Mangrove ecosystem and conservation of the Java rhinoceros

Project MERCI – Indonesia

On deployment

The western tip of the island of Java in Indonesia is home to the Ujung Kulon National Park (UKNP), which faces a high risk of volcanic eruptions, earthquakes and tsunamis, as was the case in 2018. This vulnerability to natural disasters is increased by human density and activity.

Ujung Kulon National Park (UKNP), on the island of Java in Indonesia, is increasingly vulnerable to volcanic eruptions, earthquakes, tsunamis and other natural disasters. This vulnerability is increased by human density and activity, particularly due to the development of tourist infrastructures. Mangroves have suffered massive degradation and this situation now threatens the livelihoods of local communities.

Within the park, part of the Javan rhino’s habitat has disappeared, leading to the decline of this emblematic animal. The latest census in 2020 indicates that only 74 individuals of the Javan rhinoceros remain, making it the most critically endangered large mammal on the planet.


To contribute to the restoration of the mangrove ecosystems of the Ujung Kulon National Park and its surrounding area, as well as the conservation of its wildlife, in particular by preserving the habitat of the Javan rhinoceros.
