Many different assets. In addition to the value of levels of management can bring all timber and other non-timber forest products which a woodlot can provide, it can also be a source of non-economic benefits such as abundant and clean water. A woodlot can make the local climate cooler and more pleasant in the summertime, warmer and less harsh in the wintertime, and protect the area from high winds. It can hold and enrich the soil by absorbing and releasing water slowly. Woodlots provide living space for a variety of plants, animals, birds and insects, some of which can control agricultural pests. Eastern Kentucky is the more heavily forested part of the state. The original forest was filled with trees of great value: American chestnut, oaks, black walnut, and yellow-poplar. After European Figure 1. Commercial Forest Land settlement, the forests were periodically cut to remove only the most valuable species or individual trees, a harvesting practice known as high-grading. This pattern of cutting caused the remaining forest to decline in quality, just as the quality of a herd would decline if the best animals were sold and poorer animals were left to produce offspring. Sometimes the forests were simply cleared and burned to provide pasture and fields. Degrading the commercial value of the forest also decreased the ability of the forest system to retain water and provide living space for many different plants and animals.

Health is related to age, disease and/or insect attack, weather, fire, and rot.

Determining the health of the forest is there, and the soil and water resources helps landowners to make fairly straightforward. A healthy forest has the following: wiser management decisions. Some questions to consider while • most trees have few, if any, obvious defects (scars,rot, walking the land include: branch stubs, etc.); • are there valuable trees now growing on the land? • tree crowns are fully leafed out with a minimum of dead • are the tree species now on the land suited to the soils? branches; • how fast are the trees growing? • few (less than 10%) of the trees in the stand are dead. • where are the property boundaries and are they clearly • The vital statistics of the trees (number, size, species, marked? quality).

Then find the basal areas of each tree by the formula A=πr2, • The total area of land that is forested. Area can be where A is the basal area and r is radius. Basal area is usually calculated determined from the land deed and/or from aerial photos available on a per acre basis. Once you have calculated the basal area per acre and have decided what percentage you wish to remove, then you can calculate from the local county office of the U.S. Department of Agriculture’s the number of trees of a given diameter which should be removed to Farm Services Administration (FSA). achieve the desired residual basal area (see Figure 3, Appendix E).
