Creator:: Burney, Owen T.
Abstract:: The overall purpose of this study was to examine the root and shoot development of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings at two distinct time periods in seedling establishment (after I and 3 growing seasons) in response to fertilizer, stock size, vegetation control, and soil moisture treatments. Two separate experiments...

Creator:: Arellano Ogaz, Eduardo
Abstract:: Soil physical, chemical, and biological components as well as climate and physiographic characteristics can interact to have a great effect on forest regeneration and seedling growth response to different establishment activities. The objective of this project was to increase the understanding of the interactions between soil type, controlled-release fertilizers, and...

Creator:: Crane, Gabriel A.
Abstract:: A series of studies and replicated field sites were implemented in the Oregon Coast Range within Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) sapling plantations infected with varying levels of Swiss needle cast (SNC) caused by the fungus, Phaeocryptopus gaeumannii (Rhode) Petrak (PG). This research was conducted to understand the effects of...

Creator:: Goracke, Heidi S. Roe
Abstract:: Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and duration of vegetation control on wood quality near the pith...
