Abstract: Some 2 000 hectares of Pinus contorta were planted in Karioi Forest, Central North Island, in 1928-33, and seed from this source has regenerated naturally over large areas of tussock lands adjoining the forest. These stands, predominantly of "green strain" (coastal provenances), could be managed for production of pulpwood or sawlogs if properly tended. Accordingly pruning and thinning were started in 1959 and some 300 ha had been treated up to 1972, at relatively low cost. These operations are described in detail.
