You are absolutely right Rex, forgive me.
I have paired sales data showing $500/acre contributory value for select hardwood harvests, but that's in my market. Side by side parcels, one harvested, one not, and the owner (on a phone interview) disclosed the harvest value. We affect larger parcels for projects, so wooded/vacant/farm/timbered/recreational are amenities that are given consideration for value when we acquire land. Unfortunately that data is several states away and is meaningless to the op's area.
Our farm was harvested (85 acres) back in the late 90's (prior to our ownership), so the data is too old to support any conclusion. This was also a select cut for hardwoods, no pine involved.
We should defer to Terrell's sage suggestion of a timber cruise and not speculate on a child's future education based on assessment photos and a CR's out of state minimal timber value experience.
