人口和经济增长率以及私人森林管理的强度只是影响美国林业部门长期前景的更广泛条件中的三个。同样重要的不确定性来源包括利率趋势、林产品消费的物种和产品组合、木材能源使用、林产品出口、加拿大木材成本、木材和纤维加工技术改进率以及国家森林采伐水平。仅其中少数条件的同时变化就可能导致森林部门的未来趋势与美国森林资源日益稀缺的传统预期显着不同。
Rates of population and economic growth and the intensity of private forest management are but three of a much broader array of conditions influencing the long-term outlook of the U.S. forest sector. Equally important sources of uncertainty are trends in interest rates, the species and product mix of forest products consumption, use of wood for energy, forest products exports, the cost of wood in Canada, rate of technical improvement in wood and fiber processing, and levels of national forest harvests. Simultaneous changes in only a few of these conditions can lead to future trends in the forest sector that differ significantly from traditional expectations of increasing forest resource scarcity in the United States.
