Yakushima Island

The west-coastal part of Yakushima Island is covered with precious laurel forest, registered in the world natural heritage of UNESCO. Yakushima macaques and deer are living in the forest with high density, and plant-animal interaction is one of important processes to keep the forest in good shape.

For conservation of Pinus armandii var. amamiana, we have researched suitable site for its regeneration and co-existing mechanism with broad-leaved trees.
