I have years of experience and a BS in Wildlife management, you will have to give me stronger arguments against an oak that will produce an enormous quantity of acorns after only 15 years of growth. Yes there are a few species that produce more favorable acorns but none that compare to quickness and quantity of the saw tooth. Today's society wants instant gratification and the saw tooth oak is the way to go. Whether they are native or introduced? What is one negative aspect of a saw tooth oak?
