The only viable population of Javan rhinos in the world
This was the only known population, until less than 10 rhinos were discovered clinging to survival in Vietnam's Cat Tien National Park in the 1980s. Thus, Ujung Kulon is absolutely critical for the survival of the Javan rhino as well as numerous other endangered species, many of which are endemic - occurring nowhere else but the island of Java.
Java: densely populated and deforested
The island of Java is home to over 100 million people, making it one of the most densely populated areas on our planet. Not surprisingly, almost all of Java's forests have been destroyed, with a few remaining on steep mountain slopes and infertile areas. Indeed, the last tigers in Java died out in the 1980s.
A natural haven for the rhino
Ujung Kulon National Park contains a unique remnant of lowland Javan rainforest separated from inhabited areas by a volcano and narrow isthmus.
Ujung Kulon is home to numerous endangered species, providing a stronghold for species like the Javan rhinoceros, Javan gibbon, and banteng, a species of wild cattle.
WWF's early days in Ujung Kulon
WWF first began supporting conservation work in Ujung Kulon in 1964, by providing equipment to Indonesian park authorities and funding scientific research. In 1967, an estimated 21-28 Javan rhinos lived in Ujung Kulon, but anti-poaching patrols and habitat protection allowed the population to grow to 45-54 animals by 1976.
