Successful Natural Regeneration Cuttings in California True Firs

摘要

In stands of mixed white and red fir in northeastern California, cuttings for natural regeneration became well stocked with seedlings within 2 to 5 years after cutting. Seed tree and shelterwood cuttings, clearcut strips not more than 3 chains (60 m) wide, and patches not exceeding 4 chains (80 m) width were studied. Incidence of damage among trees in or adjacent to cuttings was negligible. Law vegetation developed slowly and did not appear to affect seedling survival.
