Western Ghats

Also known as: Sahyadri, Sahyadri Mountains

A 1,600 km mountain chain along India's western coast, older than the Himalayas, and one of the world's eight 'hottest hotspots' of biological diversity (Myers et al. 2000). Home to over 7,400 plant species, 1,800 of them endemic, and to the source watersheds of every major peninsular Indian river. The forests of the Western Ghats produce most of India's wild-harvested black pepper, cardamom, and cinnamon, and the hills are dotted with spice gardens, coffee estates, and Indigenous Adivasi communities (Toda, Kurumba, Irula, Kani, Soliga) whose traditional knowledge underlies the spice-and-medicine economy.

Why this entry

The Western Ghats anchor future listings of South Indian spice cooperatives, Adivasi forest-product collectives, sustainable cardamom and coffee estates, and Ayurvedic medicinal-plant cultivators. The region’s combination of extreme biodiversity, traditional spice-economy depth, and active Indigenous food-sovereignty work makes it a high-leverage bioregion for aligned commerce in South Asia.

What’s distinctive

The mountains run as a near-continuous wall along the Arabian Sea coast, intercepting the southwest monsoon and creating an extreme west-to-east rainfall gradient — the windward (western) slopes can receive over 6,000 mm of rain per year, while the leeward (eastern) plains lie in a sharp rain shadow. This gradient generates a stunning compression of forest types — evergreen rainforest at the wet base, shola montane grasslands and stunted forest patches at high elevation, dry deciduous forest on the leeward eastern flank.

Endemism is striking — over 70% of the amphibians are endemic, including the recently-discovered purple frog (Nasikabatrachus sahyadrensis), a “living fossil” with no close living relatives. Strobilanthes kunthiana — neelakurinji — flowers in mass blooms once every 12 years, painting the high Ghats blue in a phenomenon central to Tamil and Malayalam cultural identity.

Forty UNESCO-listed serial sites along the chain protect the most ecologically significant forest fragments.

Indigenous and contemporary

Soliga, Kurumba, Irula, Toda, Kadar, Malayali, Paniya, Adiyan, Kani, and many other Adivasi peoples are the Indigenous communities of the Ghats. The Toda dairy-pastoral culture of the Nilgiri Hills and the Kani knowledge that led to the Trichopus zeylanicus (jeevani) benefit-sharing model are both significant. Smallholder coffee, cardamom, and pepper estates intersperse with forest reserves; the Karnataka coffee belt and the Idukki cardamom belt are particularly notable.

demonstrated by

  • Biodiversity hotspot the Western Ghats and Sri Lanka are jointly designated as one of the 36 hotspots
  • Endemism the Western Ghats have ~60% amphibian endemism and high endemism across most taxonomic groups
  • Monsoon the southwest monsoon's interception by the Western Ghats produces the wet windward / dry leeward rainfall gradient
  • Rain shadow the wet windward / dry leeward gradient across the Ghats is one of the most dramatic short-distance rainfall gradients on Earth

Practical

demonstrated by

  • Vertical economy wet windward base, *shola*-grassland highland, dry leeward eastern slope — one community can work all three on a single mountain

  • Soliga an Adivasi forest community of the southern Western Ghats
  • Toda the Indigenous dairy-pastoral people of the Nilgiri plateau in the southern Western Ghats
