Bandung, Indonesia Sentinel — Indonesia is home for two of the world’s most endangered rhino species, the Sumatran rhino (Dicerorhinus sumatrensis) and the Javan rhino (Rhinoceros sondaicus). Both Indonesian rhinos species are classified as critically endangered, face a daunting battle against extinction due to habitat loss, poaching, and the challenges of maintaining viable populations. Conservation efforts are underway, but the path to recovery is fraught with challenges.
The Sumatran Rhino (Dicerorhinus sumatrensis)
The Sumatran rhino, the smallest and hairiest of all rhino species, it is the last surviving species of the same lineage as the extinct woolly rhinoceros. Once widespread across Southeast Asia, today its conservation status labeled as critically endangered. According to IUCN estimation on 2023, fewer than 80 Sumatran rhinos remain, scattered in isolated pockets across the islands of Sumatra and Borneo.
Sumatran Rhino Sanctuary have been established at Way Kambas National Park in Lampung province of Southern Sumatra, focusing on breeding and scientific research to help repopulate the species.
Conservationists are racing against time to save the species, with the primary threat being habitat destruction. As Indonesia’s rapidly expanding palm oil plantations and agricultural development, it have drastically reduced the rhino’s natural rainforest habitat. The species’ fragmented population also poses significant challenges for breeding, making it difficult for individuals to find mates, further jeopardizing their survival.
The Javan Rhino (Rhinoceros sondaicus)
Equally as threatened, the Javan rhino is now considered one of the rarest large mammals on the planet. Once spread across much of Southeast Asia, the Javan rhino is now confined to a single location, Ujung Kulon National Park on the western tip of Java, Indonesia. With only about 76 individuals remaining based on 2023, this rhino’s future hinges entirely on the conservation efforts within this protected park.
The Javan rhino is less affected by poaching, as its horn is not as highly prized. However, habitat loss remains a critical issue, with human encroachment and agricultural development threatening the integrity of Ujung Kulon. The rhino also faces another significant threat which is natural disasters. Ujung Kulon lies in a region vulnerable to volcanic eruptions and tsunamis, which could have catastrophic consequences for the remaining population.
Conservation Status and Population Decline
Indonesian Rhinos, both the Sumatran and Javan are classified as critically endangered by the International Union for Conservation of Nature (IUCN), meaning they face an extremely high risk of extinction in the wild. The primary reasons for their declining populations are habitat destruction and poaching.

For the Sumatran rhino, illegal poaching driven by demand for rhino horn, particularly in China and Vietnam, has historically been a significant factor in their decline. Although poaching has been curbed somewhat in recent years, habitat fragmentation and the inability to find mates are now the main challenges.
In contrast, the Javan rhino’s primary threat is its vulnerability to natural disasters and the lack of genetic diversity within its small population. The species’ population is relatively stable, but with such a limited range, any disaster could wipe out the entire species.
A Future of Indonesian Rhinos
Recently in 2024, a new individual of the Javan rhinoceros was discovered in Ujung Kulon National Park, raising hopes on the survival of this endemic creatures. Despite ongoing conservation efforts, Indonesian Rhinos population remain perilously low. The Indonesian government, in partnership with international conservation organizations, has intensified efforts to protect these species, expanding protected areas, and implementing captive breeding programs.
However, without increased public awareness and continued international support, both the Sumatran and Javan rhinos could be lost forever. The survival of these ancient animals will require a sustained, collective effort to combat habitat destruction, strengthen conservation initiatives, and ensure these majestic creatures continue to roam Indonesia’s forests for generations to come.
