Creator:: Kelsey, Rick G. and Joseph, Gladwin
Abstract:: Diseased and healthy Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were identified at two black-stain root disease centers, caused by Leptographium wageneri var. pseudotsugae Harrington & Cobb, in the Oregon Coast Range near Coos Bay. Phloem and sapwood near the root collar were sampled monthly for 1 year, whereas roots were sampled...

Creator:: Watt, Abby J., Fischer, Dylan G., Antos, Joseph A., and Zobel, Donald B.
Abstract:: Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...

Abstract:: The use of clonal varieties in forestry offers great potential to improve growth traits (quantity) and wood properties (quality) of loblolly pine (Pinus taeda L.). Loblolly pine trees established via somatic embryogenesis (clones), full-sib zygotic crosses, and half-sib zygotic open-pollinated families were sampled to identify variation in growth and wood...

Creator:: Soto, Daniel P., Donoso, Pablo J., Salas, Christian, and Puettmann, Klaus J.
Abstract:: We evaluated effects of top-soil scarification by heavy machinery on growth of two valuable and shade-intolerant tree species - Nothofagus dombeyi (evergreen and considered very plastic to different soil fertility levels) and Nothofagus alpina (deciduous and considered sensitive to soil fertility) - seedlings underplanted in Nothofagus old-growth forests subjected to...

Abstract:: Abstract: Genetic variation in drought hardiness traits and their genetic correlations with growth potential and17re1c6overy traits were investigated in 39 full-sib families of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from southwestern British Columbia. Seedlings of these families were grown in raised nursery beds and subjected to three moisture...

Creator:: Homann, Peter S., Caldwell, Bruce A., Chappell, H. N., Sollins, Phillip, and Swanston, Chris W.
Abstract:: Chemical and microbial soil properties were assessed in paired unfertilized and urea fertilized (>89 g N·m–2) plots in 13 second-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands distributed throughout western Washington and Oregon. A decade following the termination of fertilization, fertilized plots averaged 28% higher total N in the O layer...

Abstract:: The effects of initial leaf litter chemistry on first-year decomposition rates were studied for 16 common Pacific Northwest conifers, hardwoods, and shrubs at the H.J. Andrews Experimental Forest in western Oregon. Leaf litters were analyzed for C, N, P, K, Ca, Mg, proximate organic fractions (nonpolar, polar, acid-hydrolyzable extractives, acid-hydrolyzable...
