Maate is a forma of Thujopsis dolabrata SIEB. et ZUCC. var. hondai MAKIN0, and Maate forest has been managed to produce material for laquered ware and construction timber in Noto area. Maate stand by selection method has been regenerated with layering method and the regeneration repeated at the age of seedling.
Three stands were investigated on their structure and the outline was given in Table 2.
Current annual volume increment per ha. of Konosu, Yamamoto and Futamata stands is 10.3m^3, 15.2m^3 and 15.9m^3 respectively. This range (10.3~15.9m^3) of volume increment of the selection forest is nearly equal to the maximum of mean volume increment(12.5m^3) of Site Quality I of Ate yield table.
Konosu stand is youngest in age, lowest in height and fairly understocked among three stands. Owing to these characteristics of stucture the growth of Konosu stand is different from that of other two stands, therein, at Konosu stand current annual increment in diameter and height of lower storied trees is very vigorous, while that of Yamamoto and Futamata stands is small(Fig.3, 4 and 5). But the growth of upper storied trees of three stands is very good.
