The GUIAMAFLOR project includes French (Guyana and Montpellier) and Brazilian (Manaus and Macapá) research partners. The fieldwork is located in four sustainable systems in three Amazonian regions (French Guyana, Amapá and Amazonas) aiming to understand how environmental factors influence the forest dynamic after logging in multiple intensity levels. With the project’s results it will be possible to make a synthesis of the knowledge about forests’ functioning after logging to improve forest management plans, contributing inclusively to a reflection about the future of forest management to provide and preserve goods and environmental services in a rapidly changing Amazonian context.
