We will present recent findings arising from the Tropical managed Forests Observatory. Results from the first regional analysis of above-ground carbon stocks dynamics post-logging in Amazon managed forests will be presented. We found that the percentage of initial carbon lost during logging was the main driver of post-logging dynamic, enabling on his own to accurately predict time of recovery wherever in the Amazon Basin.Moving from forest stand to tree responses, we show how logging, by releasing competition for light, may affect trees morphology. We found a significant reduction of both total and bole heights proportional to logging intensity in a tropical logged forest in French Guiana. This resulted in a 10-13% reduction of tree biomass and timber volume. These results will be discussed in terms of future management and provision of ecosystem services in tropical production forests. (Texte intégral)
