Are you talking the American hazelnut bush or the commercially grown trees. If it is the brush, I got 100 acres that you can dig up thousands if you want. The deer browse them and they produce great cover , but the good is really not consumed by deer. The squirrels and chipmunks live them and try bears go crazy over them. They eat the husks and all. Mine don't get much over 10 foot tall. My uncle says we have 2 kinds native to our area. I personally can't tell the difference in them.
