The preliminary study on some natural plant communities of the sandbars along eastern coast of peninsular Thailand

Surveys on the natural plant communities on the sandbars along the eastern coast of the peninsular Thailand in three provinces, Nakhon Si Thammarat, Songkhla and Narathiwat, have been carried out. Most of the natural vegetation on these sandbars had been become extinct, except for some remnants, left as separated spots. Four sites of those remnants were explored in this preliminary study. The plant species composition investigation and the primary analysis on community type through the Braun-Blanquet method of the four remnants show some common characters. These characteristics suggest that, in the past, the same vegetation may have dominated the landscape along the sandbars lying parallel to the seashore of Peninsular Thailand.
