This study aimed to evaluate the effects of different revegetation methods on surface erosion of the devastated hillslopes of limestone quarry at Okgye, located in Baekdudaegan, Gangwon-do, South Korea. Four methods, namely the coir-net-method, geofiber-method, green-slope-soil-method, and latticed-frame-attaching-method, were applied to four survey plots (2 m × 2 m), and different parameters, e.g., coverage, vegetation (the number of species and population), soil hardness, soil humidity, and surface erosion were determined. The survey plots in each case were selected, considering the differences in their altitude and slope angles, for appropriate comparison of the effects. The results showed that surface erosion was lowest for the geofiber-method, and was followed by erosion in the plots in which the green-slope-soil-method, latticed-frame-attaching-method, and coir-net-method were applied. In addition, the coverage rates for the geofiber-method and the green-slope-soil-method were relatively higher compared to those for the latticed-frame-attaching-method and coir-net-method. The above results indicate that the geofiber-method and green-slope-soil-method are relatively more effective in promoting vegetation growth and in minimizing surface erosion by adhesion the base materials.
