The Effect of Increased Sediment Accretion on the Survival and Growth ofRhizophora apiculataSeedlings

Abstract The effects of experimental sediment accretion on the survival and growth ofRhizophora apiculataseedlings planted on an expanding mud flat in Pak Phanang Bay (south-east Thailand) were assessed. Seedling mortality rates increased linearly (R2=0·87,F=75·9,P 4 cm) sediment accretion and, therefore, afforestation programmes based on this species are unlikely to be successful in such areas.
