WebFirst thinning of local Douglas-fir will often be required within 15 to 20 years of planting. If still unthinned at 30 years, the stand may be too stagnant to respond effectively. Crowns … WebLongleaf pine management regimes with either one or two thinning treatments were considered. Two thinning regimes, common in the generally longer longleaf rotations, were included in this analysis. The first thin was a 1-in-5 row per thin from below combination to 80 square feet per acre residual basal area. The second thin was from below to 70

Thinning Pine Plantations: Why, When and How?
Webthin was used if the post-thin stand resulting from the row thin had less than the residual tree target. Product merchantability specifications (table 1), site pre-paration costs, stand management costs, timber source, and mill destinations were held constant for all simulations. Thinning and clear-cutting harvest operations included only WebThe rate of tree growth slows down in most species when the live crown ratio drops below 40%. Trees with crown ratios of 30% and greater often respond well to release (removal of surrounding competing trees), while trees with crown ratios below 30% often respond poorly. These trees may experience thinning shock or sunscald, or grow very slowly. WebThin stands when the BA is equal to or greater than 120 square feet per acre. After thinning for most pine stands, a residual BA of 70 to 90 square feet per acre represents nearly ideal stocking. Young stands must attain minimum merchantable diameters and height to produce enough volume before the first commercial thinning is feasible. cynomolgus monkey bone marrow
