Book Description
The trend in forestry is toward shorter rotations and more complete utiliza tion of trees. The reasons are: (1) financial pressures to obtain rapid returns on the forestry investment made possible by an earlier harvest; (2) enforced harvest of young plantations to maintain a continuing supply of cellulose for mills where wood shortages are experienced; (3) thinning young plantations, both because they were planted too densely initially and because thinning is done where long rotation quality trees are the forestry goal; (4) more intensive utilization is being done using tops and small diameter trees; and (5) there is interest in using young (juvenile) wood for special products because of its unique characteristics and the development of new technologies. The largest present-day source of conifer juvenile wood is from thinnings of plantations where millions of hectares of pine were planted too densely. Because of the better growth rate resulting from improved silviculture and good genetic stock, plantations will need to be thinned heavily. As a result of this trend, young wood makes up an increasingly larger proportion of the total conifer wood supply each year. Large amounts of juvenile wood from hard woods are also currently available, especially in the tropics and subtropics, because of the fast growth rate of the species used, which results in shorter rotations and ess~ntially all juvenile wood.

Book Description
International Review of Forestry Research, Volume 2 is a collection of reviews and summaries of world literature concerning trees, forests, and forestry. This volume is divided into six chapters, and begins with a brief presentation of the historical developments of forest science and forestry research in East Asia. The succeeding chapters evaluate the influence of spacing on the growth and development of different coniferous tree species, as well as the influence of silvicultural practices on wood quality. These topics are followed by discussions on the various aspects of forest meteorology and the optimal conditions for vigorous root growth. The final chapter looks into the successions of organisms in discoloration and decay processes in living trees. This book will prove useful to forest scientists, research workers, teachers, advanced students, administrators, economists, and forest and land managers.
