10 Rare Siamese Crocodiles Return to Cambodia's Wild

Conservationists just released ten purebred Siamese crocodiles into Cambodia's Srepok River, marking a major milestone for one of the world's rarest reptiles.

The crocodiles, bred in a special facility managed by Cambodia's Forestry Administration and Fauna & Flora International, underwent genetic screening and health checks before their release. Each one carries an acoustic tag so researchers can track how they adapt to their new home in Mondulkiri province's Srepok Wildlife Sanctuary.

The Siamese crocodile sits on the International Union for Conservation of Nature's critically endangered list. Fewer than 1,000 survive in the wild globally, making every single animal precious to the species' future.

Cambodia now hosts one of the largest remaining wild populations. About 300 Siamese crocodiles live across the country's northeastern provinces and the Cardamom Mountains, according to the Ministry of Environment.

WWF Cambodia led the release effort alongside government ministries, local authorities, and Indigenous communities who call the river home. The collaboration took years of scientific research to ensure the crocodiles would thrive in the Srepok's ecosystem.

The Ripple Effect

This isn't just about saving crocodiles. The Srepok River sits in the Eastern Plains Landscape, one of Southeast Asia's most vital biodiversity hotspots.

"By having more breeding pairs in the Srepok River, we are not only helping secure its survival but also strengthening ecosystem health and resilience for biodiversity and communities that depend on these natural resources," said WWF Cambodia Country Director Dipankar Chyau Patnaik. Healthy crocodile populations signal healthy rivers, which means thriving fish populations and clean water for the communities downstream.

The good news gets better. In 2019, researchers confirmed natural hatchings of Siamese crocodiles in the Srepok River, the first sign that earlier conservation efforts were working. These ten new residents should boost breeding pairs and genetic diversity.

The project includes river patrols, habitat protection, and awareness campaigns against illegal fishing. Ministry of Environment spokesperson Khvay Atitya emphasized that Siamese crocodiles pose no danger to people, feeding mainly on fish and avoiding human contact.

The gentle giants of Cambodia's rivers are staging a comeback, one careful release at a time.
