Abstract
Prior to 1960, Can Gio mangrove forest in Vietnam covered area of 40,000ha; the canopy was dense, with trees over 20m tall. During the 1970’s, the forest suffered almost complete destruction. Can Gio mangrove reforestation work has continued consistently from 1968 to the present day. After 30 years of rehabilitation and development by the hard efforts of Ho Chi Minh City government and people, the forest become the largest replaced mangrove areas in Vietnam. This significant fact led to its recognition by the MAB/UNESCO Committee on January 21, 2000, as a Mangrove Biosphere Reserve.
