Conservazione

This woodpecker is critically endangered. It has a single tiny, declining population which is threatened by habitat loss of mature forest due to logging, dam construction, agriculture, military and golf course developments. A major problem now is that one of their main habitats is being destroyed. The current population is estimated at less than 600. This species is suspected to be declining at a rate of 10-19% over ten years, as a result of ongoing clearance of old-growth forests.<p>This woodpecker is legally protected in Japan. It occurs in Yonaha-dake Prefecture Protection Area and small protected areas on Mount Ibu and Mount Nishime and conservation organisations have purchased sites where it occurs, but it is mainly found in the Okinawa Prefecture. In 1996, Yambaru was designated as a national park.<p>The habitat of the Okinawa woodpecker is threatened by the construction of six new American helipads located about 9.5 km Southwest of the Yanbaru forest of Takae. The lives of the birds themselves are also put at risk by the flights of V-22 Ospreys over the island.
