Australia's forests – overview

Australia has 125 million hectares of forest, which is 16 per cent of Australia’s land area. This is about 3 per cent of the world’s forest area, and the seventh-largest reported forest area worldwide.

Australia’s forests are recognised and valued for their diverse ecosystems and unique biodiversity and for their provision of products such as wood. They perform important environmental functions, including storing carbon and protecting soil and water. Forests are also places with cultural, aesthetic and heritage values and provide recreational opportunities.

However, Australia’s forests are subject to many pressures, including extreme weather; drought; climate change; invasive weeds, pests and diseases; changed fire regimes; urban development; mining; agricultural management practices such as grazing; and the legacy of previous land management practices.

Distribution

Forests extend across Australia’s northern tropical regions, east coast subtropical regions, and warm and cool temperate zones in the south-east (Map 1). They are also found in Mediterranean climate zones in the south-east and south-west. In some regions, forests extend from the wetter coastal and sub-coastal areas into drier parts of the continent, and into sub-alpine and alpine zones. They grow on a range of soils, from ancient, fragile and infertile soils, to more recent, fertile soils of volcanic origin.

Queensland has the largest proportion of Australia’s total forest area (41 per cent), followed by New South Wales (18 per cent) (Table 1).

Australia’s National Forest Inventory

ABARES, through the National Forest Inventory (NFI), provides comprehensive information and reporting on Australia’s forests. The NFI is also the repository for a range of data about Australia’s forests compiled from state, territory and Australian government agencies.

How a forest is defined in Australia

A forest is an area of land dominated by trees that have a height of at least two metres and a crown cover of at least 20 per cent. Crown cover is the area of ground covered by tree canopies, ignoring any overlaps and gaps.

Large expanses of tropical Australia where trees are spread out in the landscape are forest, as are many of areas of multi-stemmed eucalypt mallee. What many people would typically think of as forests—stands of tall, closely spaced trees—comprise a relatively small part of the country’s total forest area.

Forest types

Australia’s forests are classified in the National Forest Inventory into three categories: ‘Native forest’, ‘Industrial plantations’ and ‘Other forest’.

Australia’s native forests are grouped into eight types:

  • Acacia
  • Callitris
  • Casuarina
  • Eucalypt
  • Mangrove
  • Melaleuca
  • Rainforest
  • Other native forest.

More than 80 per cent of Australia’s native forest area is dominated by Eucalypt forest and Acacia forest (Table 2).

Industrial plantations are plantations grown on a commercial scale for wood production. ‘Other forest’ comprises non-industrial plantations and planted forest of various types.

Forest structure

Australia’s native forests are divided into three classes based on their crown cover and three classes based on mature tree height. Crown cover is the area of ground covered by tree canopies, ignoring any overlaps and gaps.

The crown cover classes are:

  • woodland forest (20 to 50 per cent crown cover)
  • open forest (>50 to 80 per cent crown cover)
  • closed forest (>80 to 100 per cent crown cover).

The height classes are:

  • low (2 to 10 metres)
  • medium (>10 to 30 metres)
  • tall (>30 metres).

Distribution of Australia’s native forest by crown cover class is shown in Map 2. A total of 81.7 million hectares (67 per cent) of Australia’s native forest area is woodland forest (Table 3). Open forests comprise 33.9 million hectares (28 per cent) and closed forests comprise 3.8 million hectares (3 per cent).

The Eucalypt forest type is the largest component of both woodland forests (64.2 million hectares) and open forests (27.3 million hectares) (Table 3). The Rainforest forest type is the largest component of closed forests (2.6 million hectares).

Ownership

The ownership of a forest (or tenure), especially native forest, has a major bearing on its management. Six tenure categories are recognised nationally:

  • leasehold—Crown land that is privately managed

  • multiple-use public forest—publicly owned state forests and timber reserves

  • nature conservation reserve—land formally reserved for environmental, conservation and recreational purposes, including national parks, nature reserves, and state and territory recreational and conservation reserves

  • other Crown land—Crown land reserved for a variety of purposes, including utilities, scientific research, education, stock routes, mining, defence, and protection of water-supply catchments

  • private—land held under freehold title and privately owned

  • unresolved tenure—land for which data are insufficient to determine ownership status.

Distribution of Australia’s native forest by tenure is shown in Map 3. A total of 81.9 million hectares (67 per cent) of Australia’s native forest is privately managed on leasehold land and private land (Table 4), while 21.5 million hectares (18 per cent) are in formal nature conservation reserves.

Forest and forest products certification

Certification of forests and forest products assures Australian and international buyers that the forest products they purchase come from sustainably managed and legally harvested native forests and plantations. Several private, accredited bodies conduct forest and supply chain certification in Australia. They use standards developed under the Australian Forest Certification Scheme or the Forest Stewardship Council. A total of 10.5 million hectares of native forests and plantations are certified under these standards.

 

Australia’s State of the Forests Report series

Data on Australia’s forests are compiled in the National Forest Inventory. These data are used to complete the Australia’s State of the Forests Report series. A report is produced every five years through a collaboration between the Australian, state and territory governments, led by the Australian Bureau of Agricultural and Resource Economics and Sciences in the Department of Agriculture and Water Resources. This Australian forest profiles series is based on information in Australia’s State of the Forests Report 2013 and subsequent updates.

Criteria for sustainable forest management

Australia is a member of the Montreal Process, which provides a framework for describing, monitoring and assessing forests. The framework uses seven broad criteria to characterise the essential components of sustainable forest management:

  • conservation of biological diversity
  • maintenance of productive capacity of forest ecosystems
  • maintenance of ecosystem health and vitality
  • conservation and maintenance of soil and water resources
  • maintenance of forest contribution to global carbon cycles
  • maintenance and enhancement of long-term multiple socioeconomic benefits to meet the needs of societies
  • legal, institutional and economic framework for forest conservation and sustainable management.
Each criterion has a set of quantitative and qualitative indicators that are designed to measure progress and trends. A set of 44 indicators for use in Australia was adapted from the broader list to suit the specific characteristics of Australian forests, the products and environmental benefits they provide, and the people who depend on or use them. These criteria and indicators are used in the Australia’s State of the Forests Report series.
