2. Outline • What is CLAM? • History of CLAM development • CLAM uses and development approach • Custodianship and accreditation

3. What is CLAM? • The Coastal Lake Assessment and Management (CLAM) tool was developed to allow stakeholders, in particular Local Government Planners, to assess the social, economic and environmental trade-offs associated with development, remediation and use options for coastal lakes and estuaries • The tool consists of a software package which relies on a Bayesian Network approach to model the lake system • Uses a process that relies heavily on stakeholder and expert feedback and open documentation of underlying assumptions and data sources • CLAM is not only a software system but an approach to model development and communication

4. CLAM Tools • Use methods developed in DNR funded pilot study which aimed to assess the sustainability of eight coastal lakes on NSW coast (Sustainability Assessments of NSW Coastal Lakes: 2004 to 2005) • Features of the CLAM tool • Simple representation of complex systems, including social, economic, ecological and physical processes and their connection • Able to incorporate quantitative and qualitative data (e.g. observed data, model simulation, expert knowledge) • Extensive internal documentation of model and data assumptions and quality • Implicitly recognises the level of uncertainty in results and hence confidence in the outputs by using conditional probabilities • Easy to update as new information becomes available • CLAM does not make decisions for you but can be used to aid in decision making by clarifying the trade-offs involved

6. 2005: iCAM sub-contracted to complete parts of the HSC funded ICM Development project 2005: iCAM contracted to develop prototype CLAM tools for Smiths and Wallis Lakes 2006: Economic component of Back Lake and Merimbula Lake CLAMs revised (DEC, Gillespie Economics) 2006: Training workshops on application and tailoring of the Coastal Lake Assessment and Management (CLAM) tools 2006+: CLAM project developing applications for 16 coastal lakes in northern NSW (NRCMA) History of CLAM 2002: Healthy Rivers Commission Independent Inquiry into Coastal Lakes; Cabinet Office releases a Statement of Intent for implementation of the Coastal Lakes Strategy 2004: As part of the CCA program, iCAM contracted by DNR to develop sustainability assessment methodologies for 8 NSW coastal lakes

7. What can CLAM be used for? • To understand the social, economic and environmental trade-offs associated with management of coastal lakes • To facilitate and promote discussion between planners and the wider community regarding the management of an estuarine system • As an educational and learning process for communities and government bodies • To support development of Estuary Management Plans

8. CLAM development process • The extent of model review in stages 7 and 8 depends on the available resources (time, money and/or information) and the level of response from stakeholders • Users should be aware of the aims, strengths and limitations of each CLAM tool when using its output to inform a decision

9. How should CLAM be used? • CLAM aims to represent the best available knowledge on impacts in an integrated way • Knowledge of many key variables is frequently very poor • CLAM approach to is include these in the framework and use the best available data • Reflect and document the poor quality information to provide direction on where further monitoring or studies should be carried out • Provide a framework for this information to be included in the assessment once it becomes available • CLAM results should always be actively questioned and should only be accepted after close consideration • Use CLAM as the basis of a communication process • Do people agree or disagree with the results? • Why? • Can they reach consensus on the nature of the impacts? Why/why not? • Do these impacts matter and is there any action that could be taken to reduce the impacts

10. CLAM Custodianship • Anyone can change model data: • This is the case with any model (not just CLAM) • How can users ensure the model can change and grow while maintaining the quality assurance of the product? • Who will be allowed to have copies of the model and under what conditions can they be used? • Who maintains the model and ensures proper documentation procedures are followed? • Our preferred approach: • CLAM management group to critically review and manage changes into the future (data, nodes and scenarios) • Central management & key contact person (local council, DNR, CMA or consultant) to maintain the ‘accepted’ CLAM

11. CLAM Roll-out • CLAM is moving from a development phase to an implementation phase • Creating a group of people outside ANU who can develop, update and maintain CLAM tools to break the reliance on ANU researchers for these tasks • Ensuring a modest income stream to enable maintenance and development of the software into the future • Quality assurance of CLAM products

12. Roll-out approach • CLAM user training • Broad based training sessions for communities on the use of individual CLAM tools • Aims to teach people the appropriate uses of the CLAM tool and provide them with enough training to use CLAM for making decisions • Focus has been on local council staff and Councillors, Estuary Management Committees and State Government staff • CLAM developer training and accreditation • Narrow and intense training in CLAM development and methods • Focus has been on consultants to provide Councils etc with a locally based and accessible group of CLAM developers • Accreditation process to ensure maintained quality of the CLAM approach and products
