摘要：Land use changes and timberland use by ownership and forest type in Alabama and Georgia between 1972 and 2000 are analyzed using a modified multinomial logit approach. Low average land quality, federal cost-share incentives, and favorable returns to forestry relative to agriculture were the main factors associated with timberland increase. Higher forestry returns helped increase industrial timberland but not nonindustrial private forests. An increase in hardwood forests at the expense of softwood and mixed forests was driven by increasing hardwood returns. Increasing softwood returns and tree planting assistance programs alleviated declines in softwood forests. Because factors influencing timberland use changes differ by ownership and forest type, treating all timberland as one major category may lead to incorrect predications.
