<strong>1.10</strong>.9.1 Australian Environmental Condition Assessment Framework<br />
The National L<strong>and</strong> <strong>and</strong> Water Resources Audit <strong>of</strong> the Department <strong>of</strong> Water is develop<strong>in</strong>g<br />
an assessment <strong>of</strong> the condition <strong>of</strong> Australian estuaries through an <strong>estuar<strong>in</strong>e</strong> condition statement<br />
that summarizes all available <strong>in</strong>formation <strong>and</strong> a report card that identifies pressures,<br />
vulnerabilities <strong>and</strong> management objectives. A national condition assessment framework provides<br />
a practical <strong>and</strong> logical structure for regional <strong>and</strong> national report<strong>in</strong>g, direct<strong>in</strong>g research, enhanc<strong>in</strong>g<br />
communication, facilitat<strong>in</strong>g coord<strong>in</strong>ation between jurisdictions <strong>and</strong> guid<strong>in</strong>g identification <strong>of</strong><br />
<strong>in</strong>dicators (Arundel <strong>and</strong> Mount 2007). The condition <strong>classifications</strong> <strong>of</strong> 971 estuaries (i.e., nearprist<strong>in</strong>e,<br />
largely unmodified, modified <strong>and</strong> extensively modified) relied ma<strong>in</strong>ly on qualitative<br />
<strong>in</strong>formation <strong>and</strong> expert op<strong>in</strong>ion on a range <strong>of</strong> criteria (Heap et al. 2001). Subsequent studies have<br />
demonstrated systematic changes <strong>in</strong> geomorphic <strong>in</strong>dicators with dim<strong>in</strong>ish<strong>in</strong>g condition status (i.e.<br />
from near-prist<strong>in</strong>e, through modified to severely modified) po<strong>in</strong>t<strong>in</strong>g to changes <strong>in</strong> the surface<br />
area <strong>of</strong> sediment facies (habitats) between modified <strong>and</strong> prist<strong>in</strong>e estuaries (Heap et al., 2004) <strong>and</strong><br />
