Wuzhishan breed is very quickly being forced out of existence. They are a local breed raised only in the province of Hainan, China. This area is a geographically isolated tropical mountainous region. Very few people in this region raise this breed for production purposes because of the fast introduction of exotic species. Special attention is needed in order to preserve this rare species. There are fewer than 30 Wuzhishan pigs remaining, with only 3 boars, and all are in ex situ conservation.
