Abstract
Results of a survey of intensive forest-culture practices on forest-industry lands in the North. Timber-stand improvement and commercial thinning have been and apparently will continue to be the most popular practices undertaken. Estimated increases in recent annual harvests due to intensive culture averaged about 4 percent, and greater increases are expected during the next decade. Industrial managers expressed a high-priority need for more knowledge about genetic tree improvement, site preparation, fertilization, and species conversion.
