In the present paper, the authors listed (1) Lichens, Musci, Pteridophyta and Spermatophyta collected, and (2) plant communities registered in Ukijima Mire centered at 43°56 NL and 142°58 EL, approximately 870 m in alt., C. Hokkaido. Furthermore the authors discussed on the standards of conservation values of species protected for nature conservation. Using the simplest standard for this, the following items were considered to be "Important species": A. Noticeable species in Taxonomy and Phytogeography, Cornus suecica Linn., Lycopodium inunddtutn Linn., Vaccinium microcarpum Linn., Eriocaulon sdchalinense Miyabe et Nakai; B. Valuable species for conservation, Sphagnum species; and C. Endangered or threatened species, Sphagnum species and Bonsai forms of Picea glehnii. Aside from the standards mentioned above, the authors designed "Degree of muddiness" or "Nukarumi-Do" in Japanese to estimate tolerance of plants to treading. From the results, the authors considered that it is imperative to protect the Caricetum limosae, the Scheuchzerio-Rhynchosporetum albae boreale and the Sphagnetea from the treading.
