Over the past two decades, more than half a million acres of forested land has experienced extensive insect- and disease-caused tree mortality within the USDA Forest Service Rocky Mountain Region 2 (R2) of the National Forest System. To plan for timber harvest treatments needed to restore forest health, managers need information on forest product facility capacity and capability to profitably process timber of various size classes. To answer this need, the authors summarized timber harvest volumes by state and county group, identified facilities in the R2 area, quantified timber-processing capacities and size class capabilities, and analyzed the geographic variability of timber flows from county of harvest to mill. Results showed that nearly 285.5 million board feet Scribner of timber flowed from the study area to 101 processors throughout the R2 timber-processing area. Approximately 70 percent of annual milling capacity can profitably process trees ≧10 in. dbh, whereas just 8 percent can process timber <7 in. dbh. When planning forest-management activities, land managers should balance the need to remove small and/or dead trees with the local industry’s ability to profitably use that material.

美国农业部森林服务处落基山地区木材加工区的木材使用，加工能力和能力

在过去的二十年中，在国家森林系统的美国农业部落基山地区2（R2）内，超过半百万英亩的林地经历了由昆虫和疾病引起的大量树木死亡。为了规划恢复森林健康所需的木材采伐处理，管理人员需要有关林产品设施能力以及能够盈利地加工各种规格木材的能力的信息。为了满足这一需求，作者总结了各州和各县组的木材采伐量，确定了R2地区的设施，量化了木材加工能力和规模等级能力，并分析了从采伐县到工厂的木材流向的地理变异性。结果显示将近285。500万板英尺Scribner木材从研究区域流向整个R2木材加工区域的101个处理器。每年约有70％的采伐能力可以有益地处理≥10 in。dbh的树木，而只有8％的企业可以处理<7 in。dbh的木材。在计划森林管理活动时，土地管理者应在清除小树和/或枯木的需求与当地企业盈利使用该材料的能力之间取得平衡。
