The effect of local stand structure on growth and growth efficiency in heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

Creator:: Mainwaring, Douglas B. and Maguire, Douglas A. (Douglas Alan)
Abstract:: Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex.

Forest soil characteristics in a chronosequence of harvested Douglas-fir forests

Creator:: Griffiths, Robert P. and Swanson, Alan K.
Abstract:: This study was designed to measure the microbiological and chemical characteristics of forest soils in a chronosequence of harvested Douglas-fir (Pseusotsuga menziesii (Mirb.) Franco) stands in different climatic settings. Mineral soil samples were collected along transects running from old-growth (OG) forests into harvested stands of ages 5, 15, and 40...

Ten-year growth and mortality in young Douglas-fir stands experiencing a range in Swiss needle cast severity

Creator:: Maguire, Douglas A., Mainwaring, Douglas B., and Kanaskie, Alan
Abstract:: Swiss needle cast, a foliar disease caused by the Ascomycete Phaeocryptopus gaeumannii (T. Rohde) Petr., continues to afflict Douglas-fir (Pseudotsuga menziesii (Mirb.)

Growth of Douglas-fir reproduction in the shade of a managed forest

Creator:: Del Rio, Ernest, Berg, Alan B., and Oregon State University. Forest Research Laboratory
Abstract:: Growth was assessed for Douglasfir reproduction which had established naturally beneath three intensities of overstory thinning in a 65-year-old stand of Douglas-fir on the east side of the Oregon Coast Range. The age of advanced reproduction ranged from 4 to 15 years. Understory environments were described in terms of sunlight,...
