A total 236 species have defined by field survey. Combined with legacy documents previously, we have increased the list of butterflies in Bach Ma National Park in total 361 species. Nymphalidae have the greatest of genus number and species number and lowest is Riodinidae. Savanna has the highest species richness (d=17,75) and lowest is Natural closed forest (d=7,54). The eveness index is highest in Natural closed forest (J’=0,886) and lowest in Agricultural cultivated land (J’=0,667). The diversity index is highest in Savanna (H’=4,075) and lowest in Agricultural cultivated land (H’=2,783). The species richnees index in under 1000m altitude is higher than over 1000m altitude. This is result when comparing the diversity index in this altitudes. The eveness index in over 1000m is higher than under 1000m. The similarity index is highest in between Savanna and Planted forest (SI=49,1%) and lowest in between Natural cloesd forest (SI=21,3%). The similarity index between altitudes is 32,5%.
