RE: Need forest harvesting info.
My experience with timber is this. It is a real dirty business. There is just so much wiggle room in it. This tree is not veneer (high price) when it is. The board feet they say is less than actual. Also there are two ways to calculate board feet (doyle scale and international scale) one results in more board feet. Obviously the buyer wants to use the lesser scale. I have actually had buyers say the log is not veneer and a veneer buyer then show up and say they will take that log.
A must is to know how many trees and board feet that are there before they are cut. If you can't do this yourself you must find someone you trust that will do it for you. This can also be difficult to do.
Black Walnut is a top quality tree maybe the best it is right up there with cherry etc. What ever the person does do not give away your black walnut tree the are worth quite a bit.
