Where this system is used, the seed trees should be marked with a band of paint completely around the trunk, so the loggers can see the marked trees from all directions. Shelterwood Cutting Shelterwood cutting differs from the seed-tree system in the number of trees left after cutting. The seed-tree system leaves comparatively few trees while the shelterwood system leaves many more, not only to produce seeds, but also to protect the site while the young trees are becoming established. The residual stand is later removed in one or more cutting operations. In this system, trees to be cut should be marked prior to each operation. This system has these advantages: It can be used with heavy seeded trees such as the oaks, the financial returns are spread over a period of years, and the forest maintains its esthetic values. It cannot, however, be used with species that demand a great deal of direct sunlight in the seedling stage. Diameter Limit Cutting In this system the cut is regulated by a minimum diameter limit, usually measured at stump height. This method is easy to supervise and apply, but its serious fault is that the diameter of a tree alone is not a good indication of whether it should be cut. Weak, de- formed, diseased, slow-growing trees below the designated diameter may be left, while many healthy trees may be cut just when they.
