Tropical forests are among the most biodiverse—and most threatened—ecosystems on Earth. Our work is grounded in the belief that understanding and conserving these ecosystems is urgent and essential.
We strive to:
Understand ecology and evolution of species and their roles in tropical ecosystems.
Understand how human activities affect biodiversity—from genes to communities.
Restore degraded forests and ecological functions.
Raise awareness about threatened species and ecosystems.
By focusing on neglected yet highly threatened species and habitats, we aim to fill critical knowledge gaps that can guide and prioritize conservation efforts. We work across four global Biodiversity Hotspots—the Himalaya, Western Ghats, Indo-Myanmar, and Sundaland—studying woody plants, amphibians, reptiles, birds, and mammals.

Our program’s name—CEROS—is inspired by the Latin name for hornbills (e.g., Buceros), reflecting our origins in research and conservation of hornbill species. While hornbills remain a key focus of our work across South and Southeast Asia, we have since expanded to include other threatened species and ecosystems. The name CEROS also loosely encapsulates the core of our work: Community Ecology and Restoration in the Sahyadris.
