The purpose of this study is to propose maintenance methods for these bryophytes based on the relationship between ground cover mosses and environmental factors. A Japanese garden in Kyoto city was selected as the study site. Using the belt transect method, 48 quadrats (20 cm × 20 cm) were established to investigate the influence of environmental factors on 9 species of major ground cover mosses. The environmental factors measured were as follows :solar radiation, water evaporation, soil hardness, soil water content, and soil pH. Detrended correspondence analysis indicated that the distribution of ground cover bryophytes was determined mainly by solar radiation, followed by grass cover. These environmental factors were related to tree coverage and weeding intensity, respectively. These results suggest that maintenance such as pruning of overgrown trees and daily weeding are important for ground cover mosses., Article, 信州大学農学部紀要 47(1-2): 35-40(2011)}, pages = {35--40}, title = {日本庭園における地生蘇苔類の管理手法}, volume = {47}, year = {2011} }
