Develop criteria for prioritising monitoring so it is cost-effective.
Develop indicators to assess the means and ends of the plan, and how effective implementation of policies and methods was/is.
Make the most of the data you already collect and supplementary information from different agencies. Consider links between:
other policy objectives within council such as non-Resource Management Act requirements including pest management, reserve, land transport strategies, Long Term Plans and so on
territorial local authorities, regional councils and others
state of environment, consents, complaints, compliance monitoring
different environmental media and other agencies' work.
Combine your council databases to include all useful existing information (state of environment, compliance and complaints monitoring) and feedback to policy and other plan provisions.
