Greetings Phil:
Even though high-value hardwoods rule the roost here in Illinois, there is a modest market for coniferous species (log cabin logs, pulpwood, dimensional lumber, utility poles, fuelwood, mulch, etc.). Therefore, I strongly encourage you to contact a local professional consulting forester to determine the feasibility and logistics of conducting a commercial timber sale within this stand of white pine.
