10. Tarra River Estuary

This information has been developed from the publications:

  • Sites of Geological and Geomorphological Significance in Central Gippsland (1981) by Neville Rosengren, M.S McRae-Williams and S.M Kraemers,
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay and in the Catchment of Westernport Bay (1984, 88) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the South Gippsland Marine and Coastal Parks (1989) by Neville Rosengren.
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 (external link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Avicennia marina and Phragmites australis - Tarra River estuary.

Access:

Old Scale Road, Robertsons Beach Road.

Ownership:

Crown Land and private land.

Geology/Geomorphology:

The Tarra River estuary displays the same contrast in meander form described for the Albert River estuary. Of particular interest is the distribution of
Avicennia marina and Phragmites australis along the estuarine channel. Avicennia extends over three kilometres upstream from the north of the estuary while Phragmites is found along the channel banks growing amongst and in front of Avicennia in areas near the mouth of where the tidal range is in excess of 1.5 metres.

Significance:

Regional. Vegetation and sediment dynamics of this estuary have not been studied in detail. The relationship between vegetation distribution, tidal inundation and salinity levels in the estuary are of particular interest.

Management:

Site 8220 – 9
