Keora (Sonneratia apetala Buch.-Ham) is the principal species in the coastal plantations of Bangladesh. Rotation ages were estimated for the species considering four important criteria. It was observed that the rotation ages vary from 6 to 21 years for site indices 18, 15, 12, 9 and 6 meters at a reference age of 12 years. Considering the different factors of raising the coastal plantations, a rotation age of 12 years for site indices 15 and 18 meters dominant height and 15 years for site indices of 6, 9 and 12 meters dominant height at the same reference age may be prescribed for keora in the coastal plantations of Bangladesh.
