I have about 9 acres of timber on my property and a lumber company wants to...
The recommendation would be to get someone involved that knows timber. Someone who can act as an agent for you when it comes to which trees to harvest, how to manage the harvest and the clean up.
The Ohio Division of Forestry does offer a service of walking you wood lot and giving some advice. They do not do all of the stuff I mentioned above. A consulting forester would be best for this.
Here are a couple of people that I would suggest you call before proceeding:
Dave Apsley with OSU Extension is this area of specialization, 740-710-3009.
or Ben Robinson with Ohio Div. of Forestry
