Natural Regeneration of Douglas-Fir and Associated Species Using Modified Clear-Cutting Systems in the Oregon Cascades (Classic Reprint) - Softcover

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.
