(this is the elephant, tiger, & bear preserve that I visited in October): This organization focuses on rescuing animals from bad zoos and circuses and roadside attractions, etc., but they probably know more than most people about how to respond to a situation like the bear-feeding situation (though they'll probably refer you to CDFG)

It's the rare wildlife center that takes bears, but you can call any center and ask the staff there for a referral to appropriate people (though they'll probably refer you to CDFG first)
