In the mid-1960s, the Ayamedaira mire was trampled by hikers, creating about 1.2 hectares of bare land. It was the largest bare area in the Oze region. The restoration of the bare land was begun in 1966 by the Gunma prefectural board of education and has been led by the Oze Ringyo Co. Ltd. since 1969. Initially, peat blocks were transplanted and Carex michauxiana Boeck. subsp. asiatica Hultén was sown, but recovery did not progress due to the runoff of the peat. After that, wooden crates were installed to prevent the peat from flowing away and straw mats were used to cover the area after the sowing of C. michauxiana subsp. asiatica, resulting in a greening of about 90% of the area by 2008. However, 10% remained bare. Since 2009, the restoration projects for this bare land, have been conducted by sowing seeds of multiple species and scattering Sphagnum, thus a greening method is being established. This report summarizes these efforts to establish restoration in the Oze region.
