Interspecific competition in young Douglas-fir plantations of the Oregon coast range

Creator:

Wagner, Robert Gordon

Abstract:

Improving vegetation management decisions in Pacific Northwest forests requires a better understanding of the interactions between planted conifers and associated vegetation. A practical index of interspecific competition, and quantitative models predicting conifer performance from such an index are particularly needed. To meet this need, neighborhood models of interspecific competition were...

Competitive interactions between Douglas-fir and red alder seedlings : growth analysis, resource use, and physiology

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....
