Abstract
In the Anthropocene, ecosystems are changing along with their capacity to support human well‐being. Monitoring ecosystem services (ESs) is required to assess the changing state of human–nature interactions. To standardize the monitoring of multiple facets of ESs, the Group on Earth Observations Biodiversity Observation Network (GEO BON) recently proposed the essential ecosystem service variables (EESVs), which are organized into six classes: Ecological Supply , Use , Demand , Anthropogenic Contribution , Instrumental Value , and Relational Value . We apply the EESV framework to three case studies in British Columbia, Canada, each targeting a single ES. Using trend and intervention analysis, we show how EESVs are changing and affected by policy. We discuss key challenges and solutions while providing guidance on how to quantify EESVs. Finally, we demonstrate the potential of EESVs to harmonize metrics across conceptual frameworks, monitor ES change, and provide decision support to assess progress under various international policy conventions.
