Abstract

The influence of planting espacement on the growth and wood properties of Sitka spruce has become a subject of much interest in Ireland. Initial espacement has increased gradually and nowadays plant density is normally about 2000-2500 plants per hectare. Wider planting espacement is attractive because it postpones early thinning and results in bigger poles at first thinning. Wide initial espacement plus fertiliser application has resulted in faster grown Sitka spruce trees. Many foresters are concerned that the wood produced by these trees may be so low in wood density as to make it too weak for many load bearing uses...
