Double or triple sorting of tree lots

Double or triple sorting of tree lots is dividing them into two or three segments by height, caliper or root mass. Most of the time it is on height or caliper. These two elements are quite closely correlated, so in most cases it can be done on height alone. The nurseryman and field forester should sample-measure a lot of trees to establish a height caliper relationship. Then they should agree on a height separation so the tree lot can be sorted on the most obvious element. This will allow a small percentage of the trees below the desired caliper to go to the upper height class, but this should be accepted by the field and, if necessary, the field can compensate by planting a few more trees per acre.
