Udaipur, March 18, 2025 - India’s first frozen zoo has been set up at the Padmaja Naidu Himalayan Zoological Park in Darjeeling. This unique facility is preserving the DNA of rare Himalayan animals to protect them from extinction. The frozen zoo in Darjeeling keeps DNA samples in steel tanks filled with liquid nitrogen at -196°C. Scientists collect tissue from animals, especially those that die naturally or in accidents like road kills.

Collaboration for Conservation

The project is a joint effort between the Darjeeling zoo and Hyderabad’s Centre for Cellular and Molecular Biology. Bengal’s Chief Wildlife Warden, Debal Roy, explained that this initiative helps preserve the genetic blueprint of endangered species.

Animals Being Preserved

• Red pandas
• Snow leopards
• Himalayan black bears
• Gorals
• Mishmi takins
• Tibetan wolves
• Markhors (screw-horned goats)

Future Uses of Frozen DNA

Stored genetic material could help in assisted reproduction, possibly even bringing back endangered species using surrogate mothers. As long as there is a steady supply of liquid nitrogen, these tissues can be preserved indefinitely. The frozen zoo’s efforts have been recognized globally. The World Association of Zoos and Aquariums has shortlisted it for its red panda conservation program.

What is a Frozen Zoo?

A frozen zoo is a facility that stores genetic material from animals in extremely cold temperatures. This ensures that their DNA remains safe even if their numbers decline in the wild. With climate change and habitat loss affecting wildlife, the frozen zoo could play a crucial role in preventing species from disappearing forever.
