Mechanisms of Competition Between Douglas‐Fir and Red Alder Seedlings
Mechanisms of interactions between Douglas-fir (Pseudotsuga menziesii) and red alder (Alnus rubra) seedlings were assessed in experimentally manipulated stands. The density of each species was variedExpand

Effects of species mixtures on growth and stand development of Douglas-fir and red alder
In the Pacific Northwest, a mixture of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and red alder (Alnus rubra Bong.) often results when red alder regenerates naturally in planted conifer sta...
