Briefings

Nepal and a U.S. researcher tested artificial scent stations in Khata Corridor, Nepal, in March 2025. A Bengal tiger approached an iron stake releasing a chemical mimic of natural territory scents, then turned away. Researchers caution this does not yet prove the method prevents livestock attacks, noting it is not solid evidence that compounds reliably alter predator behavior.

Key points

• In March 2025, a Bengal tiger approached an iron stake in Nepal's Khata Corridor releasing a chemical mimic of natural territory scents, then turned away.
• Researchers caution that the tiger turning away is not solid evidence that the method prevents livestock attacks, as it is not yet proven that compounds reliably alter predator behavior.

Context

This experiment occurred in Nepal's buffer zone, where encounters with tigers and leopards have led communities to use electric fences and other deterrents. The article was originally published on Mongabay.

Limitations

Evidence is limited to one instance of a tiger turning away from a station; this does not constitute solid proof that the method prevents livestock attacks. Researchers note the study is at an early stage and caution that the method has not yet been proven effective.
