The objective of the COST E4 Action was to create a European network of forest reserves in order to collect ongoing research and unify research methodologies and have access to a central databank for the exchange of research results. The output of the COST E4 action was a publication of country reports with data and definitions on forest protection and a report on research in natural forests and reserves, a review of the models and methods for describing the structure of natural forests and reserves, a review of the models and methods for describing the structure of natural forests and a data bank on forest reserves, organisations, publications, research and the main results with free access for the participants.
Country reports for the COST Action E4: Forest Reserves Research Network have been published in EFI Proceedings 16.
