Wildlife overpasses are used as a mitigation measure worldwide to reduce the mortality of wildlife on roads, and to a certain extent, to facilitate the genetic exchange of both flora and fauna species in forest fragments. This photo depicts a newly constructed wildlife overpass in highly urbanized Singapore, which connects two rainforest nature reserves that was separated by an eight-laned highway for close to 30 years. Rainforest afforestation on the overpass with the appropriate plant species will be crucial in forming a functional wildlife corridor between the two fragments. The success of such a mitigation technique can only be shown with the careful planning of monitoring programs (using camera traps and passive ultrasonic recordings) and genetic studies of target animal groups.
