Abstract Forest restoration may support recovery and conservation of biodiversity. However, the response of biodiversity to forest restoration is likely to vary depending on the restoration strategy used and taxa considered. Our goal was to assess the recovery of amphibians, a highly threatened biological group, in three cloud forests under different restoration strategies. We compared different measures of species diversity in cattle pasture, 13-year-old forest under passive restoration (P13), 23-year-old forest under passive restoration (P23), 23-year-old forest under active restoration (A23) and mature cloud forest in Mexico. We sampled amphibians in 45 plots and measured landscape and habitat variables to assess their influence on amphibian recovery. We found a total of 13 amphibian species, of which 23% are in the Vulnerable (VU) category of the IUCN Red List and 15% are Critically Endangered (CR). All forests under restoration recovered amphibian species richness and composition, including that of the threatened species, but abundance differed among restoration strategies. Abundance of VU and CR species was higher in A23 than in P13 and P23, but that of CR species was highest in cloud forest. Responses to forest restoration differed among taxa; recovery of salamanders was lower than that of anurans. Proximity to water bodies, as well as high canopy and leaf litter cover, had a strong positive influence on amphibian recovery. Our results indicate that recovery of threatened biodiversity could be promoted through forest restoration, particularly active restoration, and highlight the essential role of mature forest in the maintenance and recovery of amphibian communities.

森林恢复是否有助于受威胁物种的恢复？云林两栖动物群落研究

摘要 森林恢复可以支持生物多样性的恢复和保护。然而，生物多样性对森林恢复的反应可能因所使用的恢复策略和考虑的分类群而异。我们的目标是评估两栖动物（一种高度受威胁的生物群落）在不同恢复策略下在三个云雾林中的恢复情况。我们比较了牛牧场、被动恢复下的 13 年生林（P13）、被动恢复下的 23 年生林（P23）、主动恢复下的 23 年生林（A23）和墨西哥成熟的云雾森林。我们在 45 个地块中对两栖动物进行了采样，并测量了景观和栖息地变量，以评估它们对两栖动物恢复的影响。我们一共发现了13种两栖动物，其中 23% 属于 IUCN 红色名录的易危 (VU) 类别，15% 属于极危 (CR)。所有正在恢复的森林都恢复了两栖动物物种的丰富度和组成，包括受威胁物种的丰富度和组成，但不同恢复策略的数量不同。A23 中 VU 和 CR 物种的丰度高于 P13 和 P23，但云林中 CR 物种的丰度最高。不同分类群对森林恢复的反应不同；蝾螈的回收率低于无尾目。靠近水体以及高树冠和落叶覆盖对两栖动物的恢复有很强的积极影响。我们的结果表明，可以通过森林恢复，特别是积极恢复，促进受威胁生物多样性的恢复，
