Answer

Introduction

Species conservation is crucial for ecological balance and biodiversity resilience. The recovery of saltwater crocodiles in the Sundarban Biosphere Reserve highlights the effectiveness of statutory frameworks like the Wildlife (Protection) Act, 1972, combined with targeted interventions such as habitat management and species-specific programmes.

Role of Statutory Frameworks and Targeted Conservation Interventions

• Legal Protection through Wildlife (Protection) Act, 1972: Provides blanket protection to species, including saltwater crocodiles, prohibiting hunting and trade.
• Targeted Conservation Projects: Site-specific interventions such as captive breeding, habitat restoration, and release programs help recover vulnerable populations.
  Eg: Bhagabatpur Crocodile Project in West Bengal focused on breeding and release of juveniles.
• Monitoring and Research: Systematic censuses and ecological studies guide policy decisions, helping identify population trends and age structures.
  Eg: Recent surveys indicate improved juvenile survival and demographic diversity.
• Integrated Approach Beyond Charismatic Species: Expands conservation focus to non-megafauna (other than charismatic species like Tiger and Elephant), ensuring ecosystem-level benefits.
  Eg: Protecting crocodiles also sustains mangrove health and food webs in Sundarbans.
• Community Engagement and Awareness: Public communication strategies and local involvement support long-term protection.

Emerging Threats to Species Conservation

• Climate Change and Habitat Alteration: Rising sea levels, salinity, cyclones, and erosion threaten breeding and foraging habitats.
• Fragmentation and Urban Pressure: Human settlements, aquaculture, and infrastructure projects reduce contiguous habitats and corridors.
• Pollution and Resource Exploitation: Contamination of waterways and overfishing disrupt prey availability and aquatic ecosystem balance.
• Invasive Species and Disease: Non-native species and pathogens can alter ecological balance and reduce survival rates of native fauna.
• Reactive vs. Proactive Policies: Existing frameworks often respond after threats emerge; anticipatory measures like climate refugia mapping and assisted breeding are limited.

Measures to Protect Species

• Proactive, Well-Funded Conservation Plans: Develop anticipatory action plans, including habitat restoration, captive breeding, and release programs, with sufficient financial and human resources.
• Climate-Resilient Strategies: Identify climate refugia, incorporate sea-level rise and salinity impacts, and enable assisted migration or breeding to adapt to changing environments.
• Strengthen Legal Enforcement: Ensure stricter implementation of Wildlife (Protection) Act, 1972, along with monitoring against poaching, illegal trade, and habitat encroachment.
• Community Participation and Awareness: Engage local communities in conservation efforts, provide alternative livelihoods, and promote awareness to reduce human-wildlife conflicts.
• Ecosystem-Based and Integrated Approach: Protect entire ecosystems, including mangroves and freshwater habitats, rather than focusing solely on a single species, ensuring sustainable biodiversity management.

Conclusion

The recovery demonstrates that focused policy support and scientific interventions can restore wildlife populations. Addressing emerging threats like climate change, habitat loss, and pollution through proactive ecosystem management and community participation is essential for long-term species protection.
