In order to avoid negative impacts on replacement of the vetiver by vigorous local weeds, approximately 150,000 slips of vetiver were planted with suitable closely-spaced plantations (planting in rows 30 cm apart). Shade tolerant species of vetiver were applied in the shaded area of rubber plantations. Geotechnical remedial measures include green gabion wall, green reno-mattress, erosion control mat, hydroseeding, driven soil nail and surface drainage system
