Tsuga sieboldii forest in Miyajima Island
Primaeval forests with least human disturbances are distributed in Misen and northern Komagabayashi, and have been assigned as a national monument Misen Primaeval Forest. Tsuga forests lie at the center of the primaeval forest.
Based on the vertical distribution of vegetation in Japan, Tsuga forest belongs to the intermediate zone. Although Tsuga forests in Miyajima is located in Mount Misen, Komagabayashi and Mount Iwafune, the total area explained only 4.5% (1.4 km²) of the island. Because Tsuga forests remain least on most islands in Seto Inland Sea, the Tsuga forests is valuable. Tsuga forests in Miyajima are often accompanied with Chamaecyparis obtusa (Siebold et Zucc.) Endl., Pieris japonica (Thunb.) D. Don ex G. Don, Rhododendron reticulatum D. Don ex G. Don, Rhododendron lagopus Nakai var. lagopus, Davallia mariesii T. Moore ex Baker, Hymenophyllum barbatum (Bosch) Baker, etc. The forest type is classified into Pieri-Tsugetum association (Yamanaka 1961). tentatively translated (a signboard on Mount Misen, 2014-03-17)
