The Tropical managed Forest Observatory (TmFO) aims to assess the impact of logging on forest dynamics, carbon storage and tree species composition at regional level in the Amazon basin, Congo basin and southeast Asia. To do this, TmFO is carrying out a meta-analysis based on data provided by existing permanent sample plot networks set up by the research institutions involved inÍTmFO. The permanent sample plot networks ofÍ TmFO gather 29 experimental sites, 372 plots representing an area of more than 900 ha. The results are expected to provide key insights into a better understanding of forest responses to logging Íat regional scale. This will allow TmFOÍto make new recommendations towards more sustainable and profitable forest management.
