We examined the worldwide literature on biodiversity in forest plantations for the indicator organism assessed, species composition (native versus exotic), tree species diversity, and appropriateness of the comparisons made. Fifty percent of the studies used invertebrates, 36% birds, 6% mammals, and 6% vascular plants as bioindicators. We found that 76% of the existing literature compares exotic plantation forests to native/natural forests, 9% of studies compare native plantations to native/natural forests, and 3% examine plantations to plantations. Lower biodiversity in plantation forest compared to other forests was reported by 94% of the reviewed studies. However, some studies indicate higher biodiversity in plantation forests compared to other land uses such as agriculture. We argue that much of the literature reporting lower biodiversity in plantation forests is based on inappropriate comparisons. We suggest more appropriate approaches to assessing the effects of plantation forests on biodiversity.

人工林和生物多样性：新视角

我们审查了有关人工林生物多样性的全球文献，以评估评估的指示生物、物种组成（本地与外来）、树种多样性以及进行比较的适当性。 50% 的研究使用无脊椎动物、36% 的鸟类、6% 的哺乳动物和 6% 的维管植物作为生物指示剂。我们发现，76% 的现有文献将外来人工林与原生/天然森林进行比较，9% 的研究将原生人工林与原生/天然森林进行比较，3% 的研究将人工林与人工林进行比较。 94% 的审查研究报告称，与其他森林相比，人工林的生物多样性较低。然而，一些研究表明，与农业等其他土地利用相比，人工林的生物多样性更高。我们认为，许多报道人工林生物多样性较低的文献都是基于不适当的比较。我们建议采用更合适的方法来评估人工林对生物多样性的影响。
