A provenance trial with 23 provenances of Acacia mangium was carried out at Keochia Silvicultural Research Station, Chittagong during the year 1983. The primary results showed that the provenances of West of Morehead and Oriomo River of Papua New Guinea,  Abergowrie  SF and Hawkins creek RD. Parish of Leach Queensland, Australia may be suitable for afforestation programme under the condition of Chittagong forest zone. The experiment needs to keep under close observation before making any firm conclusion.
