Abstract

The continuing expansion of oil palm plantations has drawn a lot of attention regarding its impact on the environment, including the presence of wildlife in it. Through this research, the impact of oil palm plantation expansion on the bird community is evaluated. The research was conducted in February 2018 on a Plantation in South Sumatera (PHLE). Data collection was implemented in 5 different tracks of three different land-use, including shrub cover (as the baseline), oil palm stands, and high conservation value area (HCV), using the line transect method with a total of three repetitions in each track. The results show an increase in bird diversity from 19 species to 24 species and also an increase in the richness index from 3.69 to 5.41. The land cover change did not adversely influence the bird species composition, which was shown by the total of Sorensen similarity index on oil palm plantation area and shrub area of about 54%. This means that the composition was the same. The existence of the oil palm plantation area caused the loss of 5 bird species. However, 19 species were gained in the oil palm plantation area.
