    Apart from Western Ghats, two national parks in India – Assam’s Manas national park and West Bengal’s Sundarbans national park – have also been categorised as being of “significant concern”.

    • IUCN World Heritage Outlook assesses the conservation prospects of all World Heritage sites inscribed for their natural values.
      • The outlook categorizes sites in four categories - Good, Good with some concerns, Significant Concern, and Critical. 
      • Significant concern outlook means that site’s values and underlying attributes are threatened by several current and/or potential threats, requiring additional conservation measures. 

    About Western Ghats

    • Length: About 1,600 km long, they are a chain of mountains older than the Himalayas and running parallel to India’s western coast.
    • Spread across six states: Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu.
    • Ecological Significance: A UNESCO world heritage site and one of 36 biodiversity hotspots on Earth.
      • Recognized as one of the world’s eight ‘hottest hotspots’ being habitat to some 325 globally threatened (listed in IUCN’s Red List) species including Nilgiri Tahr. 
      • Best representative of non-equatorial tropical evergreen forests.
      • Influence the Indian monsoon weather pattern, acts as key barrier intercepting rain-laden monsoon winds coming from southwest, and moderates tropical climate of the region.

    Threats to Western Ghats

    • Infrastructure Development: Hundreds of hydropower projects including proposed Sillahalla Pumped Storage Hydroelectric project in the Nilgiris.
    • Land Use Conversion: Large part of range converted to agricultural land for tea, coffee, rubber and oil palm or cleared for livestock grazing, reservoirs and road.
    • Human-Wildlife Conflict:  Dense population in several parts and expansion of agriculture leads to increased human-wildlife conflict.
    • Climate change: Forcing species like Nilgiri flycatcher to move from warmer lowlands to cooler higher areas.
    • Invasive Alien Species: Such as eucalyptus and acacia colonising natural forests.
