Landscape Health In Australia
A rapid assessment of the relative condition of Australia's bioregions and subregions

Assessing landscape health
Condition and trend attributes used to assess the subregional landscapes were selected to be independent variables, in order to allow exploration of a wide range of surrogates for landscape and biodiversity status and health. Most of these attributes are related. Increasing fragmentation of native vegetation and intensification of land use are primary drivers of biodiversity decline. They are also associated with changes in rainfall infiltration and run-off, and consequent changes in landscape hydrology, including changed river flows and dryland salinity.
The current health of a particular subregion is best assessed by an analysis of its condition and trend attribute values. However, an assessment of the relative health of the subregions will be more easily made using a synthesis of reported attribute values.
