Alpine flora such as dwarf Japanese yew trees dominate the shrub forest zone at 1,600 meters in Daisen-Oki National Park and dogtooth violets bloom on Mount Kenashi and Mount Giboshiyama.
On the low-lying coastline of the Oki Islands, vegetation from around Japan coexist, such as Ramanas roses, which are normally found in the north, and Nago orchids, normally found in the south. The islands are also home to one of the largest seagrass beds in the Sea of Japan and the indigenous Oki salamander.
The rocky shores of Shimane Peninsula are an ideal breeding ground for seabirds. Fumishima Island off the coast is one of Japan's most vital rookeries for the black-tailed gull.
