Longbeard is right. Sawtooth oaks are fast growing and will start producing in about 5 yrs. (some reports have them producing in 3 but IMO that is a rare occurance). You can get bare root trees in the late fall and early winter for a about a buck a piece. A friend bought a sack if 60 and gave me 40 of them. I planted 24 on my 80 and have the rest growing in pots at my house. Plan on putting them out next winter.
Heres a link to some info on acorns and oak trees that deer prefer.
