Survival and growth of Douglas-fir seed sources in the Hospital Tract rangewide source archive plantation

Creator:: Gamble, William E., Adams, W. T., Tappeiner, J. C. (John C.), and Oregon State University. Forest Research Laboratory
Abstract:: "In 1954, Dr. Helge Irgens-Moller initiated a rangewide collection of seed and seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Nearly 700 trees or stands were sampled in 10 western states, Canada, and Mexico. From 1957 to 1971, 639 of these collections were planted in the Hospital Tract Rangewide Source Archive...

Effect of seedbeds on germination and survival of Douglas-fir

Creator:: Hermann, Richard K., Chilcote, William W., and Oregon State University. Forest Research Laboratory
Abstract:: Germination and survival of Douglas-fir on seedbeds of unburned, lightly burned, and severely burned soil, charcoal, litter, and sawdust, exposed to 100, 75, and 25 percent of full light, were studied on a south-facing clearcutting in the Coast range of Oregon. Irrespective of exposure to light, germination was best on...

Thinning ponderosa pine (Pinus ponderosa) stands reduces mortality while maintaining stand productivity

Creator:: Zhang, Jianwei, Ritchie, Martin W., Maguire, Douglas A., and Oliver, William W.
Abstract:: We analyzed 45 years of data collected from three ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) levels-of-growing-stock installations in Oregon (OR) and northern California (CA), USA, to determine the effect of stand density regimes on stand productivity and mortality. We found that periodic annual increment (PAI)...

Early growth of Douglas-fir in a reciprocal planting

Creator:: Ching, Kim K. and Oregon State University. Forest Research Laboratory
Abstract:: Survival and growth during three years at 8 out-planting areas are reported for Douglas-fir from 14 sources of seed. Early survival was highest near Nimpkish on Vancouver Island. At most plantations, trees from the local seed source grew as well as did those from the best three sources. Trees from...

Influence of forest age on forms of carbon in Douglas-fir soils in the Oregon Coast Range

Creator:: Entry, James A. and Emmingham, William H.
Abstract:: The amount and type of carbon (C) in a forest soil reflects the past balance between C accumulation and loss. In an old-growth forest soil, C is thought to be in dynamic equilibrium between accumulations and losses. Disturbance upsets this equilibrium by altering the microclimate, the amount and type of...

Effects of stand density on the growth of young Douglas-fir trees

Creator:: Woodruff, David R., Bond, Barbara J., Ritchie, Gary A., and Scott, William
Abstract:: The objectives of this study were (i) to provide further evidence of a positive correlation of stand density with early growth of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii); (ii) to determine when after planting the positive growth response occurs and how long it lasts; and (iii) to use...
