India's 'Frozen Zoo' to Save Endangered Species
As a pioneering effort to protect its vast biodiversity, India has commissioned its first "frozen zoo" at the Padmaja Naidu Himalayan Zoological Park (PNHZP) in Darjeeling, West Bengal. This cutting-edge institution will store the genetic material of endangered species, providing a glimmer of hope for conservationists in the country.
The Concept of a Frozen Zoo
A "frozen zoo" is a biobank that harvests and stores genetic materials—DNA, tissues, and reproductive cells—of different animal species, especially those threatened or endangered. By cryopreserving the materials at ultra-low temperatures, usually in liquid nitrogen at -196°C, researchers can keep genetic information viable forever. The repository is a genetic library that allows future research, assisted reproduction, and even possible species revival programs.
Creation of India's First Frozen Zoo
The PNHZP, known for its work in preserving Himalayan wildlife, opened India's first biobank in a zoo in July 2024. This program, which has been functional since its opening, has been able to harvest DNA and tissue samples from 60 animals from 23 species, with the major emphasis being on endangered species.
Importance of the Darjeeling Frozen Zoo
The region of the Eastern Himalayas, where the Darjeeling Zoo is situated, is a hotspot of biodiversity, comprising more than 300 mammal species. Yet, habitat loss, poaching, and climate change threaten many of these species. The frozen zoo mitigates these problems in the following ways:
Sustaining Genetic Diversity: By keeping genetic material from wild populations, the biobank maintains a wider gene pool, which is essential for the health and survival of species.
Aiding Assisted Reproduction: The stored genetic materials can be used in assisted reproductive methods, like artificial insemination, in-vitro fertilization, or embryo transfer, to strengthen population levels.
Aiding Research: The repository of genes offers priceless material for genetic research on genetics, disease resistance, and adaptation of species, guiding conservation measures.
Global Scenario and India's Role
Frozen zoo concept has been around for some time; the first one was set up in San Diego back in 1972 and today has more than 8,400 samples from more than 800 species. India's entry into this field is a crucial turning point towards acting in sync with international conservation strategies. Before the Darjeeling facility was set up, the Laboratory for the Conservation of Endangered Species (LaCONES) in Hyderabad had been at the forefront of such initiatives. LaCONES established techniques for the collection and cryo-preservation of genetic material from wildlife, keeping a genetic resource bank essential for species recovery programs.
Challenges and Future Prospects
Though the creation of the frozen zoo is a towering success, a number of challenges remain:
Rapid Response Requirement: The procurement of viable genetic samples requires rapid response, sometimes within an hour of an animal's death or sickness, to preserve the integrity of the material.
Technological and Logistical Limitations: Cryogenic storage and sample transportation from far-flung areas demand strong infrastructure and coordination.
Ethical Implications: The possibility of de-extinction or species reintroduction provokes ethical arguments regarding human interference in nature.
In the future, the success of the Darjeeling frozen zoo may open the door to similar projects throughout India, supporting conservation efforts across the country. International biobank and research institution collaborations could improve genetic diversity and resource sharing.
Conclusion
India's creation of a frozen zoo at the Darjeeling Zoo is a landmark achievement in wildlife conservation. By maintaining the genetic blueprints of threatened species, this project not only protects biodiversity but also represents the integration of conventional conservation practices with contemporary biotechnology. With challenges to wildlife around the world, such creative strategies are essential in ensuring that future generations inherit a world full of diverse and thriving life forms.
