A survey of Indochinese silvered langurs (Trachypithecus germaini) in Phu Quoc National Park, Vietnam, conducted during the wet season, using eleven line transects over fourteen field days, obtained an estimate of 1,249.37 to 1,498.89 total animals in the strictly protected area. Other estimates of population were found for comparison. This population has the potential to be a stronghold for the species in Vietnam and globally. The degree of fragmentation within the population and the population size trends are unknown. More information is needed for the conservation of the population on Phu Quoc Island and the species as a whole.
