Ujung Kulon National Park, located in Banten Province on the extreme south-west tip of the highly populated island of Java, has the best and most extensive lowland forest remaining on the island. The property, including the Ujung Kulon peninsula and several offshore islands retains its natural beauty and possesses a very diverse flora and fauna, demonstrating on-going evolution of geological processes since the Krakatau eruption in 1883. The Krakatau volcano as part of the formation of the property, is the most well known and studied of all modern volcanic eruptions, due primarily to the devastating effects (36,000 people killed) registered throughout the northern hemisphere. The property is globally significant as the last and most important natural habitat of the critically endangered, endemic, single-horned Javan Rhinoceros (Rhinoceros sondaicus) along with several other species of endangered plants and animals. Ujung Kulon is believed to sustain the last viable natural population of this species, estimated at approximately 60 individuals. It is not known how this compares to historical densities, but is a critically low figure from the point of view of species survival and viable genetic diversity.Other notable mammals in the property include carnivores, such as leopard, wild dog (dhole), leopard cat, fishing cat, Javan mongoose and several species of civets. It is also home to three endemic primate species; the Javan gibbon, Javan leaf monkey and silvered leaf monkey. Over 270 species of birds have been recorded and terrestrial reptiles and amphibians include two species of python, two crocodile species and numerous frogs and toads.
