A study on the vegetation succession of pioneer trees in landslide control areas

Located in subtropics, the steep terrain, concentrated rainy season, natural disaster, and artificial development have damaged the surface vegetation and resulted in soil loss and landslide in Taiwan. The control of landslide should stabilize the side slope as the priority. Furthermore, a proper engineering is applied to grow plants for the rapid forestation on landslide. Taking the location which has been done hydroseeding in the Shihmen Reservoir watershed as the example, the vegetation succession within the 8 years after the hydroseeding is investigated in this study. The growth and decline of pioneer trees like Rhus javanica is particularly discussed the vegetation recovery role and function on landslide. The research result could provide reference for the planning and design of vegetation recovery.
