Tiger use of Biological Corridor 7 confirmed
Divisional Forest Office, Mongar, is pleased to share new scientific evidence confirming the use of Biological Corridor 7 (BC7) by a tiger (Panthera tigris).
A study recently published in Oryx documented an adult male tiger at two locations within BC7 during a 2025 camera-trap survey. While further monitoring is needed to confirm movement between adjoining protected areas, the finding provides important evidence that a wide-ranging large carnivore is using the corridor.

The finding is particularly important as major infrastructure developments are taking place within BC7. One hydro project lies in the southern section of the corridor, while another proposed hydro project will affect its north-eastern part.
A biological corridor can serve its purpose only when wildlife can continue to move through it. Roads, hydropower infrastructure and other developments therefore need careful planning, with suitable wildlife crossings, protection of key habitats and movement routes, and continued monitoring.
A related study on prey occupancy and functional connectivity identified seven major pinch-point zones within BC7, further highlighting areas where conservation measures should be prioritised.

These studies show that development and conservation need not compete. With proper planning and wildlife-friendly mitigation measures, development can proceed while maintaining BC7's ecological function.
Division and authors gratefully acknowledge the financial support received from the Mohamed bin Zayed Species Conservation Fund, Bhutan Ecological Society, and Bhutan Trust Fund for Environmental Conservation; camera-trap support from the Nature Conservation Division; and the contributions of all field staff and institutions involved in the research.
The evidence is now available; the next step is to ensure that wildlife continues to have space to move through BC7.
