Abstract
Revegetation of bare slopes on a dam lake frontage was tested with palm fiber roll, which has previously been a successful and efficient material on riverside plantings. Palm fiber roll was laid along the direction of the contour as a flat layer or an alternative wickerwork. Observations, during the first 2 years following establishment, are that:(1) Both types of bank protection and materials have remained intact.(2) Few plantings have drifted.(3) Ratio of plant survival has stabilized.(4) Height of plantings has increased. In this instance, since it is difficult to use heavy machines, palm fiber roll seems an efficient material for the preparation and stabilization of planting ground because of its lightness, flexibility and strength. These preliminary observations suggest that both of these slope protection methods are potentially efficient for the revegetation of bare slopes on dam lake frontages.
