Abstract

South Gippsland’s Corner Inlet and Nooramunga Marine and Coastal Parks are home to extensive beds of Broad-Leaf Seagrasses (Posidonia australis) . In recent years native sea urchins (Heliocidaris erythrogramma) have created extensive urchin barrens within these seagrass beds, reducing habitat for other species and making these areas vulnerable to erosion of sediments. This presentation will provide some details of the experimental approaches being undertaken by Parks Victoria to try and reduce the impact of these overabundant native grazers in this critically important habitat.

Biography

About the Association

The Australian Coastal Society (ACS) was initiated at the Coast to Coast Conference in Tasmania in 2004. The idea was floated as a means for those interested in coastal matters to communicate between conferences and where possible take resolutions of the conference to appropriate levels of government.

The idea was discussed further at the Coast to Coast Conference in Melbourne in 2006 and it was agreed that Bruce Thom develop a constitution of a company limited by guarantee that would operate on a national basis.

This plan was accomplished and in 2008 at the Coast to Coast Conference in Darwin the constitution was ratified and an Executive appointed. The company received charitable status in 2011.
