Excerpt from First-Year Performance of Douglas-Fir and Noble Fir Outplanted in Large Containers Survival counts and height growth measurements were made in late September 1970. Summarized data were analyzed for each Species by analysis of variance methods appropriate for a randomized block design with treatments arranged in a 2 x 6 factorial. The container effects were isolated in a set of orthogonal contrasts. Standard statistical procedures were used to adjust for the unequal number of trees initially planted per treatment.

Decisions about planting mixtures require an understanding of the survival and growth rates of the different species when grown together at different spacings; too many trees of either species may result in volume loss to overcrowding and mortality. The experiment described in this report examines the effects on growth and development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and western redcedar (Thuja plicata Donn ex D. Don in Lamb) after 14 years when grown at 500, 1000, or 2000 stems per hectare in Douglas-fir-western redcedar mixes of 1:0, 1:1, 1:3, and 0:1. Survival and height, diameter at breast height (dbh), volume, and crown growth were measured.--Document.
