The dhole (Cuon alpinus) plays an important ecological role as a predator capable of influencing prey populations and maintaining trophic balance in protected ecosystems. This study aimed to analyze predator–prey interaction patterns and evaluate their implications for dhole population dynamics in a national park conservation area. Wildlife monitoring was conducted using camera traps operated continuously for 12 months at strategic locations, including wildlife trails, water sources, and habitat corridors. Independent detections were used to identify dominant potential prey and calculate the Relative Abundance Index (RAI), while predator–prey population dynamics were evaluated using a differential-equation model based on the Lotka–Volterra framework. The results indicated that wild boar, muntjac, and sambar were the dominant potential prey, with temporal variations in prey abundance followed by corresponding changes in dhole activity. Population modeling demonstrated cyclical predator–prey dynamics, suggesting that prey availability may influence dhole population responses. These findings highlight the potential role of dholes in regulating herbivore populations and maintaining trophic stability. Conservation management should therefore integrate predator protection, prey availability, habitat connectivity, and long-term population monitoring to maintain ecosystem balance in national park conservation areas.
