Excerpts from the report: The essence of forestry--the art and science of growing forests--is called silviculture. And that is what this booklet is all about. Of course, there is more to forestry than silviculture, but understanding the basic silvicultural options available for treating a forest is a first big step in exploring the entire range of forestry. In its broadest sense, forestry includes economic, social, and philosophical as well as biological considerations; silviculture deals primarily with the biological aspects of growing trees. Despite its recent emergences as a national "issue", forestry--and more specifically, silviculture--is not a new invention. It has been known and practiced in Europe for hundreds of years and in this country for nearly a century.
