This large fern thrives in damp habitats such as mountain valleys. It can form dense stands, sometimes so thick that the ground beneath becomes invisible. Being one of the most characteristic ferns of Tokunoshima, it can reach over 2 m in height, with leaves growing up to 1 m long.

Habitat of This Animal:
B:Forest along the mountain ridge - B2:Deep forest
As time passes from the felling of trees, trees in the forest will grow taller and thicker. Tall trees like Castanopsis, a representative tree of forests in Tokunoshima Island, form the forest canopy. Different layers of plants are formed beneath it, including medium-to-small trees and bottom weeds, and the forest floor becomes gradually darker. Through such a process, the forest will become deeper, supporting the fauna of Tokunoshima Island.
