In the early 2000’s the forestry service reintroduced brown bears into the San Bernardino Nat’l Forest. That is where I was hunting. I confirmed this with the Nat’l Forest office in Big Bear, CA.
I’m not sure where the confusion lies here but according to Fish And Wildlife, the only bears in the San Bernardino National Forest are Black Bears.

I did a Google search for Brown Bears reintroduced there and got exactly zero hits. If that had been the case I would have thought there would have been some record of it. In any event, this is off topic so apologies to the OP.
