? Nonstocked or cutover sites with competing vegetation and requiring site preparation prior to regeneration. 
> Nonstocked or cutover sites without significant competing vegetation not requiring site preparation for regeneration. 
* Sites stocked with low-quality trees or off-site species requiring conversion to preferred species to improve productivity. 
° Sites densely stocked with seedlings and/or saplings requiring precommercial thinning or similar treatments to reduce stocking and favor potential crop trees. 
° Sites densely stocked with immature but merchantable trees. 
’ Sites adequately stocked with trees, but with inhibiting vegetation. 
* Sites with mature or overmature sawtimber size trees. 
° Sites with merchantable trees excessively damaged by fire, insects, disease, wind, ice, or other destructive agents.
