A quiet move that has kept Dehradun’s vultures safe, Pg9

Key Highlights:

• A study in Dehradun, Uttarakhand, identified electrocution from high-tension power infrastructure as a significant threat to vultures.
• Between May 2011 and February 2014, 46 vulture electrocution deaths were documented in the Sudhauwala region.
• The Himalayan griffon, Eurasian griffon, and Cinereous vulture were the most affected species.
• Local authorities relocated a livestock carcass dumping site 2.4 km away from hazardous power lines in April 2015.
• Post-relocation monitoring indicated no further electrocution mortalities at the new site.

Detailed Insights:

• Vultures in India face multiple threats including poisoning, veterinary Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), food scarcity, and habitat loss.
• The study, published in the Journal of Threatened Taxa, highlighted electrocution as an underreported but significant localized threat.
• The relocation of the carcass dump served as a practical and effective conservation measure to mitigate electrocution risk for these long-lived scavengers.
• This successful intervention suggests that similar strategies could be applied in other regions facing comparable challenges for vulture conservation.
• Other raptor species, such as the black kite and crested serpent eagle, were also observed benefiting from the relocated site.
• While effective, no further studies have been conducted since 2015 to assess the long-term impact and sustainability of this measure.

Scientific/Technical Concepts Involved:

• Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): A class of drugs, like diclofenac, that are highly toxic to vultures when consumed through the carcasses of treated livestock.
• Himalayan Griffon (Gyps himalayensis): A large Old World vulture species native to the Himalayas and the Tibetan Plateau, known for its scavenging habits.
• Electrocution: The injury or death of an animal caused by electric shock, often resulting from contact with high-voltage power lines or infrastructure.
