FERIC studied three log-producing harvesting systems to determine their productivities and costs in stands of intolerant hardwoods. The systems differed based on where the processing took place: during felling, at the stump, or at roadside. The system using a roadside processor proved most economical, but the two other systems we observed are also suitable for the highly variable harvesting conditions encountered in hardwood stands. An operation with at-the-stump processing was also studied in stands of tolerant hardwoods, and the results suggest that this operation was less productive and more expensive than the operations in intolerant hardwoods. The low productivity was, however, compensated for by the higher value of the sawlogs and veneer logs that were produced.
