How is it getting too large? I’d like to hear what you’re thinking.
Some mills around here have a max butt size, but too large is generally not a problem. Most loggers I deal with sort and merchandise our trees. Meaning someone will take the larger butt cuts. Also your dbh average (I’ll bet) of oversized trees is probably very, very small. I’m guessing.
We had a “bottom land” tract that wasn’t but 23 years old, but had a few trees on the edges and roads that were over 20” dbh, but when we cruised it, there were only a handful of trees actually out in the stand like that. Less than a load or 2 on 80 acres. I’d like to hear your situation.
My dad gets a green sheet every quarter, but forest 2 market or timber mart south usually has prices, but it’s all negotiable.
