4. =Selection of Desirable Species.= In the selection of desirable species there are a large number of considerations, and the first of these is the purpose of the owner in maintaining the woodlot. For instance, if the owner desires fence posts, and fencing material, his woodlot will, in Kentucky, be confined to those species which produce such material =quickly=, as for example black locust, catalpa, chestnut and walnut, also it will be well to have a percentage of red cedar (juniper) in the mixture, for since red cedar grows comparatively slowly, it may be reserved to be cut as the second crop and will serve to shade the ground and prevent erosion when the faster growing species have been cut and during the restocking of the area. If fuel as well as fence post material is desired, a mixture including hickory, oak and chestnut would be desirable. If ties, posts, poles or other products are an object, certain species are desirable and are easily grown. A list of trees suitable for various purposes is herewith given. No species are included in this list which will not produce marketable material repeatedly within the lifetime of a single individual. Only in unusual cases is the raising of trees for lumber recommended as a feasible or profitable venture for the individual farm owner. Fence posts and fencing material――Black locust, catalpa, chestnut, walnut, oak, red cedar (juniper). Fuel――Oak, hickory, maple, chestnut. Poles――Chestnut, catalpa, red cedar. Ties――Black locust, catalpa, chestnut, walnut, oak. Vehicle material and handle stock――Hickory.
