Formosan Black Bear

Fewer than 1,000 Formosan Black Bears (Ursus thibetanus formosanus) survive in the wild — and that scarcity is precisely what earns this subspecies the top rank among Taiwan's wildlife encounters. Confined to mountain forests above 1,000 metres across the Central Mountain Range, the animal has been legally protected since 1989, yet illegal snaring remains the primary recorded cause of mortality. Taiwan's Forestry and Nature Conservation Agency logged just 742 confirmed camera-trap sightings across all monitored zones in 2023, making a live encounter one of the rarest wildlife experiences in East Asia — significantly rarer than spotting a Green Sea Turtle on Little Liuqiu, which has over 90% sighting success. Guided multi-day expeditions into Yushan or Taroko's backcountry offer the best odds, though no operator can guarantee a sighting; dawn vigils near stream corridors and fruiting fig trees yield the most results. The bear's distinctive white V-shaped chest marking — giving it the Chinese name 月熊, or moon bear — is unmistakable in the brief seconds a forest crossing usually allows.
