Abstract
The Forest Engineering Research Institute of Canada (FERIC) conducted field studies involving a compact, track-mounted jaw crusher used to crush rock for new roads and for road rehabilitation work. This report describes the studies, provides productivity and cost information on the use of the crusher, and provides suggestions for implementing this rock crushing technology on forest roads.

Abstract
In order to provide bridge designers with better information, International Forest Products Limited (Interfor) asked the Forest Engineering Resarach Institute of Canada (FERIC) to evaluate the bending strength and stiffness of log stringers used for constructing bridges on forest roads in coastal British Columbia. Given the lack of definitive standards for testing this material, FERIC developed a field-based test procedure and designed a test facility for destructive testing of full-size, whole-log stringers obtained from second-growth stands. Sixteen coastal Douglas-fir and twelve western hemlock logs were tested in 2003. This report describes the test procedure and methods of analysis, presents the log bending strength and stiffness results, and makes recommendations regarding future testing.

Abstract
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.

Abstract
In 1991 and 1993, FERIC studied a long-distance cableway system operating on forest land administered by the Greater Vancouver Water District (GVWD) in southwestern British Columbia. The study provided harvesting productivity and cost information for a long-distance cableway system with 10-t payload capacity. Production functions were dirived to predict system productivity and costs over a range of operating conditions.
