Abstract
Seed-bearing cones are collected by picking from felled trees, by tree climbing or by helicopter. Aerial collection had the advantages of speed, off-road mobility and free choice of the best trees. FERIC monitored 12 aerial collection operations which used several different devices suspended underneath, and manual clipping from helicopters. This report describes production rates and costs for the different tree species, flying conditions and collection systems.

Abstract
With the help of B.C. manufacturers and users, FERIC conducted an engineering investigation of the boom-chains used in B.C. coastal logging and the factors affecting their operational life. The FERIC report discusses the sorting and cutting of worn chains and recommends specifications for the manufacture of new chains.

Abstract
The cord King FM-50 is a Canadian built firewood processor. The machine under study was processing hardwood tree lengths and tree sections which had been culled from sawlog and veneer logging operations. With approximately 50% of the bolts cut only and 50% having to be split after cutting, net firewood production was in the order of 3.75 full cords per pmh.

Abstract
The S.L.R.-200 is a sliding-boom delimber attachment which uses two sets of delimbing grapples. Each of them can delimb one or more trees at a time and each has its own toping saw. The study concluded that a productivity increase over single head delimbers in the order of 25% to 30% can be expected.

Abstract
This project which was initiated by FERIC describes how a grapple saw was mounted on a Morbark 22 chiparvestor equipped with a sliding boom. The objective was to remove all potential sawlogs from the full trees prior to chipping, thereby improving the profitability of the harvesting operation. It is intended that this method would be used in many areas in stands where the low number of sawlogs and veneer logs cannot justify the expense of an additional man in the crew. Production results, cost/benefit analysis and installation details are given.

Abstract
The Timbco carrier was designed to be a logging machine and is not simply a modified excavator, it incorporates several features which permit its efficient operation in a wider range of terrain and operating conditions than other feller-bunchers presently available. Performance data from four short-term studies are given.

Abstract
Truck-unloading activities were analyzed at 11 coastal sites. Activities which affected other trucks (queuing, binder removal, unloading, on-line trailer hoist) were separated from those not affecting other trucks (yard travel, weighing, fueling, watering, delays, off-line trailer hoist). Combined unloading times varied 8 minutes for the "fastest" site to 31 minutes for the "slowest".
