Seedbed Density Influences Height, Diameter, and Dry Weight of 3-0 Douglas-Fir
Successful reforestation on many sites in the Douglas-fir region requires the planting of large stock, which is usually produced by nursery transplanting. Transplanted seedlings, however, are expensive and it is possible that lower cost 3-0 seedlings could replace them on some sites. This would require growing suitable 3-0 seedlings as a standard nursery practice; yet knowledge for growing 3-0 Douglas-fir seedlings is limited. Past observations suggest that their development is greatly influenced by seedbed density.
