Resource description:

The TESSA-toolkit focuses on a site-scale-level, such as a wetland, using information gathered locally. The toolkit can help assess climate regulation, flood protection, water provision, water quality improvement, harvested wild and cultivated goods and nature-based recreation. The toolkit is accessible to non-experts and practitioners on the ground, as it is a ‘user manual’ in a workbook structure. TESSA is relatively low cost to apply compared to many other methods. It delivers scientifically robust results, often based on field measurements, rather than scenarios. Methods are presented in a decision tree format to allow users to identify those most appropriate for their situation. Guidance on how to pull together data from individual ecosystem services into an ecosystem service overview is also provided.

Uses of this resource:

The toolkit includes methods for assessing global climate regulation (carbon storage, greenhouse gas fluxes), water-related services (flood protection, water provision, and water quality improvement), harvested wild goods (food, fibre, energy etc.), cultivated goods (crops, livestock, fish, timber etc.) and nature-based recreation.
