Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

Factors affecting inter-tree root contact and the transmission of Phellinus weirii in young-growth Douglas-fir

Creator:: Reynolds, Keith M.
Abstract:: Groups of second-growth Douglas-fir (Mirb.) Franco were excavated in plots of two to six trees on two sites in the vicinity of Cowichan Lake, Vancouver Is., British Columbia. Eleven excavation plots provided 36 trees which could be studied in pairs (a total of 50 pairs) in order to ascertain the...

The effects of winter plant moisture stress on survival and growth of 2+0 Douglas-fir seedlings

Creator:: Daniels, Thomas Gary
Abstract:: The effects of winter plant moisture stress (P145) on bare-root 2+0 Douglas-fir (Pseudotsuga menziesii (Mirb.) Frañco) seedlings during nursery lifting and processing were studied. Seedlings were undercut at Ca. 4, 12, and 20 atm PMS during mid-February. Half of the seedlings undercut at 12 and 20 atm were not moistened...

Fungi associated with Douglas-fir seed during cone development, seed processing, and storage

Creator:: Gordon, Lewin Roland
Abstract:: The Pacific Coast form of Douglas-fir in natural forest succession is an intermediate species thriving in the Coast Range and Cascade Mountains of the Pacific Northwest. This species constitutes 26 percent of the standing timber in the United States, and 24 percent of the nation's annual timber harvest. Characteristics of...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Root initiation and differentiation in Pseudotsuga menziesii (Mirbel) Franco

Creator:: Bogar, Gerald Dale
Abstract:: Tissue differentiation of the primary root and its associated laterals is reported. Secretory elements are the first of the primary tissues to mature. They appear to be located between the precursory phloem and pericycle in the primary root, but are more closely associated with the pericycle in long lateral roots....

Early stages in plant succession on Douglas fir clearcuts on the Mary's Peak watershed near Corvallis, Oregon

Creator:: Brown, Eugene Allen
Abstract:: This study has been concerned with the patterns of vegetative changes which occur during the first five years following logging and burning on Douglas-fir clear cuts. Knowledge of the successional sequence in the coastal forests of western Oregon is of primary importance to those concerned with the management of this...
