The maritime forest was classified into twenty types to use the presence and cover-degree of upper tree species (Table 1). 2. Twenty types of the maritime forest were classified into three classes by its habitat, beach forest, coasted escarpment and talus forest and delta forest. And the second one was divided into two groups, wind-beaten forest and wind-beaten scrub and the third one was divided into three groups, tidal flat forest, natural levee forest and inter levee swamp forest. 3. Among those maritime forest classes, the beach forest has been playing an important role for human living. Tree species which have been planted since old time to construct the wind break forest are native beach forest species, such as Pandanus odoratissimus, Hibiscus tiliaceus, Cerbera manghas, Calophyllum inophyllum, and introduced one which suitable for beach forest, such as, Casuarina equisetifolia and Casuarina glauca. 4.
