This is a report on the "Kayaze-Hiba" stand. The "Hiba" stands are the common forest in Aomori District but they are very rare in Kyushu. The results of comparison of the "Hiba" stand in Kyushu with t...he data of the "Hiba" stands in Aomori District are summarized as follows: (1) Number and volume per unit area are nearly the same, in spite of the differences in the land and climatic features. (2) Distribution of the stem number by diameter grade and of the stem number by single tree volume grade are near by normal, but that of the stem number by height grade is uniform. (3) Growth of this stand is greater than that in Aomori District. (4) Current annual growth in volume is greater than the mean annual growth, even the trees are old. (5) Tree form is tapering when young, but gets full bole at middle and old ages.続きを見る
