The production structure of the Kusa-Ate selection forest was investigated at Monzen cho, Ishikawa Prefecture.
The results are as follows :
1. The relation between number of trees and D. b. h. was shown as Meyer's fomula.
2. The allometry of a single tree was calculated by sample trees, and the biomass of the forest was estimated by these equations.
3. The dry weight of stem, branch and foliage was amounted to 151.2, 19.5 and 31.9 ton, respectively.
4. The current annual increments of the forest were estimated 17.5m^3 per ha, and the value is as large again as the mean increment of Kusa-Ate even-aged forest at tlhis district.
