the green barked tree that te rubs are on....anyone know what kinda tree that is?

Where we hunt in Va. it seems that is the only tree they will rub...other area's they will rub the cedar's, smaller saplings....but this one particular parcel it seems that is the only tree the deer will hit or atleast prefer to hit....which I think is kinda odd. Have always wanted to know what is so appealing about it...but never knew what tree to look up... [&:]
