11.1 MERI for the Manning River, Estuary and Catchment

11.1 MERI for the Manning River, Estuary and Catchment

MidCoast Council will implement a broadscale environmental monitoring, evaluation, reporting and improvement (MERI) program to support the management objectives of the ECMP.

The MERI Program will provide a high-level assessment of environmental quality to ensure the values in Section 2 are maintained across the Manning River Estuary and Catchment. Implementing the MERI Program will assist Council and our stakeholders to establish a baseline of data characterising water quality including ecological health. Continued long-term monitoring will enable us to detect changes (positive or negative) in water quality over time. Analysing the data will aid decision-making and adaptive management, helping us to improve the program and achieve our objectives. The MERI Program constitutes the science program defined in the CMP Program Logic Model (see Section 3.4).

11.1.1 Principles

The MERI Plan adopts the following Principles:

• Uses SMART Objectives – Specific, Measurable, Achievable, Realistic, Timebound.

• Relies on an agreed program logic – robust methodology to ensure outcomes can be effectively measured.

• Uses Best Practice - current best practice and scientific knowledge and multiple (environmental indicator) lines of evidence.

• Adopts a risk-based approach – assists MidCoast Council to prioritise monitoring of ecological responses and stressors that pose the highest risk to ecological health.

• Emphasises collaboration – builds on existing programs to improve efficiency and reduce duplication in effort.

• Transparent reporting – offers open access to information.

• Adaptive Management – adopts a systematic approach to improving natural resource management by learning from management outcomes and making changes to improve the ecological response and reduce stressors.

• Values cultural knowledge – recognises the importance of cultural knowledge holders in increasing understanding of the condition and health of the Manning River

Estuary and Catchment and the influence environmental change may have on physical and non-physical elements of cultural heritage.

• Values local knowledge – recognises the value of local knowledge in understanding and interpreting scientific results about the heath and condition of the Manning River

Estuary and Catchment.

• Values citizen science – recognises the role of citizen science programs in filling knowledge gaps and increasing understanding of the condition and health of the

Manning River Estuary and Catchment.

11.1.2 Approach

Council’s approach to development of the MERI Plan for the Manning River Estuary and Catchment included the following steps:

• Examining current understanding - to inform decisions at subsequent steps,

MidCoast Council developed conceptual models of how the Manning River Estuary and Catchment waterway systems work, the issues they face and how to manage them.

• Defining community values and management objectives - community values and more specific management goals (including level of protection) were defined for the

Manning River Estuary and Catchment at stakeholder involvement workshops (refer to Section 2).

• Defining relevant indicators - indicators were selected for relevant pressures identified for the system, the associated stressors and the anticipated ecosystem receptors.

• Determining water quality guideline values - MidCoast Council determined the water quality guideline values for each of the relevant indicators required to provide the desired level of protection to meet the management goals of the Manning River

Estuary and Catchment.

• Implement management strategy - MidCoast Council developed this MERI Plan to document its approach to achieving the water quality objectives and the environmental monitoring programs for implementation.

This approach was based on the principles and guidelines of the National Water Quality Management Strategy (NWQMS 2018), with regard to the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZG 2018). The focus of the approach is on maintaining existing water quality, identifying where management and/or remediation actions may be required and to measure the effectiveness of these actions.

The water quality management framework adopted in the MERI Program is shown in Figure 38.

MERI programs to be implemented for the Manning River Estuary and Catchment are summarised in Table 5.

11.1.3 Evaluation and Continual Improvement

The MERI Program will be continuously reviewed to:

• Assess if water quality objectives are met - Use measurements from monitoring of each relevant indicator to assess whether water quality meets the water quality objectives.

• Consider additional indicators or refine water quality objectives - Assess the need to revise or add to the lines of evidence or indicators and the water quality guideline values.

• Consider alternative management strategies - Evaluate the effectiveness of current management strategies to address the identified water quality issues and recommend possible improvements. Improved or alternative management strategies are formulated, assessed and prioritised.

• Assess if water quality objectives are achievable - Use information gained to assess whether the water quality objectives are achievable.

The project team will use adaptive management to improve on-ground management decisions in order to meet the water quality objectives of the Manning River ECMP. Adaptive management allows Council and stakeholders to adjust our approach in response to current climatic conditions, new information and local knowledge.

11.1.4 Reporting

MidCoast Council is committed to open access to information. The results of implementing the MERI Plan for the Manning River Estuary and Catchment will be reported to the ECMP Reference Group and community through established engagements methods (e.g. Water Quality Report Card, Creek to Coast newsletters).
