Abstract

We examined the effects of anthropogenic disturbance on the water chemistry, hydrology and vegetation of an ombrotrophic mire located in Kuromatsunai (42° 38' N, 140° 21' E, 95m in altitude). Peat water around the top of the peat dome exhibited a pH of 4.3-4.7 and 4.4-5.2m/m of EC. However, at the edge of the road the pH was found to be in excess of 5.5 with 8 m/m of EC, and contained considerable amounts of Na and Ca. The polluted area and resulting deterioration of wetland vegetation was limited to an area within 15 meters from the road, so it will be important to maintain the existing conditions. Sasa (Sasa megalophylia) covered the vicinity of the drainage channels and had displaced the more vulnerable wetland vegetation. The pH and EC values in the Sasa community did not differ significantly from those of the ombrotrophic areas. This suggests that nutrient-rich water in the channel might not be flowing into the Sasa areas. Accordingly, the drainage effects of the channels, which might cause an expansion of the Sasa community, must be removed.
