Abstract: Establishment of pines, principally Pinus contorta, by aerial seeding in Kaweka Forest, Hawke's Bay, was commenced in 1965 in an attempt to reduce erosion surfaces and to supplement alternative more costly methods of revegetation. Results indicate that, after five years, a satisfactory stocking of 620 to 740 s.p.ha can be achieved up to an altitude of 1,220 m. Stocking is affected by sowing rates, surface conditions, degree of slope, density of existing vegetation, altitude and exposure, and sites have been classified on the basis of these factors. The comparison of this technique with hand planting and mechanical seeding methods of revegetation is discussed.
