根据《2026年犀牛现状报告》，印度尼西亚的苏门答腊犀牛和爪哇犀牛正面临灭绝危机。1苏门答腊犀牛种群从1998年的约300头锐减至今日不足50头，全部分布在印度尼西亚。1爪哇犀牛数量同样严峻，约50头个体仅存于爪哇岛的乌戎库隆国家公园内。1
两个物种面临的主要威胁源于偷猎、栖息地丧失和全球犀牛角需求的增加。1在2019年至2023年间，偷猎者杀死了多达26头爪哇犀牛。1苏门答腊犀牛的繁殖困难加剧了种群恢复的挑战——其妊娠期约16个月，每胎仅生一只，且隔数年才生育下一胎。1即便有保护措施，效果也极为有限，2012年至2023年间，苏门答腊犀牛保护区内仅出生5只小犀牛。1
保护机构正通过多种方式开展救援工作，包括建立保护区、人工饲养繁殖和反偷猎措施。1位于苏门答腊岛韦方坎巴斯国家公园的苏门答腊犀牛保护区成立于1996年，目前饲养有10头犀牛。1全球对犀牛角的需求不断增加，特别是在中国和越南，犀牛角既被用于传统医学，也被视为财富和地位的象征。1爪哇犀牛的境况尤其危急，因其所有个体仅生活在单一地点，易遭自然灾害完全灭绝。1
Indonesia's Sumatran and Javan rhinos are teetering on the edge of extinction, with populations far more critically endangered than their African counterparts. According to the 2026 State of the Rhino Report, fewer than 50 Sumatran rhinos remain in the wild, down from approximately 300 in 1998, while the Javan rhino population stands at around 50 individuals 1. Both species are found exclusively in Indonesia, with all Javan rhinos confined to Ujung Kulon National Park on Java Island, making them exceptionally vulnerable to catastrophic loss 1.
The breeding challenges facing these species compound their dire situation. Sumatran rhinos have a gestation period of approximately 16 months and give birth to only one calf at a time, with several years elapsing between successive births 1. This reproductive limitation is exacerbated by the scattered distribution of the surviving population, which hinders natural breeding 1. Between 2012 and 2023, only five calves were born in the Sumatran rhino sanctuary 1. A protected facility was established in 1996 at Way Kambas National Park on Sumatra, currently housing 10 rhinos 1. Poaching remains a severe threat; between 2019 and 2023, poachers killed as many as 26 Javan rhinos 1.
The escalating global demand for rhino horn, particularly in China and Vietnam, where it is used both in traditional medicine and as a status symbol, continues to drive the crisis 1. Without sustained conservation intervention including habitat protection, anti-poaching measures, and breeding programs, both Indonesian rhino species face the prospect of extinction.
