Seagrass beds in Thai coastal waters of the Andaman sea were surveyed from 1988 to 1992. Aerial photographs (scale 1:15,000) were used for identification of potential sites for ground surveys. Salinity, water transparency, depth profile, and sediment composition were classified: 1) mangrove-associated beds. 2) beds on broad, shallow sand bottoms, and 3) beds associated with coral reefs. Seagrass beds on shallow sandy bottom were the most common. Effects of man-made perturbations such as push-net fishing and siltation are believed to be responsible for degradation of seagrass beds in many areas under investigation.
