The TESSA toolkit provides practical guidance for measuring ecosystem services at the site scale.It effectively communicates the results to aid decision-making on a local level,which is an area existing tools have had limited applicability.TESSA provides scientifically robust information and a simple gross assessment of ecosystem services (e.g.climate regulating,coastal and waters services; nature-based tourism,harvested wild and cultivated goods). TESSA has been tested in over 10 case study sites in different parts of the world.The toolkit helps users to identify which services to assess,what data are needed to measure them,which methods or sources might be used in different contexts and how the results can be communicated to stakeholders.
