Hollong: India’s Tallest Native Rainforest Tree in Assam

Hollong, Assam’s state tree, is one of India’s tallest native rainforest species, growing up to 50 meters across the Northeast. It thrives in areas with nearly 3,000 mm of annual rainfall. Its deep roots stabilize it in waterlogged soils, while large leaves shed rainwater to prevent fungal damage. Hollong dominates tropical evergreen forests like Hollongapar Gibbon Sanctuary and Kaziranga, shaping cooler forest microclimates.
