Recent research led by conservationists in Bhutan has harnessed environmental DNA (eDNA) technology to detect traces of snow leopards in some of the kingdom’s most inaccessible mountain waterways. By analyzing water samples collected from strategic river points, scientists have identified the genetic footprint of these elusive big cats, offering a groundbreaking non-invasive method to monitor populations without disturbing their fragile habitats. This innovative approach marks a significant advancement in wildlife monitoring, especially for species like the snow leopard, whose secretive nature and rugged terrain make traditional tracking methods challenging and costly.

The findings provide crucial insights into the snow leopard’s distribution along Bhutan’s remote rivers, enabling better-targeted conservation efforts. Key advantages of eDNA in this context include:

  • Minimal environmental disruption: Sampling water requires no direct animal contact or habitat alteration.
  • High sensitivity: Capable of detecting even faint traces of DNA, improving detection rates.
  • Cost-effective monitoring: Reduces the need for extensive field surveys and camera traps.
