Langkawi’s two main archipelago of 99 islands comprises 477 sq km of land area. Langkawi’s two main terrestrial habitats harbouring biological diversity are inland forests and mangrove forests. The latter comprises one of the richest and most extensive mangrove forest systems in Southeast Asia, with 55 mangrove species, representing nearly half of the world’s total. Here can also be found a species of cycad, Cycas circinalis, which is one of the oldest ‘living fossils’ in the world, dating back to at least the Jurassic, and perhaps as far back as the Triassic.
