Annual marine biota monitoring surveys at the Twofold Bay Multi-Purpose Wharf in Eden NSW were required to support the Royal Australian Navy activities. Construction and operational approvals for the facility require annual monitoring to demonstrate environmental controls for the facility. Naval vessel activities and wharf activities have potential to impact upon sensitive environmental receptors within Twofold Bay. This includes naval vessel transit within Australian and International waters which has potential of introducing or trans-locating marine pests to Twofold Bay, principally as a result of bio fouling introductions.
Eco balance was engaged to assist with this project’s field studies which included:
Based on the findings there appears to be no significant changes in the overall condition or status of the marine biota of Twofold Bay that can be attributed to the ongoing activities associated with the wharf and jetty. Based on the findings and conclusions of this study the following recommendations were made:
