Trees increase in value as they increase in size. As trees grow larger, they contain more wood and - potentially - more high--quality wood. One strategy for producing value in farm and family woodlots is to make high-quality trees grow to a marketable size in the shortest time possible. To accelerate the growth of trees and their timber value, woodland owners use a thinning method called crop tree management (CTM).
CTM is an effective way to accelerate tree growth and produce higher wood quality and higher market value in anticipation of a future timber sale. CTM consists of three parts: 1. Selecting high-quality "crop trees". 2. Providing these crop trees with ample space to grow by removing the competition from neighboring trees. 3. Considering the next generation.
