The respacing experiment was set-up to establish the effects on growth and survival different respacing treatments would have on Sitka spruce natural regeneration. Two one hectare plots were established, with each of these being split further into 0.25 ha plots where each of the four respacing treatments would occur. During 2006 the following respacing treatments were carried out:
In all respacing treatments tree selection was based on both position and quality of the stem.
Plots have been sampled in each of the respacing treatments and have been sampled annually since 2009. Within each of these plots height, diameter, leader and lateral length were recorded. In addition whether a tree is missing or has died has been assessed.
Results from this study will help inform the management of natural regeneration occurring inconinuous cover forestry (CCF)areas.
