Around 280 camera traps have been deployed across the park. Data collected from late 2025 to mid-March 2026 recorded about 30 wildlife species within the forest.

Among them, clear images of the hornbill and otter, both classified as rare and endangered under Group IB protection, were obtained. The animals appeared healthy and active beneath the forest canopy.

“Rangers had previously observed signs or occasional sightings of these species, but this is the first time camera traps have captured clear images of both,” Thuy said.

The hornbill is a tree-dwelling bird that can weigh up to 3 kilogrammes as an adult. Otters, prized for their fur, have been heavily hunted and face a high risk of extinction in the wild.

The camera traps also recorded other species, including monkeys, gibbons, douc langurs, pheasants, muntjacs, wild cats and various reptiles, reflecting the park’s biodiversity.

Covering more than 56,000 hectares, Chu Mom Ray National Park is home to around 1,000 animal species, including 112 classified as rare and endangered under Vietnamese and international conservation lists.
