Regional Ecosystems

Regional ecosystems (REs) are communities of vegetation that are consistently associated with a particular combination of geology, land form and soil in a bioregion. Each regional ecosystem has been assigned a conservation status which is based on its current remnant extent (how much of it remains) in a bioregion.

Regional ecosystems are declared in the Vegetation Management Regulation 2000 and are classified as:

Endangered if:

• the area of remnant vegetation for the regional ecosystem is less than 10% of the pre-clearing extent of the regional ecosystem; or
• the area of remnant vegetation for the regional ecosystem is 10% to 30% of the pre-clearing extent of the regional ecosystem and less than 10 000 hectares.

Of concern if:

• the area of remnant vegetation for the regional ecosystem is 10% to 30% of the pre-clearing extent of the regional ecosystem; or
• the area of remnant vegetation for the regional ecosystem is more than 30% of the pre-clearing extent of the regional ecosystem and less than 10 000ha.

Least concern if:

• the area of remnant vegetation for the regional ecosystem is more than 30% of the pre-clearing extent of the regional ecosystem and more than 10 000ha.
