Australia’s forests and forestry glossary
The non-biological components of the environment (e.g. climate).
Above-ground living biomass
Australia’s largest genus of flowering plants, commonly referred to as wattles.
Increasing levels of acidity that can damage soil and vegetation.
Advanced Very High Resolution Radiometer (AVHRR)
A remote-sensing technology carried on two polar-orbiting satellites each with a multi-spectral scanning radiometer providing imaging information of the Earth’s entire surface at a resolution of 1.1 kilometre. AVHRR data provide information on vegetation cover and vegetation change (e.g. after fire).
A group of trees of a similar age, such as a cohort of native forest trees regenerating after a disturbance event, or a set of plantations established in a given time-period.
1. Establishment or management of trees or forest stands (either plantation or native forest) on private agricultural land, generally for commercial benefit including wood production but also for farm management, environmental or aesthetic reasons.
2. A land-use system that integrates trees with agricultural crops or animals in the same land management unit.
Also known as farm forestry.
A genus of trees closely related to the genus Casuarina, both of which are commonly referred to as she-oaks.
See Casuarina forest.
Growth habit of a shoot whereby growth and development of lateral buds are suppressed.
A collection of living trees established at a single site, at least partly for observation and scientific study. Plural: arboreta.
Logs produced (arising) as a result of the harvest of logs of other species or of other grades, but that do not meet the size or quality specifications for those other species or grades.
A measure of stand density that sums the cross-sectional area of trees at breast height (1.3 metres above ground) in a given area of forest.
Below-ground living biomass
An energy source made from organisms and their products (biomass) such as wood and plant matter, algae, or animal fats.
Relating to the study of the geographic distribution of living things.
1. Material of biological origin (plant or animal).
2. Living and dead organic material located above-ground and below-ground, for example trees, grasses, litter, roots and soil organic matter, often determined for the purposes of carbon accounting.
A large, regional ecological unit, usually defined by some dominant vegetation pattern.
A large, geographically distinct area that has a common climate, geology, landform, and vegetation and animal communities.
The biological components of the environment (e.g. plants, animals and other organisms).
Referring to biota.
Log taken from a tree trunk between the ground and the crown break (the height of the first major branch).
See Crown (tree).
Volume of a bole log.
Fire started naturally (such as by lightning), accidentally, or deliberately (such as by arson), but not in accordance with planned fire management prescriptions. Also called unplanned fire or wildfire.
A general term in Australia for natural vegetation, covering any kind of habitat from open, shrubby country with scattered trees, to tall, closed forests.
A genus of gymnosperm trees. Most species of Callitris occur in Australia, and are commonly referred to as cypress pines.
See Crown cover.
CAR reserve system
Comprehensive, adequate and representative reserve system: a forest reserve system that includes the full range of vegetation communities (‘comprehensive’), with a level of reservation sufficiently large to maintain species diversity as well as community interaction and evolution (‘adequate’), and conserving the diversity (including genetic diversity) within each vegetation community (‘representative’). The CAR reserve system comprises dedicated formal reserves, informal reserves, and areas where forest values are protected by management prescriptions, as well as areas protected on private land.
Determination of the amount of carbon stored in an ecosystem and changes in this amount.
A tradable certificate, permit or legal instrument, deriving from a verified reduction of one unit (one tonne) of carbon dioxide emissions (or equivalent), and tradable to offset one unit (one tonne) of carbon dioxide emissions (or equivalent).
Carbon dioxide equivalent
Unit for amount of greenhouse gas, as the amount of carbon dioxide (CO2) that has the same radiative effect in the atmosphere. Abbreviated as CO2-equivalent or CO2-e.
See Greenhouse gas.
Removal of carbon from the atmosphere and its storage in vegetation, soils or elsewhere.
A carbon reservoir or pool that has the capacity to accumulate carbon.
A carbon reservoir or pool that has the capacity to release carbon.
Quantity of carbon in a carbon reservoir or pool. For example, the quantity of carbon stored in forests and wood products.
