Biodiversity Richness in Indian States

Biodiversity richness refers to the variety of life forms within a specific ecosystem or region. It encompasses species diversity, genetic diversity, and ecosystem diversity. Biodiversity is crucial for ecosystem services, cultural significance, economic value, and resilience against environmental changes. India is one of the 17 megadiverse countries, hosting approximately 7-8% of the world’s recorded species.

Geographic and Ecological Context

India features a range of diverse ecosystems. These ecosystems span from the towering Himalayas to expansive coastal regions, arid deserts, and lush forests. The major biogeographic zones of India include:

  • Himalayan Region
  • Indo-Gangetic Plains
  • Desert Region (Thar Desert)
  • Western Ghats
  • Eastern Ghats
  • Coastal Regions
  • North East India
  • Islands (Andaman and Nicobar, Lakshadweep)

Biodiversity Hotspots in India

Biodiversity hotspots are regions with biodiversity that face threats from human activities. Notable hotspots in India include:

  • Western Ghats and Sri Lanka
  • Indo-Burma
