Asian black bear
Five black bear populations, occurring in Kyushu, Shikoku, West-Chugoku, East-Chugoku and Kii areas, were listed as endangered by the Environmental Agency in the Japanese Red Data Book in 1991. Small isolated populations in the Tanzawa and Shimokita areas of mainland Honshū were listed as endangered in 1995. Beyond recognising these populations as endangered, there is still a lack of efficient conservation methods for Japanese black bears.
Formosan black bear
From 1998 to 2000, 15 Formosan black bears were captured and radio collared in Yushan National Park. Reported bear sightings are very infrequent and no one knows exactly how many bears still exist. The species has been legally protected since 1989 but illegal hunting continues and such poaching continues to threaten Formosan black bear populations. For example, eight of fifteen bears captured in the above survey had missing toes or paws, caused by illegal traps.
