Popis: A system model for estimating short-rotation, intensive-culture woody biomass production costs, including establishment, maintenance, harvesting, and transport costs, was developed and applied to the island of Kauai. Using data from existing large-plot field trials, biomass yield of the tropical hardwood Eucalyptus saligna was predicted from site-specific factors such as local weather and soil conditions and management strategies. Possible harvesting systems were identified and associated harvesting costs were estimated. The distances from the plantation sites to a bio-conversion plant located at the Lihue sugar mill were calculated based on existing road networks. The delivered cost of biomass on a dollar per dry metric ton (Mg) basis was then calculated using a discounted cash flow method. A geographic information system was interfaced with the biomass system model to access a database and present results in map form. Under the most favorable management strategy modeled, approximately 330 x 103 dry Mg year−1 of Eucalyptus saligna could be produced from 12,000 ha at a delivered cost of $25–38 per dry Mg chips.
