    • Fragmentation of habitats reduces genetic diversity and increases vulnerability.
  2. Hunting and Poaching

    • Hunted for meat, trophies, and traditional medicine.
  3. Competition with Livestock

    • Overgrazing by domestic animals reduces available food.
  4. Predation and Disease

    • Predation by large carnivores and diseases transmitted by livestock.
  5. Climate Change

    • Alters habitat conditions, leading to reduced food availability and increased stress.

Conclusion

The Sambar Deer is not just a majestic animal but a vital component of India’s forest ecosystems. Protecting this species is crucial for maintaining biodiversity and ecological balance.
