Site details
Site description: It is located about 290 km south of Tokyo metropolitan area. The island has two volcanos, Mt Miharayama (701 m) on the southeast and Mt Hachijofuji (854 m) on the northwest. Besides, there is an uninhabited islet called Hachijokojima about 7.5 km northwest of Hachijojima. There are evergreen broadleaf forests on the side of Mt Miharayama, which has a long history as a volcano, while there is a wetland on the volcanic hill at the center of Mt Hachijofuji. Hachijokojima island still has evergreen broadleaf forests where Izu Islands Thrushes, Ijima's Leaf Warblers and Japanese Wood Pigeons live, but its vegetation has been being destroyed by feral goats in recent years.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
