Excerpt from Natural Regeneration of Douglas-Fir and Associated Species Using Modified Clear-Cutting Systems in the Oregon Cascades
The staggered-setting clear cut had only 407 Douglas-fir seedlings per acre and 28 percent of the plots stocked with any Species.
Poor stocking is typical of many large clear cuts in this general area. For example, twelve 3 to 5-year-old clear cuts on the experimental forest surveyed in 1956 had an average of only 301 (range 81 to 525) Douglas-fir seed lings per acre. Total plots stocked with any Species averaged 28 (range 11 to 48) percent and plots stocked with Douglas-fir averaged only 24 (range 9 to 36) percent, even though both 1 and 2-year-old seedlings were included in the tally.

Paperback. Condition: New. Print on Demand. This book analyzes the effects of modified cutting methods on the natural regeneration of old-growth Douglas-fir forests. It is a significant contribution to the study of sustainable forestry practices and demonstrates the positive impact of thoughtful logging approaches on forest regeneration. Informed by the author's meticulous research on experimental forest cuttings, the book concludes that modified cuttings â" particularly those that prioritize shade provision and seed dispersal â" can significantly improve the regeneration of Douglas-fir and associated species. The findings provide valuable insights for forest managers and landowners seeking to balance timber harvesting with long-term forest health and productivity.
