Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:

Nabel, Mark R.

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...

Early competitive interactions between red alder and salmonberry in the Oregon Coast Range

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...

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...
