Description: The optimum interval at which to plant loblolly pine (Pinus taeda L.) is being studied on the island of Maui, Hawaii. Four spacings are being tried: 6, 8, 10, and 12 feet. Measurements of trial plots in 1968-7 years after plots were set up-show that (a) survival rate exceeded 95 percent; (b) height growth averaged about 30 feet in all spacings; (c) average d.b.h. increases ranged from 5.3 inches at the 6-foot spacing to 7.8 inches in the 12-foot spacing; and (d) basal area ranged from 95 sq. ft. per acre in the 12-foot spacing to 193 sq. ft. per acre in the 6-foot spacing.

Keywords: Pinus taeda, Hawaii, planting density, growth response
