The relationship between natural regeneration and land/forest description was analyzed by the Quantification-I method using the data on natural regeneration, collected in cool-temperate and boreal forests in central Hokkaido. The number of naturally regenerated trees varied markedly with the type of floor vegetation, number of trees and mixing rate of conifer, but slightly with the azimuth and topography of forest stand. The number of naturally regenerated trees tended to be large in the area with floor vegetation of Saga nipponica and other grasses: It also tended to be large in the area with a large number of trees and a high mixing rate of conifer. These results suggest that two ways are effective for the natural regeneration where the forest floor is covered with bamboo grass; one is removing bamboo grass from the floor by using bulldozers, and the other is reducing culm density of bamboo grass by planting conifer on the floor
