Here, we have deer problems. Eat lots of the local foliage. They love
roses. Local nursery never has to prune their roses. There are about
10,000 deer killed by hunters, about a million killed by cars in Calif.
When you say "deer problems," you mean the problems created by mankind
encroaching on their environment and leaving them little option but to
forage and, of course, mankind has also killed off many of the natural predators of deer.
It's not a deer problem except in the abstract. It's a people problem.
