Abstract:: Red alder (Alnus rubra Bong.) seedlings fertilized with NH4NO3 or inoculated with a pure culture Fran/cia and inoculated with live or dead spores of the mycoirhizal fungus Alpova diplophloeus (Zeller & Dodge) Trappe & Smith were grown in a growth chamber or in a greenhouse for six months Frankia inoculation...

Creator:: Cooke, Pamela T.
Abstract:: Allometric equations are useful tools for predicting tree biomass when direct measurements are impractical. Any factor affecting plant growth can be a significant variable in allometric equations. Density and species proportion are spatial variables that influence tree growth and should be considered when developing allometric equations. This consideration is especially...

Creator:: Puettmann, Klaus J.
Abstract:: The increased interest in red alder (Alnus rubra Bong.) management instigated research in growth and yield and stand development of red alder in pure and mixed red alder/Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands. This study had the goa1s of evaluating the accuracy of the currently existing growth and yield tools...

Creator:: Shainsky, Lauri J.
Abstract:: Competitive interactions between Douglas-fir seedlings (Pseudotsuga menziesii), and seedlings of a nitrogen-fixing hardwood associate, red alder (Alnus rubra), were investigated in an addition series experiment. The primary objective of the research was to identify and quantify key processes underlying intra- and interspecific competitive interactions of Douglas-fir and red alder seedlings....

Creator:: Grotta, Amy T.
Abstract:: When Douglas-fir and red alder grow in mixture, interactions between the two species can be competitive, facilitative, or a combination of both over time. A number of factors have recently led to increased interest in managing these two species together for commercial production, and ongoing investigations are yielding important information...
