Paperback. Condizione: New. Print on Demand. This book focuses on the effects of initial spacing and early thinning on the development of Douglas-fir stands. The author presents the results of a 41-year study conducted on a site IV alluvial flat in the Wind River area near Carson, Washington. The study involved planting Douglas-fir seedlings at various spacings and measuring their growth and yield over time. The book discusses the impact of spacing on basal area, cubic volume, merchantable volume, mortality, and damage. It also examines the development of individual trees in terms of diameter and height growth. The author's findings challenge widely accepted hypotheses and support an increasing body of evidence that maximum production on low site-quality land may be attained through wider spacing of trees. The book provides valuable insights for forest managers interested in maximizing timber production while maintaining stand health and quality.
