SAKURAJIMA JF - GEOMATE Journal JA - INTERNATIONAL JOURNAL OF GEOMATE VL - 11 IS - 23 SE - Articles DO - UR - https://geomatejournal.com/geomate/article/view/2205 SP - 2136-2142 AB - <p>The utilization of exotic grasses as cover plants for erosion control has received considerable <br>attention in recent years, particularly because these exotic grasses have the potential to become invasive. This <br>study examined succession of exotic grass communities that have been established on the cut slopes of the <br>volcano, Mt. Sakurajima. The results showed that although the exotic grasses, such as Cynodon dactylon, <br>Festuca rubra and Dactylis glomerata, that have been used for erosion control on the cut slopes were dominant <br>for the first two years, marked decreases were observed as the native herbaceous plant, Miscanthus sinensis, <br>became dominant after three years. By the sixth year, all of the exotic grasses vanished completely. This high <br>rate of succession would result in the suppression of exotic grass dispersal on Mt. Sakurajima. It was also <br>suggested that the chemical properties of volcanic soils, and the bio-engineering technique employed on Mt. <br>Sakurajima may have facilitated this high rate of succession.</p> ER -
