Planting trials of 10 Mexican pine species in Hawaii

Abstract

Ten species of Mexican pines were planted on adverse sites at 6450 feet (1970 m) elevation on Maui, and five species on similar sites at 3200 feet (975 m) elevation on Molokai, Hawaii. Initial survival was poor because of the low quality of the planting stock and harsh site conditions, but subsequent mortality was low. Growth and vigor has been satisfactory. Average annual height growth five years after outplanting ranged from 1 to 3 feet 0.3 to 1 m) on Maui and from 1 to 2 feet (0.3 to 0.6 m) on Molokai. Most trees showed good vigor. The results suggest that Mexican pines would be suitable for reforestation on adverse sites at the higher elevation in Hawaii.
