In response to extensive deforestation in the Philippines in the last century, reforestation initiatives have been developed, setting area- or seedling count-based success criteria. However, to sufficiently assess reforestation as an approach to conserving biodiversity and protecting habitats, restoration of ecosystem integrity must be evaluated. Increased recognition of the role of fauna in ecological restoration has led to the evaluation of the role of different groups in assisting recovery and as potential metrics of success. In this study, we used mist netting data to evaluate how richness, abundance, diversity, and composition of fruit bats differ between reforestation areas and nearby secondary forest, and their potential as measures of restoration success. We captured 6564 fruit bats representing 15 species from a sampling effort of 1,994,366 m²·h. Estimated species richness and Simpson indices did not differ significantly between habitat types. Overall abundance was only significantly different in Palinpinon, with more individuals in the reforestation area, while Shannon indices only differed significantly in BacMan. Differences in composition were all found to be statistically significant, based on non-metric multidimensional scaling ordination biplots and permutational MANOVA. Of the three most abundant species captured across all reservations, the generalists Cynopterus luzoniensis and Macroglossus minimus were more abundant in reforestation areas. On the other hand, the forest specialists Haplonycteris fischeri, Harpyionycteris whiteheadi, and Ptenochirus minor showed lower abundances in reforestation areas. While univariate biodiversity metrics did not differ between secondary forests and reforestation areas, the abundance of particular species and the species composition of fruit bats remained distinct between these habitats. We identified specific aspects of the fruit bat assemblage with the potential as metrics of restoration success. To facilitate evaluation of restoration success using changes in faunal assemblage, we recommend the development of sampling protocols and metrics that would standardize this process.

为了响应上个世纪菲律宾的大规模毁林，已经制定了重新造林计划，设定了基于面积或幼苗数量的成功标准。但是，为了充分评估重新造林作为保护生物多样性和保护生境的一种方法，必须评估生态系统完整性的恢复。人们越来越认识到动物在生态恢复中的作用，从而评估了不同群体在帮助恢复中的作用以及作为成功的潜在指标。在这项研究中，我们使用薄雾网数据评估了再造林区和附近的次生林之间果蝠的丰富度，丰度，多样性和组成有何不同，以及它们作为恢复成功的潜力。我们从1,994个采样工作中捕获了代表15种物种的6564个果蝠，² ·小时。估计的物种丰富度和辛普森指数在生境类型之间没有显着差异。在Palinpinon，总体丰度只有显着差异，在重新造林地区有更多的个体，而在BacMan中，Shannon指数只有显着差异。基于非度量多维标度排序双标和排列MANOVA，发现成分差异均在统计学上具有显着性。在所有保留地中捕获的三个最丰富的物种中，通才Cynopterus luzoniensis和Macroglossus minimus在重新造林地区更为丰富。另一方面，森林专家Haplonycteris fischeri，Harpyionycteris whiteheadi和未成年Ptenochirus在重新造林地区的丰度较低。虽然次生林和复林区之间的单变量生物多样性指标没有差异，但这些生境之间特定物种的丰富度和果蝠的物种组成仍然不同。我们确定了果实蝙蝠组合的特定方面，并将其作为恢复成功的指标。为了便于使用动物组合的变化评估恢复成功的可能性，我们建议开发可标准化该过程的采样协议和度量标准。
