As a world-renowned conservation area, Danum Valley is home to numerous species of plants and animals, with 340 species of birds, 124 species of mammals, 72 species of reptiles, and 56 species of amphibians. The valley is considered a true biodiversity hotspot, with several rare and endangered species, including the Bornean Orangutan, the Pygmy Elephant, the Clouded Leopard, and the Proboscis Monkey. The forest is also home to over 15,000 species of plants, including the world's tallest tropical tree, and 94% of the plant species in Danum Valley are from the dipterocarp genus, with many of these species being endemic to Borneo.
