Investing land and timber 10 pts best?

I am looking to invest in undeveloped large tracks of land for recreation and timber use. I can't seem to find a book or resource that explains the best way to pay, how to value the land and timber, tax information, timber management. Basically, all I know is the "going price" of land in my area. I would like to educate myself in land and timber without going to school. I almost have two B.S. degrees in business and medical fields...dDon't want to start another. All the book I have, teach development property and housing. I really can't ask a local forester. They know the ins and outs of buying land and timber and buy it out from under you. Any help or advice will be welcome. Thanks
