According to research teams working in Phuoc Binh National Park, five survey routes were established across key habitats beginning in late 2023, using integrated methods that combined biological trace analysis, direct observation, and continuous camera trap systems over multiple months. Among the most important discoveries was clear evidence of gaur activity across two major survey zones, Gia Nhong and Da Den. Scientists identified footprints, dung, feeding signs, and photographic records indicating the presence of approximately 13 to 17 individual gaur in these forest landscapes.

This population estimate is particularly meaningful because gaur are highly sensitive to habitat degradation and human disturbance. Their presence in relatively stable numbers suggests that parts of southern Khanh Hoa continue to provide ecologically suitable environments capable of supporting large herbivores. In Gia Nhong alone, researchers identified two separate herds—one estimated at four to six individuals, including at least one juvenile, and another group of three to four adults. In Da Den, six to seven mature gaur were recorded. These observations indicate not just temporary movement, but potentially stable habitat use and breeding activity.

The gaur were primarily found in coniferous forest habitats on sloped terrain, interspersed with grasslands and evergreen forests—an ecological mosaic well suited to the species’ feeding and movement patterns. Such habitat diversity is one of the defining strengths of Phuoc Binh, which lies within a unique ecological transition zone between the Langbiang Plateau’s montane evergreen forests and the lowland ecosystems of South Central Vietnam.

Beyond gaur, the survey also documented an extraordinary range of other high-conservation-value species, including black-shanked douc langurs, yellow-cheeked gibbons, Sunda pangolins, large flying squirrels, serow, civets, deer, and numerous birds, reptiles, and amphibians listed in both Vietnam’s Red Data Book and the IUCN Red List. Particularly notable was the observation of eight troops of black-shanked douc langurs totaling an estimated 149 to 180 individuals—another strong sign of ecological health.

For conservation scientists, these findings are crucial. Reliable biodiversity data is the foundation of effective management, allowing authorities to design more precise habitat protection plans, anti-poaching strategies, species monitoring systems, and ecological corridor preservation. In an era of increasing pressure from climate change, habitat fragmentation, and human encroachment, such evidence-based conservation is essential.

Phuoc Binh’s approximately 25,000-hectare forest system is therefore more than a protected area—it is a living biological archive and strategic refuge for species survival. The discovery of substantial gaur populations strengthens the argument for intensified protection, deeper scientific investment, and stronger regional conservation planning.

Ultimately, these discoveries offer rare optimism. At a time when biodiversity decline dominates global conservation concerns, southern Khanh Hoa’s forests demonstrate that with protection, ecological integrity can endure. Every gaur footprint, every camera-trapped image, and every recorded primate troop is a reminder that science-led conservation remains one of the most powerful tools for securing the future of Vietnam’s natural heritage.
