The goal of the workshop is to draft the implementation plans for a coordinated observing system of EOVs and EBVs associated to Seagrass and Mangrove ecosystems to support biodiversity and health status assessments of these fundamental coastal habitats. The workshop will bring together a multidisciplinary community of scientists and stakeholders including from the above-mentioned monitoring programs to identify elements required for a multi-year implementation of an observing and analyses system for this EOV/EBV alignment. The group will identify level of maturity of measurements in terms of requirements, coordination of observations, address gaps in observation and user needs, and advance data management and information products. These will build on the assessments done by the GOOS BioEco Panel, the Biological Integration and Observation Task Team (BIO-TT), and the Marine Biodiversity Observation Network(MBON).
