Abstract:An elemental time study was designed and used in a comprehensive investigation of grapple yarding productivity in coastal British Columbia. Data were collected using hand-held computers and processed through a series of editing and auditing programs prior to analysis. A comprehensive statistical analysis was applied to the data including fitting regression equations, stratification and hypothesis testing. The findings include a library of production equations suitable for estimating productive and total cycle times for a wide range of machines and operating conditions. West. J. Appl. For. 6(1):7-10.

- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
