Spatial and Seasonal Variation of Dugong Feeding Grounds and Habitat Use in Intertidal Seagrass Meadows: A Case Study at Libong Island, Thailand
Mar. Mamm. Sci. https://doi.org/10.1111/mms.70067 Aug. 21, 2025
–ABSTRACT -- Dugong feeding trails serve as crucial indicators for monitoring the presence and foraging areas of dugongs within seagrass ecosystems. This study aimed to evaluate the community structure of seagrass meadows, nutrient concentrations, and their relationship to dugong feeding trails in the intertidal seagrass regions around Libong Island, Thailand, during the dry and wet seasons of 2022. Seagrass cover was found to be variable but generally sparse, averaging 22.92% of the sea floor. Most seagrass species exhibited similar carbon and nitrogen concentrations; however, the highest frequency of dugong feeding trails was recorded in meadows dominated by Halophila ovalis, the most prevalent species at our research sites. This finding suggests that seagrass availability plays a more significant role in influencing foraging patterns than nutrient composition. Additionally, larger dugongs were observed to be more active during the dry season, while calves were more frequently seen in the wet season as certain seagrass areas became more accessible. The absence of dugong trails in some locations during the wet season indicates potential shifts in habitat use due to seasonal changes in seagrass availability. This study has important implications for dugong conservation and highlights the benefits of monitoring feeding trails to better understand habitat use, population demographics, and seasonal activity variations.
