The welfare needs of brown bears in captivity and the sanctuary model that best meets those needs.
Brown bear welfare in captivity spans a wide range from truly excellent sanctuary conditions to the horrific circumstances of bile farms and entertainment bears. The sanctuary model — large naturalistic enclosures providing forest, water, and foraging complexity for rescued individual bears — represents the best achievable captive welfare for a species whose territorial needs cannot be fully met in any enclosure. The welfare priority for bears is their internal world: providing cognitive stimulation, physical activity, appropriate hibernation conditions, and freedom from fear and chronic stress rather than simply space per se.
