    Information on the regeneration of Douglas-fir, one of the most valuable timber species in the United States, is summarized, from seed production to care of young stands. General recommendations are given to guide the practitioner. Seed production can be increased by applying fertilizer and by stem girdling. To prepare sites for planting, mechanical, burning, chemical or a combination of treatments should be used. All details during each stage of the planting process should be followed. Steps should be taken to control vegetative competition and animal damage to seedlings and young trees. If direct seeding is used, generally accepted practices should be followed. And if natural regeneration is attempted, harvesting should be scheduled to coincide, if possible, with a good seed year.
