You could always tell when the mule deer pop got out of hand ...you would find evidence of mass winter starvation the next spring. Now they go just go down to the nearest suburb and dine on the landscaping.
Hunting would be a solution but the FS and Parks Services try their best to discourage those “nasty” guns.
mule deer nationwide are declining in numbers in alarming rates.....its good to hear they are doing well in Yosemite....they are an awesome animal....
