You can sell your trees by cutting them down and selling the cut product or by allowing the buyer to cut and haul the trees. A private harvesting company can also take the trees down for you.
In order to sell trees, you need to determine first if your trees have sufficient value and volume. The U.S. Department of Agriculture Forest Service provides an online guide on timber and log price information for each state, which includes the name and contact information of a wood marketing specialist. While the state-wide price information gives a general idea of the price trends, the value of the timber is mostly dependent on the local market conditions and the local timber harvesting laws as well as the conditions of the site where the trees are grown.
Contacting and working with a professional forestry consultant is a convenient method to sell your trees. A professional forester can help determine the value of your trees and provide assistance in the selling process. You may also contact the local Department of Natural Resources agency to ask for the assistance of a forest extension agent. The DNR and some County Agricultural Extension offices offer free services, including the assistance of a professional forester.
