Most tropical forests have been logged. A major limitation on recovery is the growth of epiphytic lianas, which comprise ~20% of biomass in logged forests. While lianas inhibit tree growth, prevent seedling recruitment, and increase tree mortality, they provide vital resources for fauna including fruits, foraging opportunities, and shelter. To facilitate forest recovery, large-scale liana cutting has been initiated, but the long-term effectiveness is poorly understood. In 2019, we initiated a liana cutting experiment in ~350 hectares of logged forest in Borneo. Our experiment is the first globally to apply liana cutting at a range of intensities (plus uncut controls) and monitored pre-cutting plant, dung beetle and acoustic (including bird) diversity. This ACCE PhD project will utilize this unique experiment to understand the consequences of liana cutting for carbon stocking and biodiversity.

大多数热带森林已被砍伐。恢复的一个主要限制是附生藤本植物的生长，占采伐森林生物量的20%左右。虽然藤本植物抑制树木生长，防止幼苗补充，并增加树木死亡率，但它们为动物提供了重要的资源，包括水果，觅食机会和住所。为了促进森林恢复，已开始大规模砍伐藤本植物，但对长期效果知之甚少。2019年，我们在婆罗洲约350公顷的伐木林中开展了藤本植物切割实验。我们的实验是全球第一个应用藤本植物切割在一系列的强度（加上未切割的控制）和监测切割前的植物，粪甲虫和声学（包括鸟类）的多样性。这个ACCE博士项目将利用这个独特的实验来了解藤本植物切割对碳储存和生物多样性的影响。
