Intertidal and Sandy Beach Ecology

Both mechanical and manual beach cleaning are carried out in Mosman. As wrack (seaweed) is vital to maintaining beach ecology some beaches are cleaned manually to minimise disturbance to wrack. Chinaman’s Beach has been cleaned manually since 2004.

The ecology of Chinamans Beach has benefited from being left in its natural state following the commencement of manual beach cleaning, and beach users are not unduly impacted upon by the presence of wrack on the beach.

A Photo-Point Monitoring Program was undertaken at Chinamans Beach during spring/summer 2004 and autumn/winter 2005, to gain an understanding of wrack on Chinamans Beach.

Wrack was been identified as influencing the distribution, abundance and diversity of organisms by providing habitat, shelter and a source of food. Over the course of the monitoring program Chinamans Beach was transformed from a historically ‘bare beach’ into a beach teeming with an abundance and diversity of shells, sponges, shark eggs and other marine organisms, insects, crabs and birdlife.

Intertidal Monitoring

In 2015, Mosman Council received a grant supported by the Sydney Coastal Councils Group and funded by the Australian Government as part of the Sydney’s Salty Communities grant to connect biodiverse foreshores of Mosman. Part of this grant included the development of an intertidal monitoring plan for Mosman intertidal foreshore zones. The monitoring plan was developed by external consultants, with the aim of Council Environmental staff to undertake the survey twice a year (Autumn and Spring). Data collected in 2016 will be the baseline data for future years.
