We had a small cedar tree up on a hill that was rubbed every year. My father had a stand that over looked it and have taken several nice bucks from that stand over the years. He even said that he watched several bucks rubbing their antlers as well as numerous does scratching on it during several of his sits. Well, over time, for whatever reason, the cedar died. For 2 straight years, that stand was unproductive and the deer sightings dropped off dramatically at that stand. Come that Spring, my father planted a healthy sized cedar in the very spot the old one grew. The new cedar is rubbed every year and the deer sightings off that stand has jumped up significantly. Its a community rub and form of communication for the deer on our property. So one tree can make a difference in my opinion.
