the six Armillaria species found in Australia. The fungus has also been collected in Argentina and Chile. Fruit bodies have cream- to tan-coloured caps that grow up to 10 cm (4 in) in diameter and stems that measure up to 20 cm (8 in) long by 1.5 cm (1 in) thick. The fruit bodies, which appear at the base of infected trees and other woody plants in autumn (March–April), are edible, but require cooking to remove the bitter taste. The fungus is dispersed through spores produced on gills on the underside of the caps, and also by growing vegetatively through the root systems of host trees. The ability of the fungus to spread vegetatively is facilitated by an aerating system that allows it to efficiently diffuse oxygen through rhizomorphs—rootlike structures made of dense masses of hyphae.
Quamby Bluff is a mountain in Northern Tasmania, Australia that is an outlying part of the Great Western Tiers mountain range.
Eucalyptus nitens, commonly known as shining gum or silvertop, is a species of tall tree native to Victoria and eastern New South Wales. It has smooth greyish bark, sometimes with thin, rough bark near the base, lance-shaped adult leaves, flower buds in groups of seven or nine, white flowers and cup-shaped, barrel-shaped or cylindrical fruit. It grows in wet forests and rainforest margins on fertile soils in cool, high-rainfall areas.
The Brown Mountain forest is located in East Gippsland, Victoria (Australia), and is notable for containing large tracts of old growth forest, including over fifty shining gum trees estimated to be over 300 years old.
Eucalyptus loxophleba, commonly known as York gum, daarwet, goatta, twotta or yandee, is a species of tree or mallee that is endemic to Western Australia. It has rough bark on the trunk, smooth olive to brownish bark above, lance-shaped adult leaves, flowers buds in groups of between seven and eleven, white flowers and conical fruit.
Eucalyptus pulchella, commonly known as the white peppermint or narrow-leaved peppermint, is a species of small to medium-sized tree that is endemic to Tasmania. it has smooth bark, sometimes with rough fibrous bark on older trees, linear leaves, flower buds in groups of nine to twenty or more, white flowers and cup-shaped to shortened spherical fruit.
Private Forests Tasmania is a Tasmanian government statutory authority established in 1994 by the Tasmanian Private Forests Act 1994. The Authority was created to provide assistance and advice on private forest management in Tasmania, Australia. The objectives of the authority are to facilitate and expand the development of the private forest resource in Tasmania, in a manner that is consistent with sound forest land management practices.
A private timber reserve is an area of privately owned land, used or intended to be used, for growing timber within the Australian state of Tasmania.
Eucalyptus urnigera, commonly known as urn tree, is a species of small to medium-sized tree that is endemic to Tasmania. It has smooth bark, lance-shaped or elliptical leaves, flower buds in groups of three, white flowers and urn-shaped fruit.
The Forests Commission Victoria (FCV) was the main government authority responsible for management and protection of State forests in Victoria, Australia between 1918 and 1983.
A tree plantation, forest plantation, plantation forest, timber plantation or tree farm is a forest planted for high volume production of wood, usually by planting one type of tree as a monoculture forest. The term tree farm also is used to refer to tree nurseries and Christmas tree farms.
The Milnthorpe Model describes a situation where fast-growing non-indigenous trees such as eucalypts, are used to colonise ex-pasture in order to establish a forested environment where indigenous canopy species can thrive.
