Abstract
This report summarizes a pilot study that investigated how loads that are applied to skyline systems in second-growth thinning operations affect the line tensions and stress distribution in the backspar. The maximum tension in the skyline occurred when the turn was fully suspended under the carriage. In the backspar that was examined, compression was the critical stress. By recognizing how the critical loads produce stresses on backspars, procedures can be developed that will limit these stresses.

Abstract
Elimination of saw kerf through the compression slicing process has initiated research into the optimization of the compression slicing parameters. Five of these parameters have been selected for study in the 1979-1980 federal fiscal year, through a contract given to Forintek Canada Corp. by Environment Canada. These parameters are the following: 1) Find an alternative to tires or pads for lateral pressuriza tion, 2) Study knife profile to reduce checking damage, 3) Study knife tensioning to reduce checking damage, 4) Study methods of reducing knife friction, 5) Study the dustribution of stresses in the knife when tensioning and slicing. Following is a detailed description of the work done during the 1979-1980 federal fiscal year on each of these compression slicing parameters.

Abstract
Research into the cutting characteristics of bandsaws has shown that the average cutting path of the sawblade is biased to one side of the ideal cut path. It has also been shown that a strong correlation exists between this cutting bias and sawblade deviation. This report is the second on the topic of bandsaw cutting bias and describes the development and mill trials of a PC based, self aligning bandsaw guide system. This system uses data from the sawblade, and programmable logic controllers controlling the bandmill, to monitor bandsaw cutting behaviour and align the guides to minimize the cutting bias and sawblade deviation. The system is shown to effectively reduce sawblade deviation and unscheduled blade changes and compensate for damaged or poorly prepared blades.

Abstract
Reflective tarpaulins are used extensively in Western Canada to protect tree seedlings against solar radiation during transportation and on-site storage prior to planting. This report outlines heat transfer characteristics of new and used reflective tarpaulins, and a FIST (Fiberglass Insulated Seedling Transporter) canopy. Containerized white spruce (Picea glauca (Moench) Voss) seedlings were exposed to heat while stored in boxes under tarpaulins. In a separate laboratory experiment, seedlings were pre-conditioned and exposed to heat. All seedlings were outplanted in nursery plots, and survival and growth were monitored.
