Hunted for their horn - a highly prized commodity in traditional Asian medicines - and decimated by the destruction of their lowland rainforest habitat, many Asian rhinos now hover on the brink of extinction. As one of WWF's flagship species, the Asian Rhino is considered an essential species within the complex ecosystems it inhabits. The loss of the rhino would damage many other animals and plants that rely on it to uproot old vegetation, overturn soil, and expose new growth and food sources. The Asian Rhino are amongst the world's most endangered large land mammals. In 2005, less than 3,000 are known to exist in the wild with one species numbering less than a 100 individuals.
