Forests represent the most important source of ecosystem services (ES) on a global level both for the production of goods and for the provision of services and externalities, nevertheless scientific research in the economic field is lacking. Currently the number of documents relating to ES is 16 673, of which only 1 379 concern the forestry sector. The aim of this study is to provide an overview of scientific research trends in the field of economic evaluation of forest ecosystem services (FES). To this end, an on-line bibliographic survey was carried out on the main scientific search engines, which made it possible to quantify the works and at the same time to detect the main evaluation methods used for the different FES. This survey allowed to collect 93 articles meeting the search criteria: the most active continents were Europe and Asia, whereas most of the articles focused on the joint evaluation of provisioning, regulation and cultural services, even if a good number of them only concerned cultural services. The most widely used valuation methodologies were the contingent valuation among the stated preference techniques and the market price among direct observation criteria.
