Abstract

Integrated forest products from former sugarcane plantations in Hawaii.

Abstract

In order to help landowners and land-use planners evaluate potential forest product ventures on former sugarcane lands in Hawaii, a short-rotation forestry decision support system was developed. An application to estimate annual net returns of hypothetical integrated forest product operations established at 2 former sugarcane plantations (the Hamakua plantation on the island of Hawaii, and the Waialua plantation on Oahu) is featured. From a variety of plantation management and wood processing options, linear programming results indicate that the optimal profit opportunity exists for the production of medium density fibreboard and plywood from Eucalyptus saligna plantations, with annual net return estimates of approximately $3.5 million ($8970/ha) from 3 commercial thinnings (at 5, 10, and 15 yr old) and one harvest at rotation age (20 yr) from the Hamakua plantation area, and $2.2 million ($4880/ha) from 2 commercial thinnings (at 4 and 10 yr old) and one harvest at rotation age (15 yr) on the Waialua plantation area.
