Change in the stand structure of a natural fir-hemlock-hardwood secondary mixed stand in the Ehime University Forest. (I) Development of the growing-stock of the main stand from 1968 to 1980. (Analysis from the viewpoint of management by the check method)

Data collected for trees of d.b.h. 8 cm or more showed that the number of trees recruited into the smallest class decreased from 125 stems/ha over period I (1968-74) to 80 stems/ha over period II (1974-80). Most (95%) of these were broadleaved trees; no hemlock was recruited. Mortality increased from 59 dead standing stems/ha in period I to 68 stems/ha in period II. Most dead stems were <13 cm d.b.h. and about 80% were broadleaves.
