Abstract:
Generally, vegetation under oil palm stands are still considered as weeds or disturbing plants that must be controlled and the benefits are still below estimations. It is necessary to conduct research concerning identification of vegetation and structure composition under oil palm stands which can be used as cover crop by considering its ecological value. The research was conducted in 9, 13, and 18 years old of mature oil palm plantation in PTPN VII, South Lampung, Indonesia. The study used squares method, measuring 1 m x 1 m, by systematic sampling. Each location used a 1 m x 1 m observation plot with total observations plot is 25 plots per location. At each square, it was recorded and counted the type and number of individual weed, and then each type was separated, and dried to calculate the dominant value. The data obtained were analyzed by calculating K, KR, F, FR, D, DR, INP, and SDR. The results showed that there were differences of composition and vegetation type under 9,13,
and 18 years old of oil palm stands and the biodiversity was classified as high to very high.
