The aim of this study is to clarify the sur vival and growth performances of six native mangrove species (Avicennia officinalis, Avicennia marina, Br uguiera sexangula, Heritiera fomes, Rhizophora apiculata and Sonneratia apetala) that were replanted on abandoned paddy fields in the

The majority of the population in Vietnam lives in the coastal areas, where they, economically poor farmers and fishermen, suffered from the serious damage caused by mangrove destruction. The target of the project is restoration of mangrove forests to their condition before the Vietnam War started. About 20Q000 ha should be planted by supporting the reforestation activities of Vietnamese villagers. As the result of some three yeari preparation activities in research, reforestation support, etc. in Vietnarn" we concluded that the restoration is possible. Labour for planting will require 2-4 million people . day. This is the work that 500 organizations, each of 400 workerswould be able to execute in 10-20 days.Women's Unions and secondary schools, which are spread all over Vietnam, will be expecied to cooperate in this project. Project term is scheduled for L0 years and the cost estimatd twelve hundred million yen.Mangrove forests in the tropics have been decreased and degraded year by year. We expect that this project will be a "model" for mangrove restoration on a global level.
