使用来自选定西部林地的数据对燃料处理造林和由此产生的生物量长期流动进行了检查。建立了储备树不均龄管理制度，以优势树冠层封闭率为 40% 为目标，采伐周期为 20 年。目前库存过剩的机架中的燃料减少处理导致了第一和第二切割周期的初始去除高峰。在随后的切削周期中产量稳定。清除一些大型储备树木对于维持林分结构和防火能力至关重要。
Fuel treatment silviculture and the resulting long-term flow of biomass were examined using data from selected western stands. An uneven-aged management regime with reserve trees was modeled, using a canopy closure of 40 percent for the dominant trees as a target and a harvest cutting cycle of 20 years. Fuel reduction treatments in currently overstocked stands resulted in an initial peak of removal for the first and second cutting cycles. Yields stabilized in subsequent cutting cycles. Removal of some large reserve trees was crucial for maintaining stand structure and fire resilience.
