New Species Discovered in Cambodia’s Karst Caves, Study Finds

PHNOM PENH, March 23, 2026 (KPT) — A new biodiversity survey has uncovered a wide range of previously unknown species in Cambodia’s karst cave systems, underscoring the ecological importance of these fragile landscapes.​

The study, published on March 23, explored more than 60 caves across ten limestone hills in Battambang province. Researchers described the area as a “treasure trove” of wildlife, including species found nowhere else on Earth.

Led by conservation group Fauna & Flora in collaboration with Cambodia’s Ministry of Environment, the survey identified several species new to science — among them three geckos, two micro-snails and two millipedes already formally described. Additional species, including three more geckos and a pit viper, are still under review.

Scientists also confirmed the presence of globally threatened wildlife such as the Sunda pangolin, Indochinese silvered langur, long-tailed macaque and green peafowl.

They said the findings highlight the urgency of protecting karst habitats, which are increasingly threatened by quarrying, illegal logging, hunting, wildfires and poorly managed tourism.

Khvay Atitya, spokesperson for the Ministry of Environment, said the discoveries demonstrate Cambodia’s “outstanding natural richness” and reaffirm the government’s commitment to balancing development with conservation.

Fauna & Flora said it is working with local partners to promote sustainable management of cave ecosystems, including guidelines to protect biodiversity while supporting responsible tourism and local livelihoods.

The survey, supported by the EU-funded BCOMING project, used camera traps and field studies to document bats, reptiles, amphibians, invertebrates and mammals, with experts warning that many species may remain undiscovered and at risk of extinction without stronger protection.
