多龄造林在北美各地变化很大，但一个共同点是负指数直径分布的关系，以指导放养控制。这些方法已在若干区域得到发展，包括替代林分结构，目前正在开发新的种群控制工具。这些新发展的趋势是整合干扰机制及其对林分结构的影响。在某些情况下，其结果是朝着更长的采伐周期和更灵活的林分结构指导方针的方向发展。
Multiaged silviculture is highly variable across North America but a commonality is the ties to the negative exponential diameter distribution to guide stocking control. These methods have evolved in several regions to include alternative stand structures and new stocking control tools are being developed. A trend in these new developments is integrating disturbance regimes and their effects on stand structure. The result, in some cases, is a movement towards longer cutting cycles and more flexible guidelines for stand structure.
