Abstract

Peat land conversion into oil palm plantations have an impact on changes in physical, chemical and biological soil peat. Ant community is one of the soil biotic components affected on changes in physical and chemical properties of soils. This study aims to analyze the community of ants on peat lands with palm stands from a young age to old age (oil palm stands of 2, 10, 15, 19 and 23 years). In this study, the stand ages of oil palms also represent the reclamation ages of peatland. The study showed peat lands with stands of oil palms from a young age to old age have different physical and chemical properties of soil. Ant communities in the five study sites varied in terms of species richness, density, diversity and similarity index. Species diversity (the number of ant species) on peat land with oil palm stands of a young age (2 years) and old age (19 and 23 years) was higher than in the location of palm stands with age of 10 and 15 years that were periodically flooded. Ant density on land with palm stands of a young age (2 years) was higher and significantly different compared with other stand locations (10, 15, 19 and 23 years). Ant abundance was positively correlated with the thickness of the peat and the levels of N, P, K, Ca and Mg of peat soil. Ant species of Solenopsis sp was the dominant invasive species population in almost all of oil palm stand lands. Diversity index of ant community tended to be higher in land with old palm stands and was an indication that the equilibrium level of the ant community structure in the this location is higher than in the palm land with young age. The similarity level of ant species on lands with palm stands of 2, 19 and 23 years old was higher (similarity index from 81.5 to 87%) than in the location of the other palm stands. The results of this study indicate that factors of oil palm stand age, significantly affect population density of ants. The highest density of ants was in younger stands of oil palms and was significantly different from other locations. Species richness (number of species) of ants between in the younger oil palm stands and in the older ages was relatively the same, except for the locations of oil palms which were the stagnant water periodically (locations of oil palm stands with ages of 10 and 15 years) having low species richness.
