Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Creator:: Kelly, Linda Susan
Abstract:: General outcomes of this study show that early growth of planted red alder is often slowed in the presence of neighboring vegetation, and overwhelmingly by salmonberry, a common associate in disturbed Oregon Coast Range habitats. Additionally, young red alder plantations located in riparian areas may be highly susceptible to frost...

Creator:: Hyatt, Joan Marie
Abstract:: The growth of western hemlock during the first four years of seedling establishment was examined in a competitive environment in which seedlings were exposed to various types of animal damage and salmonberry and/or alder competition. The study utilized an existing Nelder/replacement series experiment which focused on the competitive effects among...

Creator:: Miller, James H.
Abstract:: Nutrient losses of the biologically responsive anions, nitrate and bicarbonate together with the major cations, were monitored on 14 small watersheds in Oregon's Coast Range and evaluated in relation to management-induced disturbance. Mixed forests of Douglas-fir and red alder had dominated these high-nitrogen sites prior to treatment. A paired-watershed experimental...
