| Outline of Final Research Achievements |
A novel method was developed for estimating leaf biomass of evergreen hinoki cypress based on the pipe model theory. The analysis of felled trees in seven areas indicated that leaf biomass of hinoki cypress was proportional to the basal area at the lowest crown and the proportion constant was positively correlated with mean annual temperature of the study site. The findings suggest that leaf biomass would be simply estimated from diameter at the breast height, tree height, height at the lowest crown, and mean annual temperature. The applicability of the method was evaluated for thinned forests and forests along a topographic gradient.
