Comparison of Seedling Planting Density on Growth of Douglas-fir Seedlings

Purpose

Project is designed to compare two spacing regimens for planting of Douglas-fir seedlings. Clusters of Douglas-fir trees were planted at 25' spacing and compared to a conventional 8'x8' spacing. Interplanting with alder to test soil enrichment effects.
