Introductory Notes This Ecological Character Description (ECD Publication) has been prepared in accordance with the National Framework and Guidance for Describing the Ecological Character of Australia’s Ramsar Wetlands (National Framework) (Department of the Environment, Water, Heritage and the Arts, 2008).
The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) prohibits actions that are likely to have a significant impact on the ecological character of a Ramsar wetland unless the Commonwealth Environment Minister has approved the taking of the action, or some other provision in the EPBC Act allows the action to be taken. The information in this ECD Publication does not indicate any commitment to a particular course of action, policy position or decision. Further, it does not provide assessment of any particular action within the meaning of the Environment Protection and Biodiversity Conservation Act 1999 (Cth), nor replace the role of the Minister or his delegate in making an informed decision to approve an action.
This ECD Publication is provided without prejudice to any final decision by the Administrative Authority for Ramsar in Australia on change in ecological character in accordance with the requirements of Article 3.2 of the Ramsar Convention.
Disclaimer While reasonable efforts have been made to ensure the contents of this ECD are correct, the Commonwealth of Australia as represented by the Department of Sustainability, Environment, Water, Population and Communities does not guarantee and accepts no legal liability whatsoever arising from or connected to the currency, accuracy, completeness, reliability or suitability of the information in this ECD.
Note: There may be differences in the type of information contained in this ECD publication, to those of other Ramsar wetlands.

The assistance of a number of people, from both government agencies and from the local community at Swansea and Coles Bay is acknowledged. The project advisory committee – Prof Alastair Richardson, Ian Houshold, Danielle Hardie, Imogen Birley, Stewart Blackhall, Christine Crawford, and Kayleen Allen – provided valuable input into the structure and review of the Ecological Character Description, as did reviewers Jennifer Hale, Rhonda Butcher and Lance Lloyd. Data was made available from Department of Primary Industries Parks, Water and Environment, Tasmanian Aquaculture and Fisheries Institute, Bureau of Meteorology. Community members, farmers, marine farmers, bird and fish enthusiasts gave freely of their time to offer information and some important historical insights into the nature of Moulting Lagoon, both prior to listing and since
