| Outline of Final Research Achievements |
We classified the fen and bog communities distributed in 21 mires throughout Hokkaido.The 11 communities were extracted, and grouped into three, bog type, transition type and fen type, which indicate that the fen-bog gradient is the major community gradient among the variations in mire communities of lowland Hokkaido. The ratio of area occupied by bog was highest at Sarobetu (14.1%)located in Japan sea side, and decreasing to the following order; shibetsu(10.6%), Kushiro(2.2%), Kiritap(1.3%), Yufutsu(0.1%). Accordingly, bogs became larger from west to east along the Pacific Ocean side.We could find that some bog and trasision types were restricted in eastern Hokkaido only, and bogs were almost absent in middle and east parts of Pacific Ocean side. Calamagristis langsforffii-Carex lyngbyei communities belonged to fen type, but Carex lasiocarpa var. occultans -Carex limosa community belonged to transisional type.
