Evaluating radial compression, color indicator and micro-toughness tests to detect early decay in Douglas-fir

Creator:: Smith, Susan M.
Abstract:: Three methods--radial compression strength, color indicators of decay and micro-toughness, an examination of tracheid fracture patterns, were evaluated for detection of early decay and for application to field use. Three-eighth-inch diameter plugs 3/4-inch long, cut from the sapwood and heartwood of a Douglas-fir pole free of decay, were decayed by...

The effect of forest stand thinning on selected strength and pulp-ing characteristics of Douglas-fir

Creator:: Johnson, Donna A.
Abstract:: The purpose of this study was to determine if amount and kind of thinning had an effect on wood specific gravity, modulus of rupture, modulus of elasticity, growth rate, or pulp yield and kappa number. The study involved 24 1/5-acre plots, three plots in each of eight thinning treatments. The...

Effect of thinning and fertilization on wood properties and intra-ring characteristics in young Douglas-fir

Creator:: Bodner, Josef
Abstract:: The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...

Swinging and processing whole tree, tree length, and log length pieces in a Douglas-fir thinning

Creator:: Burrows, James O.
Abstract:: This paper describes a study done on swinging and processing whole tree, tree length and log length pieces in a smallwood Douglas-fir thinning. Two machines were evaluated, a 70 horsepower rubber tired skidder and a hydraulic loader mounted on a 6 x 4 live tandem truck. The study took place...

The estimation and significance of sapwood basal area in young Douglas-fir stands

Creator:: Dolan, Linda Sutliff
Abstract:: The relationship of sapwood basal area to basal area was examined on stands of young-growth Douglas-fir. Through non-destructive sampling, sapwood basal area was quantified on four different thinning intensities and one control (unthinned) treatment. Emphasis was on testing a sampling method and evaluating variations in the sapwood component as a...

A model of forest nitrogen cycling to assess the effects of management intensity on long-term productivity in Douglas-fir forests of the Pacific Northwest

Creator:: Krzak, Joan
Abstract:: The objective of this study was to assess the effects of forest management intensity on long-term productivity of Pacific Northwest Douglas-fir forests. The components of management intensity included rotation length, timber utilization standard (whole tree or bole only), method of slash treatment (remove/burn or leave) and fertilization practice (urea nitrogen...
