Figure 28.-Evergrten Moist forest fringing the Korat Plateau. In Thai
land, Evergreen Rain or Moist forest is confined mostly to the southeastern
and southern provinces around the Golf of Thailand. A stretch
of Evergreen forest occurs also on the southern and southwestward slopes
where the Korat Plateau drops into the central plain. In this forest
type, trees reach 90 to 130 feet (20-^0 ra.) in height, are often buttressed,
and with dense, continuous canopy, Northwest of Nakhcn Hayek,
east-central Thailand.

Figure ,;9.-Upper Moist Evergreen forest in Khao Yai National Forest. The
canopy and understories are dense, so that horizontal (ground-to-ground)
and vertical (air-to-ground) visibility are poor in this forest type.
Such medium-sized trees as species of oak (Quercus), chestnut (Castanopsis),
Podocarpus, Lithocarpus and Dacrydium occur in the Lower Montane forest
on the upper slope and on the summit"of Khao Kheo Range (background).
