Ecosystem Protection

In order to continue sustainable development of the Geopark and to ensure its existence for the next generation we must take action to preserve it.

Environmental protection efforts are carried out on the Oki Islands in accordance with the environmental protection standards set by the Daisen-Oki National Park, Shimane Prefecture, and related towns and villages.

The Oki Islands UNESCO Global Geopark also contributes to environmental protection and conservation through its efforts toward the protection and research of native wildlife and the extermination of invasive species. The geopark encourages children to participate in these efforts. Additionally, notices prohibiting actions such as overhunting and littering are written on the sign boards at geosites.

The Protection of Precious Wildlife

About ten-thousand years ago, Oki separated from the mainland to become a group of islands. Moreover, due to the warm waters of the Tsushima Current, Oki’s climate is relatively warm and humid. Because of these conditions, many endemic sub-species reside in Oki.

However, invasive species such as the black bass, common dandelion, and ragweed threaten these endemic species and the ecosystems in which they live.

Awareness of this issue has led to growing research on ecosystems and plant distribution as well as independent invasive species extermination efforts by local residents.

Next Generation Initiatives

Atop the northern slopes of Mt. Washigamine in Northeastern Dōgo, sits a 20.58-hectare forest made up of 811 Japanese cedar trees that are 300 to 400 yearsvold along with thuja and fir trees.

The ancient people of Fuse Village (modern day Okinoshima Town), in the hope that the village remain forever rich in green, avoided practices of lumbering and cultivated forests of huge trees. They preserved these forests for future generations to inherit and to advocate for the value of bountiful forests and nature. Because of the ancient Fuse people, these forests have been protected from lumbering and preserved for hundreds of years.

Will this one decision, made so long ago, be what protects this precious forest into the future?
