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
