The purposes of this study were to promote the public interest in forests concerning with watersource conservation and land conservation, and to produce high-price trees by improving the productivity of the stand, by the selective cutting system for the broad leaved forest in Okinawa. As a guide of the selective cutting system for the actual broad leaved stand, the practically applicable methods were considered as follows; (1) a method to lead to the selective cutting after establishing the forest by the regeneration of sprout, (2) a method to lead to the selective cutting after applying salvage cutting to improve the actual stand, and (3) a method to carry out the selective cutting directly to the actual forest. In the seperate article, the case of method (1) was reported, and the outline of the established test plots and the stand composition of the plots before cutting were described in the present paper as the case of method (2). In order to establish a suitable management method of the selective cutting system for the broad leaved forest in Okinawa, it was considered to be necessary that the many experimental plots in each case should be established in various land descriptions, and that a comprehesive investigation covering changes of growth and quality of the sapling, underplant vegetation and waterholding of the soil etc. must be carried out for a long period.
