Roads and other forms of human linear infrastructure present some of the most substantial threats to ecosystems globally. Roads are a major source of direct mortality through collisions with vehicles, and along with other forms of linear infrastructure, roads bisect habitats, causing the isolation of wildlife on either side. The good news is that canopy bridges, artificial and natural crossing structures over linear infrastructure, have become increasingly implemented to solve this fragmentation problem.

The December issue “Canopy bridges for conservation: Case studies from around the world” of Brill’s Folia Primatologica is dedicated to the topic of canopy bridges, and nearly doubles the literature on this topic. This special issue contributes substantially to the understanding of canopy bridges, including species' use of different designs, involved costs and materials, and effective and innovative monitoring methods.

The studies show that it is clear that a broad diversity of species is benefitting from these bridges, and illustrate the increasing sophistication of canopy bridge research with growing interest by canopy bridge researchers in testing different designs and monitoring methods. The transfer of knowledge between research teams will allow the implementation of canopy bridges to be scaled up globally and the challenge of a growing road network to have mitigation solutions for arboreal species.

About Folia Primatologica
Folia Primatologica is a bimonthly international peer-reviewed journal focused on primatology: the study of monkeys, lemurs, apes, and other primates. It was founded in 1963 and covers diverse areas of primatology including conservation, ecology, paleontology and social behavior.
