The provision and remuneration of forest ecosystem services (ES), such as the regulation of water quality, biodiversity, and soil quality, is one of the central themes of the EU Strategy for Forests 2030, thus resulting in a justified perception of the importance of public policies associated with it (forest, biodiversity conservation, spatial planning) that can stimulate sustainable forest management and its certification. The project aims to develop and test methodologies for the evaluation and valuation of forest ES adapted to Portugal and integrated into international standards.
