A significant increase in treatment pace and scale is needed to restore dry western US forest resilience owing to increasingly frequent and severe wildfire and drought. We propose a pyrosilviculture approach to directly increase large-scale fire use and modify current thinning treatments to optimize future fire incorporation. Recommendations include leveraging wildfire’s “treatment” in areas burned at low and moderate severity with subsequent pyrosilviculture management, identifying managed wildfire zones, and facilitating and financing prescribed fire with “anchor,” “ecosystem asset,” and “revenue” focused thinning treatments. Pyrosilviculture would also expand prescribed-burn and managed-wildfire objectives to include reducing stand density, increasing forest heterogeneity, and selecting for tree species and phenotypes better adapted to changing climate and disturbance regimes. The potential benefits and limitations of this approach are discussed. Fire is inevitable in dry western US forests and pyrosilviculture focuses on proactively shifting more of that fire into managed large-scale burns needed to restore ecosystem resilience.

美国西部干旱森林的景观恢复力需要火成林

由于野火和干旱日益频繁和严重，需要显着提高处理速度和规模，以恢复美国西部干旱的森林恢复力。我们提出了一种火法造林方法，以直接增加大规模火灾的使用，并修改当前的疏伐处理，以优化未来的火灾结合。建议包括利用野火对轻度和中度烧毁地区的“治疗”以及随后的火法造林管理，确定管理的野火区，并通过“锚点”、“生态系统资产”和“收入”重点疏伐治疗来促进和资助规定的火灾。火成林还将扩大规定燃烧和管理野火​​的目标，包括降低林分密度、增加森林异质性、并选择更适应不断变化的气候和干扰机制的树种和表型。讨论了这种方法的潜在好处和局限性。在干燥的美国西部森林中，火灾是不可避免的，火法造林的重点是主动将更多的火灾转移到恢复生态系统恢复能力所需的可控大规模烧伤上。
