Current Responsibilities with the Team

Develop volume and value analysis prediction equations. Use SAS to organize data and create regression prediction equations and reports from recent and/or historical research data. Examples of recent work follow: 

Explore methods of using a sawing simulation program called Autosaw to simulate lumber volume and grade yield from logs. The program's input consists of data files that are numeric descriptions of the shape of sample logs and also contain the size and orientation of knots in the logs. Batches of up to 99 logs can be sawn to produce a variety of product sizes. Examination of early results of sawing 1600 logs from simulated pruned Douglas fir and western hemlock butt logs is currently under way.

I'm also involved in a study to determine the suitability of using retired western red cedar power transmission poles for second time around uses. This change in disposal policy would provide an alternative to the present practice of depositing them in landfills, and also develop some income. Products being explored are sawn or split rail fencing, boards or square posts. Initial results show used poles are suitable for producing No. 2 and better 6 X 6 posts or 1 X 12 rough sawn boards.



I attended two years of college at both South Dakota State University, Brookings, and University of Montana, Missoula, Montana. I graduated from U. of M. in 1977 with a Bachelor of Science degree in Forest Resource Management. 


Professional Experience

Forester 11/87 to present
Ecologically Sustainable Production of Forest Resources, as a forester responsible for programmer/analyst work, sample setup and data collection. Recent studies have been conducted to reveal optimum uses for trees from small diameter and/or high population stands. Management trends can take advantage of the extraordinarily high-value properties of small diameter trees that have replaced the resource that made up the original land base in the West. Trees from small diameter, densely stocked stands yield wood with uniquely different qualities. The trees yield wood with tight growth rings and small knots.

Forest technician 7/78 to 11/87
Involved in leading field activities and recovery study data collection in all of its forms for forest products recovery studies based in the Western states. In charge of the sampling crew doing a damage assessment survey following the 1980 eruption on Mt. St. Helens.


Work Experience Prior to joining the Team

I worked in a Midwestern states retail lumber and building materials store for 8 years. This job provided me with an education in building plans and materials lists estimates, and during the early years while the job actually involved handling wood, received an exposure to the effects of visual lumber defects on straightness and strength characteristics. Contractors in the home improvement and construction trades were always ready to impart their knowledge of 'how to' skills to a young kid. I then used this newfound knowledge to instruct homeowner customers in their projects.
