76. Cranbourne - Cranbourne Sand Type Locality

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
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. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Access:

Botanic Drive.

Ownership:

Crown Land.

Geology/Geomorphology:

The site includes low ridges and swampy depressions with a heath or scrub and woodland vegetation. The ridges of fine grained, yellow stained quartz sands. The composition, bedding, and configuration of the deposits indicates they originated as dunes (Jenkin, 1962), and are part of an extensive belt of aeolian sands trending north-west south-east between Tooradin and Cranbourne. They have been referred to stratigraphically as the Cranbourne Sand (Jenkin, 1962).

Significance:

State. This site contains one of the most extensive areas of relatively undisturbed Cranbourne Sand topography in the mainland section of the Westernport Bay catchment. As well as being distinctive examples of aeolian terrain, the Cranbourne Sand also played a role in the development of the Koo-Wee-Rup Swamp.


Management:

Class 1. No activities that would disturb the topography or drainage of the site should be permitted. Such activities include quarrying, subdivision, clearing and further road construction.
