How Can I Stop My Neighbor From Trespassing Onto My Property?

I have 3 1/2 acres of land. I have had it for 10 years. The owner on the west side cuts wood for a business. He continually keeps moving more and more onto my land, at one time even removing small saplings. I did not want to have issues with my neighbor but it has gotten to the point where I need to. He has even put a posted sign, right next to the cement post that marks the line only, which it is on my side of the line. What rights do I have in this case?

Your neighbor is trespassing on your land and stealing your property (trees). That can be prosecuted both civilly and criminally. I suggest you talk to an attorney experienced in real estate matters about your options (and the potential reaction to them).
