Silviculture is the art and science of forest management. It encompasses the management of forests for economic benefit (such as sawlogs, veneer logs, honey), environmental benefit (such as flora, fauna, water) and social benefit (such as visual landscape, recreation, heritage). Often these benefits are not compatible. For example, the highest economic return may be gained by clearfelling a forest, but this can have detrimental effects on environmental and social values. Silviculture is a science because there is much known about the processes that occur naturally in
native forests, and the impact of these processes on the activities of people. However, forests are extremely complex natural systems. Determining the best management regime within the context of this complexity and the competing benefits that can be derived from the forest is the art of silviculture.
