Biomass measurements at Pa Dieow Dai.

​

The height at the top of this sandstone mesa is around 1000m, 600m higher than the moist evergreen forest near Km33 and Nong Pak Chee. The mountain gets water even in the dry season as mists cloak the forest and water condenses on the vegetation. It is cooler, windier and wetter. The trees here are different with oaks and chestnuts more dominant than the dipterocarps and ficus found at lower levels.

 

The swamp forest is fragile and should not be trampled so make the measurements on the 1m strip each side of a 50m section of the boardwalk.
