Abstract
The habitats of Bletilla striata, which is a vulnerable species, were found on some artificial vertical cut slopes surrounding paddy fields at Mobara city and neighboring towns in China prefecture. Growing conditions and environmental factors of these habitats were studied. Leaf siza and number of flowers differ among populations. At some places, they depressed by shade of trees above the slopes and other competing plant species. In addition to keep these slopes without land development, annual cutting of trees and weeds at adequate season is necessary to conserve Bletilla striata community.
