An uneven canopied and very conifer diverse forest on a serpentine substrate with up to 7 species of conifer groing together:
Pinus parviflora ゴヨウマツ
Pinus densiflora アカマツ
Cryptomeria japonica スギ
Thujopsis dolabrata アスナロ
Chameocyparis obtusa ヒノキ
Abies firma モミ
Sciadopitys verticillata コウヤマキ
Also, in the area were Torrya nucifera and Cephalotaxus harringtonia and Tsuga sieboldii.
This diversity is probably possible because of the low nutrient substrate slowing down the growth of all species so that no one can dominate the canopy.
