Seedlings of Ipomoea pes-caprae occurred on nine of the beaches studied (n=10) at Santa Catarina Island, (State of Santa Catarina) and in 21 monitored patches (n=30); it did not occur at the smallest beach. Seedling densities varied from 0 to 5.2 m2, and these differences are in part explained by viable seed bank densities. Seedling survival was low (0.6%) considering the 2823 plants monitored over three years. The main causes of death were wave erosion and burial. No seedlings survived at the beach zone (n=2684).
