Whichevermost accurately describesyour place,it islikely somebody has invested someextensive time and effortto inventory the trees anddelineate the forest stands on the property. Like everything else there is a ton of info on the web. If the land has a tree harvest of acouple thousand $ completed every 5 or 15 years, don't worry about the tax implications. Pay the taxes and move on. However, if the amount of money changing hands with a timber harvest is tens of thousands of $, it would be best to seek out a CPA with experience handling farms and silviculture practices. The taxes and the application of the laws can be very, very complicated to make sure you don't pay any more than absolutely you have to.
