Tree species selection and cultivation techniques were determined in the 3 sites based on the water level, survival rates of different plants, and the growth performance in dry and wet seasons. We also analyzed the causes of the tree death and decay to find alternative plant species. The results showed that the plant growth was different under dif- ferent water levels. With the rise of altitude, the
