FERIC has developed considerable expertise in the use of onboard computers in forestry transportation operations. This report has been prepared in response to member requests for a concise summary of this knowledge. It presents an overview of the technology, the results of case studies, and implementation advice for those who are interested in adopting the technology.
The optimum moisture content of the raw logs used in the manufacturing of oriented strand board (OSB) may be defined by a minimum requirement for fibre conversion and a maximum that will limit the cost of drying the flakes. This criterion could become the mainstay of an effective raw-log purchasing and inventory management program. However, OSB manufacturers have lacked the technology for monitoring whole-log moisture content. FERIC tested several technologies and identified time domain reflectometry (TDR) as an effective means of sampling the moisture content in a large number of logs.
Until recently, wood product manufacturers have lacked the appropriate technology to manage log inventories based on moisture content. The conventional oven-drying method cannot generate the required amount of data quickly. The Forest Engineering Research Institute of Canada (FERIC) has proven the effectiveness of time domain reflectometry (TDR) as an on-site, nondestructive method for generating moisture readings in standing or felled wood at any stage in the fibre supply chain. Industry implementation of TDR moisture profiling has potential to improve the cost and quality of manufactured wood products. This report summarizes the results of four case studies that address specific issues related to log moisture monitoring.
Test results are presented comparing average cross-track errors obtained in kinematic mode for three GPS receivers of different price ranges using three differential-correction methods under three kinds of forest canopies. Data was collected in all weather over a three-month period and was separated by leaf-on and leaf-off conditions. All receiver/correction configurations provided average cross-track errors suitable for most forestry applications. GPS data collection practices are probably more important than the choice of receiver or correction type.
FPInnovations studied a forest road construction operation in the southern interior of British Columbia in order to provide forest managers with current information about planning and costing. A limited comparison of an alternative construction technique in similar terrain was also conducted. This report presents the second in a series of case studies about evaluating forest road construction techniques in interior British Columbia.
In 1997, FERIC evaluated an endhauling project at a Western Forest Products Limited forest operation on the west coast of Vancouver Island. The study was the first in a series of case studies that describe forest road construction techniques in mountainous terrain, and document productivities and costs of endhauling for a range of material types and site conditions.

The Forest Engineering Research Institute of Canada (FERIC) studied whether Just-In-Time (JIT) concepts were being applied to log delivery procedures within the forest industry in western Canada. This report provides examples of forest companies using JIT concepts in their inventory management procedures, and identifies procedures to assist companies with implementing JIT concepts.
Large seedlings are being planted in Quebec as an alternative to the application of herbicides. To date, several million of these large seedlings have been planted and preliminary results on their survival and growth are promising. FERIC conducted time studies on planting operations during the 1993 and 1994 seasons. Seedlings size, type of packaging and site preparation methods were the main factors that affected planter productivity.
