This study analysed the impact of the Malayan Uniform management System (MUS) on liana abundance and their relationship\r\nwith trees in the Bukit Panchor Forest Reserve Malaysia. Two types of MUS-treated forest medium-term MUS\r\n(M-MUS) and long-term MUS (L-MUS) were identified based on the management time span (19 and 42 years respectively).\r\nTrees with diameter at breast height = 10 cm were identified and examined for liana presence (diameter = 2 cm) in\r\nten 40 m × 40 m plots within each forest. Tree seedling and sapling abundance were also determined in a randomly selected\r\n20 m × 20 m subplot within each plot. Liana abundance and infestation rates were significantly higher in the untreated\r\nforest than under the M-MUS although they did not differ from those under the L-MUS. Tree diameter related significantly\r\nwith liana load and basal area in all the forests except the M-MUS which contained relatively more uniform diameter trees.\r\nReduction in liana abundance and infestation in the treated forests favoured natural regeneration of the trees. Liana cutting\r\nwas effective in reducing liana abundance and infestation in the medium term but not in the long term. Therefore further\r\nliana cutting in the long term may be needed to control lianas.
