Explanation: The Western Ghats are one of the world’s major biodiversity hotspots with a high degree of endemism. The newly discovered Humboldtia nairiana is restricted to a very small area in the Agasthyamala Biosphere Reserve and has fewer than 10 known mature trees. Such narrowly distributed endemic species are highly vulnerable to habitat loss, climate change, and ecological disturbances. Therefore, both in-situ conservation (protecting natural habitats) and ex-situ conservation (preserving species outside their habitat, such as in botanical gardens) are essential for long-term survival.
