Webb26 feb. 2014 · Thinnings have a higher harvesting cost per cubic meter than clear-felling if the removed volume and mean size of removed trees are the same. Stand establishment cost in year 0 was 1400 €/ha. The tending cost in year 7 depended on the number and diameter of the removed seedlings, but it was close to 270 €/ha in all cases.

WebbImproved models that include a thinning response will provide forest managers with a better tool for planning stand level management of Norway spruce. The objective of this study was to develop a stand-level model for forecasting growth and yield of thinned and unthinned Norway spruce stands. WebbThe stands were thinned heavily, and the harvested basal area increased with basal area before thinning at sample plot level, which suggest an ambition to reduce the variation. The stands were also monitored using Sentinel-2 satellite data. lower sugar oatmeal raisin cookie recipes

As such, data from long term thinning trials were used to develop a system of stand-level equations for predicting stand volume, basal area, survival, and dominant height.

Each EU was composed of a 2500 m 2 area (50 × 50 m), with a central 400 m 2 circular plot (11.28 m radius) to measure merchantable trees. An unthinned strip of 50 m was left between each EU. lower sugar oatmeal packets
