Abstract

Structure of hill evergreen forest at Huay Nam Dung Watershed Station, Chiang Mai Province was investigated during March 1983 to December 1984. The results of the study revealed that there were 56 species and 521 trunks (501 individuals) for trees larger than 4.5 cm in DBH in one hectare plot. The most abundant species is Castanopsis acuminatissema. Its dominance in the stand is decisive and stable, since the species maintains the top rank throughout the three layers of the forest. The vertical structure can be precisely divided into 3 layers at over 28 m, 18-28, and below 18 m, respectively. Moreover, the third layer might be subdivided in to two sublayers at 10 m high. The specific diversity as determined by the Shannon-Wiener index of diversity was 4.97.
