In order to prevent soil erosion and promote reforestation on devastated bare slopes, the ecological new technology using MS (Mulching Sheet: nonwoven fabric sheet with two to four layer structures) and GB (Green Bag: made of MS containing plant seeds, fertilizers, vegetation base materials, and mycorrhizal fungi) has been applied to bare slopes not only in Japan but also in Korea, Taiwan, China, Indonesia, Vietnam etc. since 1990.From the results of them, the following conclusions were obtained: (1) This technology was significantly effective in preventing soil erosion and promoting the early revegetation on bare slopes; (2) It was suggested that the initial reforestation period could be accelerated for about 50 years by this technology in the Temperate Zone by many field data obtained.
