为了满足对肉类和木材产品日益增长的需求，全球范围内建立了更多的牧场和森林种植园。牧场和种植园的扩张往往导致森林砍伐，造成生物群落的同质化，是全球灭绝危机的主要驱动力。一个核心问题是，损失的严重程度在牧场和种植园之间有何不同，而反过来，地理位置和种植园管理特点又如何缓和这些影响。（两栖动物和爬行动物）作为最濒危的脊椎动物群体，我们使用41篇科学文章进行了全球综合，这些文章报告了191年牧场和林业种植园相对于天然林的物种丰富度或丰度。在19个国家的案例研究中，我们发现了一个严重的负面影响，牧场和林业种植园的负面影响较小的物种丰富度和丰富的两栖动物区系。在种植园内，物种丰富度和总丰度更负面的影响，两栖动物比爬行动物，在热带地区，当种植外来树种，单作，大型或商业种植园，并清除林下植被。然而，混合，老，小或保护人工林和那些允许恢复林下植被没有负面影响相对于参考天然林。两栖爬行动物物种丰富度和数量的丧失突出表明，必须停止目前为牧场和集约林业种植园而砍伐热带森林的做法。在缺乏森林覆盖的地区，适当管理的植树造林具有支持生物多样性的潜力，包括通过取代人为牧场，这表明这种植树造林在全球重新造林议程中发挥重要作用。
The establishment of pastures and forestry plantations has increased globally to meet growing demands for meat and wood products. Pasture and plantation expansion often drives deforestation, which causes homogenization of biotic communities and is a major driver of the global extinction crisis. A core question is how the severity of losses varies between pastures and plantations, and in turn, how geographical location and plantation management characteristics moderate these impacts.Focusing on herpetofauna (amphibians and reptiles) as the most endangered vertebrate group, we performed a global synthesis using 41 scientific articles that reported species richness or abundance in pastures and forestry plantations relative to natural forest in 191 case studies among 19 countries.We found a severe negative effect of pasture and a less negative effect of forestry plantations on species richness and abundance of herpetofauna. Within plantations, species richness and total abundance were more negatively impacted in amphibians than reptiles, in the tropics, when planting exotic tree species, monocultures, large or commercial plantations, and when clearing understory vegetation. Yet mixed, old, small or conservation plantations and those permitting recovery of understory vegetation had no negative impacts relative to the reference natural forest.Synthesis and applications. The loss of herpetofauna species richness and abundance underscores the importance of halting ongoing tropical deforestation for pasture and intensive forestry plantations. The potential for appropriately managed forestry plantations to support biodiversity in regions lacking forest cover, including via replacement of anthropogenic pastures, suggests that such plantations have an important role under global reforestation agendas.
