The Ranong research site was established in the mangroves in the campus of Andaman Coastal Research Station, Kasetsart University and its vicinities surroundings. The original study organized here in 2003 was on the stand productivity and litter amount including leaf, branch and whole tree as coarse litter produced by mangroves. The stand dynamics, e.g. growth and death were monitored in individual base. Just one month after the 2nd census in November 2004, Tsunami slaughtered and left untold damage and death to the wide area surrounding Andaman Ocean. This area was also severely damaged both in nature and human settlements. The census plots were also damaged but trace-able. The damage appearing gradually over long term and the recovery from that damage were then be included as the another objective of dynamic study here.
