Sun bears in captivity require complex, naturalistic environments with climbing opportunities, foraging challenges, and social management to meet their behavioral needs.
Sun bears present specific welfare challenges because their arboreal lifestyle is difficult to accommodate in traditional zoo enclosures. Bears confined to flat, low-complexity enclosures without climbing structures cannot express a fundamental component of their behavioral repertoire. Sanctuaries like the Bornean Sun Bear Conservation Centre provide semi-wild forest enclosures where rescued bears can express natural behaviors — climbing, foraging, and independent ranging — demonstrating what genuinely welfare-positive captive environments can achieve. These facilities also serve critical conservation education functions, showing communities that bears have value alive.
