In most national forests in which regenerated stands will have considerably higher volumes than present stands, large increases in harvest during the first decade can be attained, under nondeclining yield, by allowing variable rotations for regenerated timber starting at age of first commercial thinning. Where regenerated volumes will not exceed those of existing stands, the increase will be negligible. Whatever minimum age is used, variable rotations will facilitate attainment of nondeclining yield over the entire planning horizon.
The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
