Bryophyte colonies at Mt. Sanrei, Kayahage were investigated in the vegetation removal area by Shika deers. One hundred images of 1m×1m sub quadrate were combined by mosaic composite technique; so high resolution 10m×10m quadrate images were created. Distributions and coverages of each species were measured using these large images. After examination, eleven species of mosses were recorded on this area. The coverage of Agrostis clavata subsp. clavata (Poaceae) was 22.6%, and of mosses was 34.3% in the flat area quadrate and Atrichum spp. and Campylopus japonicus were formed large colonies. While the coverage of A. clavata was 21.4%, and of mosses was 23.5 % in the slope area quadrate, and Polytrichum commune, Atrichum spp. and Dicranum scoparium were formed large colonies. Development of Polytrichum commune colonies and others were also discussed.
