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...

Brodie, J. Douglas (John Douglas), 1938-, Black, Hugh C., 1941-, Dimock, Edward J., Evans, James, 1930-, Kao, Chiang, Rochelle, James Arthur, 1942-, and Oregon State University. Forest Research Laboratory

Abstract:

Regression models of height growth and survival were fitted to aggregate data for trees, protected and not protected from animal damage, that had been surveyed on Douglas-fir and ponderosa pine plantations in Oregon and Washington. Animal damage significantly affected both height and survival. Dynamic programming analysis-using both soil expectation (Se)...
