KNOTS IN SECOND-GROWTH DOUGLAS-FIR By BENSON H. PAUL Silviculturist The total area of second-growth Douglas-fir in the states of Oregon and Washington i$ estimated at approximately 5 million acres. In these states, /4 million acres, largely from this area, have been designated as "tree farms.", A study of the quality of second-growth. show all steps. Relative density was determined for one sample of second-growth Douglas fir 2 x 4s with a low percentage of juvenile wood and another sample with a moderate percentage of juvenile wood, resulting in the following data ("Bending Strength and Stiffness of Second-Growth Douglas Fir Dimension Lumber," Forest Products J., ): Estimate the difference between true average densities for .
Second growth Douglas Fir Reverting to Basics 🌲 - Big Wood demands an understanding of the basics. Douglas fir is an iconic wood for period homes and represents an important era in American history. Douglas fir was a popular choice for homes built in the late 19 th century and the first half of the 20 th century. Its warm amber color tones, distinctive grain patterns, and high strength-to-weight ratio contributed to this popularity.

With chapters on the roles these forests play in carbon and nutrient cycling, sustaining biodiversity, providing timber and non-timber products, and integrated agriculture, Second Growth not only offers a thorough and wide-ranging overview of successional and restoration pathways, but also underscores the need to conserve, and further study, regenerating tropical forests in an attempt to inspire a new age Missing: Douglas-fir.
stars. Second Growth: A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest, until a long enough period has passed so that the effects of the disturbance are no longer evident.

Re: Douglas Fir Lumber - old growth vs. second growth. Hey, here's a thought. Perhaps the biggest reason for old growth fir usually being more rot resistant is that it has a higher proportion of the more dense and much les absorbent late wood.
It just won't hold as much water so it dries out sooner after a soaking. ""Second Growth" is a creation of remarkable penetration and skill.
Its small, accurate touches build up to a full and firm whole. Its objectivity, its air of knowledge and judgment, are accompanied by an almost lyrical, delicately restrained tenderness.
Its prose is disciplined, sensitive and luminous."- /5(4).
