Ecological community

An assemblage of native species that inhabits a particular area in nature. (abridged Environment Protection and Biodiversity Conservation Act 1999 definition)

Ecologically Sustainable Development

The Ecological Sustainable Development Working Group on Forest Use has specified three requirements for sustainable forest use: maintaining the ecological processes within forests (the formation of soil, energy flows and the carbon, nutrient and water cycles); maintaining the biological diversity of forests; and optimising the benefits to the community from all uses of forests within ecological constraints. (National Forest Policy Statement) (There is no common definition in the literature for this term).

Ecologically Sustainable Forest Management (ESFM)

ESFM is about managing forests to ensure they meet our present needs without affecting the options they can provide for future generations and, at the same time, maintain and protect other forest values

Ecological Vegetation Class (EVC)

An EVC is a grouping of vegetation communities based on floristic, structural and ecological features.

Ecosystem

A dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit. (Environment Protection and Biodiversity Conservation Act 1999 definition)

Endangered species and communities

Species in danger of extinction and whose survival is unlikely if the causal factors continue operating. Included are species whose numbers have been reduced to a critical level or whose habitats have been so drastically reduced that the species are deemed to be in danger of extinction. Also included are species that are possibly already extinct but have definitely been seen in the wild in the past fifty years and have not been subject to recent thorough searching. (National Forest Policy Statement)

Endangered Forest Ecosystem

An endangered forest ecosystem is defined as one which is likely to become extinct in nature unless the circumstances and factors threatening its extent, survival or evolutionary development cease to operate; as determined by the application of the criteria outlined in section 6.1.
