Planted forests have superseded naturally regenerating forests as the principal source of industrial forest products. This change has many policy implications, not least that it diminishes the significance of naturally regenerating forests for wood production, thus releasing them to be managed for other purposes including protection, conservation and recreation. This book presents the data and analysis for planted forests and examines the consequences by evaluating the implications of this rapidly emerging world resource both as a source of forest products and as a social and ecological service.
