Book Description
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.

Book Description
Excerpt from A Study of Decay in Douglas Fir in the Pacific Northwest The trees studied were not clear cut from a given area, but average trees both sound and decayed were selected to obtain preliminary information on which an extensive study of decay in Douglas fir could be based. This will be brought out as the discussion proceeds. In all 170 trees were felled, bucked up, split open, and studied. One of these was only 2 inches in diameter breast high, so it was dropped from consideration leaving 169 trees with a total volume of 203, 920 feet board measure and 33 12 cubic feet.
