Home | Research Programmes | Precision Silviculture Programme | Pruning Workstream
The Pruning workstream aims to deliver prototype pruning tools that improve the safety and productivity of forest pruning operations.
Pruning is reliant on unskilled labour, much of it from the Pacific Islands, and the costs of pruning have risen sharply due to the difficulties in attracting labour to do this physical and hard work. Pruning is a value-add activity that can move radiata pine into higher value markets, but at current costs and returns, coupled with the difficulty of securing labour, the majority of the larger forest owners have stopped pruning. Small-scale forest owners, in general, are continuing to prune, and even if fully mechanised solutions are developed, the scale and the dispersed nature of these forests may mean that fully mechanised solutions are not as cost effective in smaller blocks.
- Quantifying the economics of pruning.
- Improving the efficiency and ergonomics of pruning using new power assist tools.
- Development of partial and full mechanisation and automation for larger scale pruning operations.
- With the development of mechanised pruning there is also the potential to pre-select the trees for pruning (and subsequent thinning), based on remote sensing of tree form and spatial location, and to make this data available as a pruning (and thinning) plan to assist the operator’s decision making or to guide an autonomous machine (Thinning workstream).
