Projects: Ujung Kulon

WWF Achievements

  • Camera-trapping and photo-array analysis suggests that the rhino population may indeed be static at 50-60 animals.
  • No Javan rhinos have been poached in Ujung Kulon National Park this year, which now has anti-poaching patrols within the park as well as teams using boats around the peninsula. Ujung Kulon patrol effort stands at 106.77 kilometers and 16.97 forest patrol days per unit per month.
  • Local communities are benefiting from ecotourism in Ujung Kulon, a jewel in Indonesia's protected areas system.

Future Objectives


  • WWF will continue to support anti-poaching patrols to ensure the protection of the park's rhinos, and to prevent illegal bird-trapping and dynamite fishing that damages the park's coral reefs.
  • Further photo-trapping and a statistical overview of project design methods should clarify the significance of current population estimates using the photo-trap modality. In addition, if sufficient numbers of samples can be collected, fecal DNA work may allow for a second approach to censusing via mark-recapture modelling.
  • Rhino ecology research will continue to determine if banteng are limiting rhino population growth by competing with rhinos for food. If the findings indicate that a growing banteng population is curbing potential recovery of the Javan rhino population, then the authorities will need to consider decreasing the number of wild cattle in the park.
  • Decreasing banteng numbers could involve moving them to other conservation areas, including Baruran, East Java, and/or Pangandaran and Cikapuh in West Java once feasibility studies indicate this would be acceptable. Banteng are also endangered and relocating some out of Ujung Kulon could benefit the species by establishing and strengthening other populations elsewhere.
  • Eventually, the feasibility of translocating rhinos to establish a new Javan rhino population elsewhere will be assessed (once Ujung Kulon's population is large enough and a suitable and secure site for a new population can be identified). This idea may be decades from becoming a reality, but will hopefully be possible some day.

Conservation Partners: To save Ujung Kulon National Park's Javan rhinos, WWF collaborates with many governmental and non-governmental organizations. These include the U.S. Fish & Wildlife Service (USFWS) and the International Rhino Foundation (IRF).
