Abstract: Clear wood of New Zealand grown Pinus radiata has excellent physical properties which commend it for a very wide range of uses. Sawn timber from the unthinned and unpruned stands now being felled, however, yields too high a proportion of low grades. The capacity of the species to yield a large volume of good quality wood in a given time suggests that pruning of butt logs is economically justifiable and nationally essential to meet domestic needs for high utility clear timber and peeler logs in the near future. If stands can be managed on longer rotations, there are notable advantages to be gained also from heartwood and from an all round increase in density
