This chapter examines the process and value of monitoring and evaluation for green infrastructure, and how logic models can be used to get the most from the development and implementation of a monitoring and evaluation strategy. To this end, the second section introduces the chapter. Definitions of, and basic principles for, conducting monitoring and evaluation are provided, and a scenario is described that is used within the chapter for examples of how to monitor and evaluate green infrastructure. The next section describes logic models and their use. Then there is a step-by-step look at the do–review approach to monitoring and evaluation, followed by worked examples: seven logic models for the delivery of ecosystem services by one type of green infrastructure – community woodland. The final section concludes and presents a challenge for monitoring and evaluation to be implemented throughout the lifecycle of green infrastructure planning, delivery and management, and to promote the delivery of ecosystem services by green infrastructure for the benefit of society.
