To evaluate revegetation, we established 7 plots. Each plot was set up with a vegetation-mat without seeds. For up to 7 years thereafter, we continuously surveyed the vegetation of each plot. They showed different succession by site condition, at 57 months after establishment, the percentage vegetation cover in all plots were over 50%; furthermore, the dominance of trees (DT) had increased. To evaluate the revegetation, we used ecological indices. Based on the increase in the number of emergent species, restoration was deemed to have occurred in 5 plots. However, the H' diversity index, quotient of similarity and degree of succession of all plots had not increased continuously, indicating that all the plots were still in the early stages of restoration.
