Many plants resprout from basal buds after disturbance, and this is common in shrublands subjected to high-intensity fires. However, resprouting after fire from epicormic (stem) buds is globally far less common. Unlike basal resprouting, post-fire epicormic resprouting is a key plant adaptation for retention of the arborescent skeleton after fire, allowing rapid recovery of the forest or woodland and leading to greater ecosystem resilience under recurrent high-intensity fires. Here we review the biogeography of epicormic resprouting, the mechanisms of protection, the fire regimes where it occurs, and the evolutionary drivers that shaped this trait. We propose that epicormic resprouting is adaptive in ecosystems with high fire frequency and relatively high productivity, at moderate–high fire intensities.

许多植物在受到干扰后会从基芽中萌芽，这在遭受高强度大火的灌木丛中很常见。但是，在全球范围内，从表皮（茎）芽着火后再发芽的情况在全球范围内很少见。与基础重生不同，火灾后的表皮重生是火后保留树状骨骼的关键植物适应方法，可以使森林或林地迅速恢复，并在反复发生的高强度大火下产生更大的生态系统适应力。在这里，我们回顾了表皮重生的生物地理学，保护机制，发生火灾的方式以及形成该特征的进化驱动因素。我们建议，在中等至高火强度下，表皮重生能够适应高发火频率和较高生产率的生态系统。
