Context
Assam recently witnessed the world's first release of captive-bred slender-billed vultures into the wild at the Jatayu Soft Release Centre in Kaziranga National Park and Tiger Reserve. This milestone, achieved by the (BNHS) and the Assam Forest Department, marks a critical step in the conservation of a species whose population in India plummeted by 99% due to toxic veterinary drugs and pesticide poisoning.
UPSC Perspectives
Environmental
This release is a landmark in ex-situ conservation (protecting an endangered species outside its natural habitat, like in breeding centres) transitioning back to in-situ conservation (protecting them in their natural habitat). The Slender-billed Vulture (Gyps tenuirostris) is classified as Critically Endangered on the and is protected under Schedule I of the . Vultures are keystone species and obligate scavengers; they play a vital role in the ecosystem by disposing of carcasses, thereby preventing the spread of zoonotic diseases like anthrax and rabies. The decline in the Gyps vulture population in India, often referred to as the 'Vulture Crisis', was primarily driven by the use of Diclofenac, a non-steroidal anti-inflammatory drug (NSAID) used in livestock. When vultures feed on carcasses of cattle treated with Diclofenac, they suffer from visceral gout and kidney failure, leading to mass mortality. UPSC frequently asks about the ecological roles of specific species and the causes of their decline, making the distinction between different vulture species and their conservation status crucial.
Governance
The conservation effort highlights the role of regulatory mechanisms and collaborative governance in wildlife protection. The (MoEFCC) launched the Action Plan for Vulture Conservation in India (2020-2025), emphasizing the establishment of Vulture Conservation Breeding Centres (VCBCs) and Vulture Safe Zones. The government's ban on veterinary use of specific NSAIDs—diclofenac, aceclofenac, ketoprofen, and nimesulide—demonstrates a crucial regulatory intervention to mitigate the primary threat. However, the article notes that secondary poisoning (where vultures die after consuming carcasses laced with pesticides intended to kill feral dogs) remains a significant challenge. This points to a gap in enforcement at the grassroots level and the need for stronger inter-departmental coordination (between forest, agriculture, and veterinary departments) to control pesticide misuse. From a UPSC perspective, understanding the effectiveness of the Action Plan and the challenges of implementing bans on harmful chemicals is key to analyzing environmental governance.
Geographical
The location of the release, the in Assam, is geographically significant. Kaziranga, a , is primarily known for the Great One-horned Rhinoceros, but its diverse ecosystem of wetlands, grasslands, and semi-evergreen forests makes it an ideal habitat for vultures. The park acts as a sanctuary where the newly released captive-bred vultures can integrate with wild populations. The use of a 'Soft Release Centre' is a strategic geographical intervention; it allows the birds to acclimatize to the local environment, learn foraging skills, and interact with wild vultures before full independence. Candidates should note the geographical distribution of vulture species in India and the specific protected areas involved in their conservation, as mapping questions related to national parks and critically endangered species habitats are common in the Prelims.
