Bat population appears is maintained as the last habitat of these species in the La Ca Pagoda (old) area of the Khmer ethnic people in Tra Vinh. Methods are interview, count individuals in the habitat, species, population, determine the type of plants, the height of the living bats; results of the current status of species, quantity, distribution, residence and reproduction of species; impacts on 2 species of horse bats related to the conservation of horse bats; compared to previous by the Ehb function, with the parameters Hchb (Horseback bat community) the existence of the community compared to the previous time, at least 1 breeding season; Hhhb (Horse bat habitat) on living conditions; Hfhb (Horse bat food) on food sources for the community to live; Hphb (Horse bat protection) on conditions to protect the community; evaluated by score (0–1); the results the species Pteropus vampyrus decreased by 79.51%, the species Pteropus lylei increased by 6.8 times. The total number is 1239 individuals, including 1072 THB and 168 LHB. Both of these species have been recorded in previous surveys. The number of individuals counted was larger than the previous survey (1239 individuals compared to 957 individuals); the number of LHB in this survey was much smaller than the previous count (168 individuals compared to 820 individuals); the number of THB was 1072 individuals compared to 137 individuals). Using a function-based assessment method with ecologically relevant parameters can objectively assess the distribution and status of threatened populations to effectively protect their survival.
