The Center for Large Landscape Conservation conducted a one-year pilot project to assess major threats to apes, gibbons, and human communities from linear infrastructure across three pilot landscapes; Northern India, Peninsular and Eastern Sabah Borneo Malaysia, and Transboundary Virunga. We focused on three research approaches to better understand best practices for LI safeguards to protect apes, their habitat, and ecological connectivity. In collaboration with on-the-ground conservation practitioners, we collected the best available scientific and policy advice, case studies, research, and analyses to better understand the current state of knowledge and make recommendations for future research and conservation efforts. This podium presentation will highlight a variety of case studies, including best practices for the implementation of arboreal bridges, mitigation measures to reduce primate electrocutions, and the importance of multistakeholder coalitions. We will also discuss critical gaps in knowledge and make recommendations for further research opportunities.
