Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports.

Site Description

On the steep slopes of Flagstaff Hill, weathered Palaeozoic sediments have developed a clay-rich soil. Clearing and intensive grazing (stock and rabbits) have contributed to severe tunnel and gully erosion being maintained, with long parallel gullies and downslope sequences of tunnels and tunnel mouth fans evident. Improved land management and physical reclamation has reclaimed much of the deteriorating land surfaces although some smaller gullies persist and tunnel development is still active.

Significance

Regional. The site demonstrates the fragile equilibrium of slopes developed on the Ordovician shales and mudstones.

Management

Class 3. Continued appropriate stocking ratios, revegetation and rabbit control are required at the site.
