Impact of oil palm plantation on the butterfly diversity: a Case study in KGP & CNG, Ketapang, West Kalimantan

Abstract

Abstract Oil palm plantation in Indonesia is rapidly growing, encouraging the expansion of oil palm plantation area. The expansion estimated may decrease the biodiversity including the butterfly diversity. The research aimed to see the impact of oil palm plantation on the butterfly diversity that occurs in KGP and CNG oil palm plantation. The research was conducted in July 2018 by strip transect method. Impact of the establishment oil palm plantation on butterfly diversity was determined by comparing the current butterflies found on oil palm plantations area with the butterflies found on the baseline (shrub area). The result showed an increase in butterfly diversity and species richness index in KGP and CNG oil palm plantation. Total number of species and richness index in both oil palm plantations area were higher than the baseline area. The establishment of oil palm plantation in KGP oil palm plantation result gaining 22 species and losing 2 species, while in CNG oil palm plantation result is gaining 31 species and losing 5 species.
