Centralised processing may be an alternative to skidsite processing for some regions of New Zealand where radiata pine plantations now await harvest. However, a pre-emptive cut will generally be necessary to reduce felled stems to lengths which can be trucked to a central processing yard. There are various strategies for determining where a single pre-emptive cut should be placed. The effect on potential stem value has been compared for samples of trees using the bucking simulation program AVIS. All strategies tested reduced stem value but the amount of loss varied with the strategy chosen and the subsequent cutting pattern used in the yard.
