In this work the survival and performance of transplanted mangrove trees in Saco da Fazenda (Itajaí, SC), were monitored from March to December 2001. Three hundred and fifty transplanted trees were tagged and the trunk basal diameter and tree height were measured. The health of trunk, leaves and roots were also observed. Maximum tree heights were about 3.5m and larger trunk diameters were about 4.0-4.5cm. Mortality was higher to trees higher than 1.0m. Trees higher than 3.0m did not survive to replenishment. Survival of high trees occurred only in areas protected from hydrodynamics, were stress by sand mobility were lower.
