Asiatic Lion Conservation in India: Need for a Second Population Explained

GS III: Conservation, Environmental Pollution and Degradation, Environmental Impact Assessment, Biodiversity

Context: India has achieved remarkable success in conserving the Asiatic lion population, with their numbers increasing significantly over the past century. 

• However, despite this conservation achievement, nearly the entire wild population remains confined to the Gir landscape in Gujarat, making the species vulnerable to disease outbreaks, natural disasters, and other catastrophic events.
• Conservation experts and the Supreme Court have repeatedly emphasized the need to establish a geographically separate second population of Asiatic lions. 
  • A second habitat is considered essential for ensuring the long-term survival of the species by reducing the risks associated with maintaining a single isolated population.

Background

• Historically, Asiatic lions ranged from the Middle East to northern and western India.
• Excessive hunting and habitat loss drastically reduced their numbers during the early twentieth century.
• Conservation efforts initiated by the Nawab of Junagadh helped prevent their extinction.
• Today, the entire wild population survives primarily in the Gir landscape of Gujarat, making it one of the world’s greatest conservation success stories.

Why is a Second Home Necessary?

• Single Population Risk: The entire wild population is concentrated in one geographical region.
  • A single disease outbreak, forest fire, cyclone, drought, or any other natural disaster could threaten the survival of the entire species.
• Disease Vulnerability: In 2018, an outbreak of Canine Distemper Virus (CDV) caused the death of several Asiatic lions in Gir.
  • The incident demonstrated the danger of maintaining a dense population in a single habitat.
• Low Genetic Diversity: Continuous breeding within a geographically isolated population reduces genetic diversity.
  • Lower genetic variation increases susceptibility to diseases and reduces the adaptive capacity of the species.
• Bottleneck Effect: A population bottleneck occurs when a species survives through a very small population.
  • Reduced genetic diversity resulting from the bottleneck increases the long-term risk of extinction.

Supreme Court’s Directions

• In 2013, the Supreme Court directed that a group of Asiatic lions should be translocated from Gir National Park to Kuno National Park.
• The Court held that wildlife conservation must be guided by ecological principles rather than political considerations.
• It further observed that Asiatic lions constitute the national heritage of India and cannot be treated as the exclusive property of any one State.

Why Has the Project Been Delayed?

Opposition from Gujarat

• Gujarat has opposed the relocation of lions outside the State.
• It argues that Gir has successfully conserved the species and questions the suitability of Kuno National Park as an alternative habitat.

Policy Deadlock

• The issue has resulted in a prolonged conflict between:
  • Scientific recommendations,
  • Judicial directions, and
  • State-level political considerations.

Project Lion

• Launched in 2020, Project Lion aims to:
  • Identify additional suitable habitats for Asiatic lions.
  • Strengthen habitat management.
  • Improve disease surveillance.
  • Enhance long-term conservation planning.

Why is Barda Wildlife Sanctuary Not a Complete Solution?

• Gujarat proposed Barda Wildlife Sanctuary as an alternative habitat.
• However, experts argue that Barda is located too close to Gir.
• Consequently, a disease outbreak or natural disaster could affect both populations simultaneously, defeating the objective of risk diversification

Concept: Metapopulation

A metapopulation is a network of geographically separated populations of the same species that occupy different habitats while maintaining limited interaction among them.

Benefits

• Reduces extinction risk.
• Prevents complete loss due to localized disasters.
• Improves long-term genetic diversity.
• Enhances ecological resilience.
• Facilitates species recovery after local population decline.
