In snowy Shirakami-Sanchi, a pure forest of Siebold's beech that well withstands the snow has developed. The site of woods with straight grayish-white beech tree trunks lined up against forest floors covered with dwarf bamboo is a distinctive scene that can only be observed with the beech fores ts in East Asia. Siebold's beech trees are also known for their high water retention capacity and their importance as habitats for wildlife.
