Brown bears rescued from bile farming, circuses, and tourist facilities require specialized rehabilitation that may span decades in sanctuary settings.
Rescued bears from exploitative industries show profound behavioral impairment from years of confinement — stereotypic pacing, self-injurious behaviors, and inability to respond to natural stimuli. Long-term rehabilitation in large naturalistic sanctuaries can partially restore welfare-positive behaviors but complete recovery from severe early deprivation is rare. Preventing bears from entering exploitative industries through legislation is far preferable to rescue rehabilitation.
