This project aimed to evaluate the recovery potential of coastal systems invaded by Acacia, the diversity and dynamics of vegetation and soil, integrating biological and mechanical control. Biological control, never before tested for the control of Acacia in Portugal, has started to be evaluated in quarantine conditions. It was also aimed to elaborate a coherent action plan for the reduction of Acacia invaded areas and the recovery of invaded systems, contributing for a better management and protection of coastal areas.
