Abstract |
Miyajima (Itsukushima) Island, Hatsukaichi City, Hiroshima Prefecture, is a protected area that serves as the core and buffer zones of Itsukushima Shrine, a World Heritage Site. The Dondon-gawa River on Miyajima Island has its upper stream located on a mountain slope and flows through the town area. A dam is planned to be built on the river to prevent erosion. Since the construction of the dam will involve removing forest and will also affect the plants on the forest floor, we investigated vascular plants to evaluate the species composition and distribution in the planned dam construction area. We confirmed the presence of 124 species (1 lycopod, 12 ferns, 102 angiosperms, and 9 gymnosperms; including both native and naturalized species). Some specimens were unidentifiable by morphology because of dwarfing and unconfirmed flowering due to deer browsing and therefore required DNA barcoding for identification. We also found in the forest bed some rare species listed in the Red List of Hiroshima Prefecture. Consideration should be given to the dam's location for the conservation of these species, together with an assessment of the environmental impact of the dam's placement.
