Abstract

Structure and growth in teak forest 10 years after logging were studied at Mae Pung forest, Phrae province on March 1984. Line plot sampling was used. Eighty-eight curcular plots, each 12.62 m in radius were established. The total number of all trees (≥5.0 cm dbh) was recorded.


Size-class structure of all teak forest species and non-teak species were described by a negative exponential function but teak alone was not. After adjusting the size-class distribution of teak to that of a balanced uneven-aged forest (Leak 1965 and Meyer 1952), its desirable density was determined to be 193 trees/ha and density in each size-class was calculated.


Annual increment of the previous 5 years of teak (0.228 - 0.642 cm) was more than the previous 10 years (0.196 - 0.563 cm) in every size-class. Basal area and periodic annual increment of the next 10 years are calculated to be 16.58 m2 /ha and 0.213 m2 /ha/year.
