DescriptionTree numbers, height, and volume were determined in six 63- to 66-year-old plantations of coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) in northwest Washington. These stands resulted from the first extensive plantings of this species in the Pacific Northwest. Data from 0.25-acre plots in these plantations were compared to those from matched plots in adjacent, naturally regenerated stands with the same history of logging, wildfire, and absence of further silviculture after regeneration. Planting resulted in well-stocked Douglas-fir stands with volunteers of other tree species. Natural seeding resulted in similarly stocked stands of western hemlock (Tsuga heterophylla (Raf.) Sarg.) with Douglas-fir in the dominant crown class. Average live volume was similar in both stand types; only the proportion by species differed. Mean annual rate of volume growth since planting averaged 208 cubic feet per acre, which averaged 2 percent more than in adjacent natural stands.
