Total employment in forestry and logging in Australia (thousands of people) since 1984

Australia has many forests of importance due to significant features, despite being one of the driest continents. Australia has approximately 123 million hectares of native forest, which represents about 60% of Australia's land area. [1] The majority of Australia's trees are hardwoods, typically eucalypts, rather than softwoods like pine. While softwoods dominate some native forests, their total area is judged insufficient to constitute a major forest type in Australia's National Forest Inventory. The Forests Australia website provides up-to-date information on Australia's forests. Detailed information on Australia's forests is available from Australia's State of the Forests Reports that are published every five years.

Australia Country in Oceania

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth and Adelaide.

Hectare metric unit of area

The hectare is an SI accepted metric system unit of area equal to a square with 100-metre sides, or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres.

Forest types

There are 457 forest communities distributed across Australia. These have been grouped into the following seven native forest types, which are characterised by dominant species and the structure of the forest:

Rainforest type of forest with high rainfall

Rainforests are forests characterized by high rainfall, with annual rainfall in the case of tropical rainforests between 250 and 450 centimetres, and definitions varying by region for temperate rainforests. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests.

<i>Melaleuca</i> genus of plants

Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees. They range in size from small shrubs that rarely grow to more than 1 m high, to trees up to 35 m. Their flowers generally occur in groups, forming a “head” or “spike” resembling a brush used for cleaning bottles, containing up to 80 individual flowers. They are superficially like Banksia species, which also have their flowers in a spike, but the structures of individual flowers in the two genera are very different.

Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera found across Australasia: Eucalyptus, Corymbia, Angophora, Stockwellia, Allosyncarpia, Eucalyptopsis and Arillastrum.

Plantation forests (softwood and hardwood) have been defined as an eighth group that covers trees planted for commercial use.

Government

Policies

In Australia the states and territories are responsible for managing forests. [2] Guidance is primarily provided by the 1992 National Forest Policy Statement (NFPS). [3] The NFPS allows for the inclusion of Regional Forest Agreements, which are 20-year plans for the management of native forests.

The Regional Forest Agreements (RFA) are 20 year plans for the conservation and sustainable management of Australia's native forests, and are intended to provide certainty to commercial forestry operations while protecting environmental values. The 10 RFA's were progressively signed between 1997 and 2001. The RFA process grew out of the 1992 National Forest Policy Statement.

Departments

The New South Wales Department of Primary Industries, a division of the New South Wales Government, is responsible for the administration and development for agriculture, fisheries, aquaculture, forestry, and biosecurity in New South Wales. The Department works to drive innovation in primary industries to improve resilience, productivity and sustainability, and to ensure risks are managed for natural resources, farming and food.

South Australian Forestry Corporation is a business enterprise owned by the Government of South Australia which is responsible for management of publicly owned plantation forests in South Australia including the commercial production of timber and the management of forests for non-commercial purposes such as community use and as protected areas.

The Department of Environment and Primary Industries (DEPI) was a state government department responsible for protecting the environment, boosting productivity in Victoria's food and fibre sector, management of natural resources and managing water resources in the state of Victoria, Australia. It was created in April 2013 by merging the Department of Primary Industries with the Department of Sustainability and Environment.

Fauna of Australia

The fauna of Australia consists of a huge variety of animals; some 83% of mammals, 89% of reptiles, 90% of fish and insects and 93% of amphibians that inhabit the continent are endemic to Australia. This high level of endemism can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time. A unique feature of Australia's fauna is the relative scarcity of native placental mammals. Consequently, the marsupials — a group of mammals that raise their young in a pouch, including the macropods, possums and dasyuromorphs — occupy many of the ecological niches placental animals occupy elsewhere in the world. Australia is home to two of the five known extant species of monotremes and has numerous venomous species, which include the platypus, spiders, scorpions, octopus, jellyfish, molluscs, stonefish, and stingrays. Uniquely, Australia has more venomous than non-venomous species of snakes.

Flora of Australia

The flora of Australia comprises a vast assemblage of plant species estimated to over 20,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.

National Reserve System Protected area in Australia

Australia's National Reserve System (NRS) is a network of more than 10,000 Commonwealth plus state and territory protected areas which, in combination, on a national scale, protect more than 137 million hectares unique biodiversity and most significant ecological landscapes for future generations. The aim of the NRS is protect the diversity of all native landscapes, flora and fauna across Australia through strategic habitat protection.

<i>Eucalyptus</i> genus of plants

Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is smooth, fibrous or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Australia is covered by 92,000,000 hectares of eucalypt forest, comprising three quarters of the area covered by native forest.

Alpine National Park Protected area in Victoria, Australia

The Alpine National Park is a national park located in the Central Highlands and Alpine regions of Victoria, Australia. The 646,000-hectare (1,600,000-acre) national park is located northeast of Melbourne. It is the largest National Park in Victoria, and covers much of the higher areas of the Great Dividing Range in Victoria, including Victoria's highest point, Mount Bogong at 1,986 metres (6,516 ft) and the associated subalpine woodland and grassland of the Bogong High Plains. The park's north-eastern boundary is along the border with New South Wales, where it abuts the Kosciuszko National Park. On 7 November 2008 the Alpine National Park was added to the Australian National Heritage List as one of eleven areas constituting the Australian Alps National Parks and Reserves.

Hartz Mountains National Park Protected area in Tasmania, Australia

Hartz Mountains National Park is located in the south of Tasmania, Australia. It is one of 19 Tasmanian National Parks, and in 1989 it was included in the Tasmanian Wilderness World Heritage Area, in recognition of its natural and cultural values. The Hartz Mountains were named after the Harz mountain range in Germany.

<i>Eucalyptus regnans</i> species of plant

Eucalyptus regnans, known variously as mountain ash, swamp gum, or stringy gum, is a species of Eucalyptus native to Tasmania and the state of Victoria in southeastern Australia. It is the tallest flowering plant and one of the tallest trees in the world, second only to the coast redwood of North America. A straight-trunked tree with smooth grey bark, but with a stocking of rough brown bark from 5 to 20 metres above the ground, it regularly grows to 85 metres (280 ft), with the tallest living specimen, the Centurion in Tasmania, standing 100.5 metres tall. White flowers appear in autumn. Victorian botanist Ferdinand von Mueller described the species in 1871.

Leadbeaters possum species of mammal

The Leadbeater's possum is a critically endangered possum largely restricted to small pockets of alpine ash, mountain ash, and snow gum forests in the Central Highlands of Victoria, Australia, north-east of Melbourne. It is primitive, relict, and non-gliding, and, as the only species in the petaurid genus Gymnobelideus, represents an ancestral form. Formerly, Leadbeater's possums were moderately common within the very small areas they inhabited; their requirement for year-round food supplies and tree-holes to take refuge in during the day restricts them to mixed-age wet sclerophyll forest with a dense mid-story of Acacia. The species was named in 1867 after John Leadbeater, the then taxidermist at the Museum Victoria. They also go by the common name of fairy possum. On 2 March 1971, the State of Victoria made the Leadbeater's possum its faunal emblem.

Temperate rainforest

Temperate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive heavy rainfall.

Old-growth forest A forest that has attained great age without significant disturbance

An old-growth forest — also termed primary forest or late seral forest — is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. 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.

Styx Valley a valley on the island of Tasmania, Australia

Central Highlands (Victoria) region of Victoria, Australia

The Central Highlands is a region of Victoria. This term is mainly used in a geological context to describe the part of the Great Dividing Range in Victoria that is outside the Alpine areas. The area is situated east of Ballarat, south of Bendigo, north and east of Melbourne, west of the Alpine areas and includes the Great Dividing Range. Major towns of the highlands include Castlemaine, Creswick, Daylesford, Gisborne, Kyneton and Woodend. All these towns are located in the western part of the Central Highlands usually referred to as the West Central Highlands. The eastern part of the Central Highlands referred to as the East Central Highlands also contains areas of rainforest.
