Actually it is a map from Ca F&W, the biologists I have talked with swear by it.
I doubt that map has ever been on the fish and game website. I also don’t think the biologists swear by it. I know many people that dna their bucks because they say their blacktails and there has yet to be a single one that is. Biologists I presume have some of that data so I doubt they swear by a map that looks 30 years old. Just what I think though.
