Participating Institutions
1 - IMAR-CIC (Departamento de Botânica) 2 - Escola Superior Agrária de Coimbra 3 - Instituto da Conservação da Natureza

This project aims to continue and further develop the studies started in 2002, INVADER I "Evaluation of the recover potential of ecosystems invaded by Acacia and methodologies to control invasion", on the recovery of a dune ecosystem invaded by Acacia longifolia and including original tasks suggested after our results. For this project, we have selected an invaded coastal area with high conservation value - Natural Reserve of S. Jacinto Dunes (NRSJD) where the invasion by A. longifolia is spread extensively in the area threatening plant diversity and promoting functional changes at the soil level. This project will contribute to the resolution of invasion problems by A. longifolia, by regarding issues related to specific needs for the management of A. longifolia invasion and to improve scientific knowledge about invasion process and to promote public awareness.
