Deforestation is a major threat to biodiversity, particularly within tropical forest habitats. Some of the fastest diminishing tropical forest habitats in the world occur in Indonesia, where fragmentation is severely impacting biodiversity, including on the island of Java, which holds many endemic species. Extreme fragmentation on the western part of the island, especially due to small-scale agriculture, impacts animal movement and increases mortality risk for mainly arboreal taxa. To mitigate this risk in an agroforest environment in Garut District, West Java, we installed 10 canopy bridges and monitored them through camera trapping between 2017 and 2019. Five of the monitored bridges were made of waterlines and five of rubber hose. We recorded Javan palm civets using the waterline bridges 938 times, while Javan slow lorises used the waterlines 1079 times and the rubber bridges 358 times. At least 19 other species used the bridges for crossing or perching. Our results demonstrate that relatively simple and cost-effective materials can be used to mitigate the effects of habitat fragmentation. We also recommend the use of camera traps to monitor the effectiveness of these interventions.

在印度尼西亚农林业环境中实施和监测哺乳动物和鸟类使用人工天棚桥的情况

毁林是对生物多样性的主要威胁，特别是在热带森林栖息地内。世界上某些减缓最快的热带森林栖息地发生在印度尼西亚，那里的碎片化严重影响了生物多样性，包括爪哇岛上的爪哇岛，该岛拥有许多特有物种。岛屿西部地区的极端支离破碎，特别是由于小规模的农业生产，影响了动物的活动并增加了主要为树木类群的死亡风险。为了缓解西爪哇省Garut区农林环境中的这种风险，我们在2017年至2019年之间安装了10个顶篷桥，并通过摄像头捕获对其进行了监控。其中5个被监控的桥由水线组成，另外五个由橡胶软管制成。我们用水线桥录制了Javan棕榈香椿938次，而爪哇慢干猴则使用水线1079次，橡胶桥358次。至少有19个其他物种使用桥梁进行过境或栖息。我们的结果表明，可以使用相对简单且具有成本效益的材料来减轻栖息地破碎化的影响。我们还建议使用摄像头陷阱来监视这些干预措施的有效性。
