Six thinning systems were examined to determine their ability to perform second thinnings. Systems using grapple skidders or cable skidders were examined for producing both tree-length and product-length material. Forwarder systems using manual delimbing and bucking or grapple processing options were also examined. Ther performance of each system was measured while conducting 27 simulated second thinning treatments. With grapple skidder and forwarder systems, the effect of felling pattern was also examined. System cost per cord was most strongly influenced by the average stand diameter at brest height (DBH). Bunch size was also a significant factor in explaining the cost of grapple skidder and forwarder systems. Systems utilizing grapple skidders produced the cheapest wood and were tha most efficient users of labor and capital inputs. (Refs. 30).
