The Forest Research Centre (CEF) is a research unit devoted to the integrated research of forestry and related ecosystems, forestry products and forest-related services, established in 1976, within the National Research Network and incorporated in ISA. Our research is organized into four Research Groups: ForEco: Forest ecology ForProtect: Sustainable management of biotic resources, ecosystem quality and services ForChange: Forest ecosystem management under global change ForTec: Forest products and biorefineries CEF develops research, post-graduate education, and outreach activities on issues dealing with forests, agro-forestry systems semi-natural areas, and forest-based industrial chains. CEF shares the EU Forest2020 da UE vision of forests and semi-natural areas as vital, productive and multifunctional ecosystems, contributing to sustainable development and human well-being, in a healthy environment. CEF is committed to an international perspective on research issues and fosters a diverse academic community. Most of our experimental research is located in Portugal, but it extends to the Mediterranean region and to tropical and sub-tropical regions and encompasses global approaches. The Forest Research Center was classified as EXCELLENT by the Fundação para a Ciência e Tecnologia, in the Evaluation that took place in 2019.
