Sixty baby Siamese crocodiles have hatched in Cambodia’s Cardamom Mountains — the largest single hatching of the critically endangered species recorded anywhere in this century. Conservationists are calling it a “real sign of hope” after more than two decades of painstaking work to pull the reptile back from the edge of extinction.
At a glance
- Siamese crocodile hatching: Sixty hatchlings emerged from five nests discovered in May 2025 C.E., with the births confirmed at the end of June — a century-record for the species.
- Wild breeding: The nests were found in an area where no crocodiles had been released, suggesting the population is now reproducing on its own in natural habitat.
- Captive release programme: Since 2012 C.E., conservation partners have released 196 Siamese crocodiles into suitable habitats across the Cardamom Mountains.
Why this hatching matters
Siamese crocodiles were once found across much of Southeast Asia. Decades of hunting and habitat loss reduced them to a population so small that, by the late twentieth century, many scientists believed they had vanished entirely from the wild.
They were rediscovered in Cambodia in 2000 C.E. Today, roughly 400 individuals are estimated to survive worldwide, and the vast majority live in Cambodia. With numbers that low, 60 new hatchlings represent a significant fraction of the total population.
“The hatching of 60 new crocodiles is a tremendous boost,” said Pablo Sinovas, who leads the Cambodia programme for conservation group Fauna & Flora. He described it as hugely encouraging for the collaborative model the programme has built over more than 20 years.
A partnership built on trust
The recovery effort is not the work of a single organisation. Fauna & Flora has partnered with local NGOs, the Cambodian government, and — critically — communities living in and around the Cardamom Mountains.
Local community wardens run regular patrols through the mountains to protect released crocodiles from poaching and disturbance. When the five nests were discovered in May 2025 C.E., the conservation team quickly deployed people to guard them around the clock until every egg had hatched.
That community-centred approach echoes what the IUCN Crocodile Specialist Group has long identified as essential for freshwater crocodilian recovery: local stewardship, not just scientific intervention.
What the wild nests signal
Perhaps the most significant detail in this story is where the nests were found. The site had not received any released animals from the captive-breeding programme. That means the crocodiles nesting there were almost certainly wild-born individuals — or the offspring of previously released animals that had established themselves and begun breeding without human help.
That distinction matters enormously. A species that is breeding naturally across new territory is doing something fundamentally different from one that survives only through continuous human intervention. It is beginning to recover.
The Siamese crocodile is a freshwater species, olive-green in colour with a distinctive bony crest at the back of its skull. Adults can reach up to three metres in length. They favour slow-moving rivers, lakes, and wetlands — habitats that the Cardamom Mountains of southwestern Cambodia still provide in relative abundance, partly because the region has been the focus of sustained conservation investment.
The road still ahead
Sixty hatchlings is cause for real optimism, but the Siamese crocodile remains critically endangered. A global wild population of around 400 individuals is still dangerously low, and habitat pressures across Southeast Asia have not disappeared. Continued funding, sustained community engagement, and government protection of wetland habitats will all be needed to secure what has been built.
The programme has also shown that recovery is a long game. Fauna & Flora began this work in the early 2000s C.E., and it took more than two decades to reach a hatching of this scale. Patience, consistency, and local trust were as important as any scientific technique.
For a species once feared lost, a morning in June 2025 C.E. when 60 small crocodiles pushed out of their shells in the Cambodian mountains counts as something worth marking.
