Response of young Douglas-fir to 16 years of intensive thinning

Creator:: Tappeiner, J. C. (John C.), Bell, John F., Brodie, J. Douglas (John Douglas), 1938-, and Oregon State University. Forest Research Laboratory
Abstract:: A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...

The Cochran airplane seeding experiment : preliminary report

Creator:: Woods, John B. (John Burton), 1890- and Hann, John H.
Abstract:: "One of the basic problems of forest management is that of restoring to productivity denuded areas which cannot be expected to restock through natural means. The most efficient method of regenerating such lands is that method which provides adequate restocking in the shortest time with the least expense. Successful direct...
