Quick answer
IUCN lists Javan rhinos (Rhinoceros sondaicus) as Critically Endangered (2020; trend Stable). One remaining population: Ujung Kulon National Park, Java. Treat on the order of 50–80 animals as planning — WARN copy says about 50 — not a weekly census. Figures checked 13 August 2026.
Are Javan rhinos Critically Endangered?
Yes. IUCN 2020: Critically Endangered, trend Stable. “Listed in our guides as Critically Endangered” without Ujung Kulon and the ~50–80 planning band was the thin version of this page. Stable is not an African white-rhino story.
What is driving the risk?
Historic poaching for horn, a single tiny population, disease and tsunami risk on a Krakatau-facing peninsula, and invasive Arenga palm crowding out browse. This is not a farms-and-suburbs generic. Ranking those threats stays inside one park.
Is a Stable trend an all-clear?
No. Stable on one peninsula can still vanish in a disease pulse or a tsunami. A second population has been discussed for years because one park is not a safety net. Camera-trap births are not a continent-scale rebound.
What actually helps?
Funded protection, palm clearing that restores browse, and honest talk about a second site. WARN’s rhino appeal funds partner-led anti-poaching and rescue — not Ujung Kulon camps.
How rare is “about 50”?
Rare enough that one park is the species. Vietnam’s last Javan rhino was poached in 2010. Treat WARN’s “about 50” and the wider ~50–80 band as campaign and planning figures, not a live dashboard.
Why is a second population so slow?
Habitat needs, tsunami risk, and Arenga palm that smothers food plants. Anti-poaching success does not cancel those. A forest browser cannot be parked on an African grassland as a backup.

Javan Rhino FAQs
Are Javan rhinos endangered?
IUCN lists the Javan rhino (Rhinoceros sondaicus) as Critically Endangered (2020; population trend Stable). One remaining population survives in Ujung Kulon National Park, Java. Treat on the order of 50–80 animals as a campaign and planning range — WARN copy says about 50 — not a weekly census. Not a white rhino. Figures checked 13 August 2026.
How many Javan rhinos are left?
A single park on western Java holds the entire species. Campaign copy often says about 50; planning figures commonly sit in a ~50–80 band. That is not a camera-trap count refreshed each week. The Vietnam remnant was poached out in 2010. A Kruger white-rhino density is not Ujung Kulon.
Are they the same as white or African rhinos?
No. Javan rhinos are Asian forest browsers with one horn. White rhinos are African grazers; black rhinos are African hooked-lip browsers. Mixing them produces the false story that a southern African rebound protects Java. Horn is keratin in all of them; this map is still one park.
What actually helps Javan rhinos?
Guard Ujung Kulon, cut Arenga palm that smothers browse, and keep disease and tsunami risk on the planning table. World Animal Rescue Network’s rhino appeal funds partner-led protection. WARN does not run Ujung Kulon.
