Quicker/Cheaper Stand Assessments
In October 1999 I began giving talks and workshops on more efficient timber
stand assessments for Lake States forestry practice. Materials from those
presentations will be made available here as I find the time. To begin with I am
making available for download, three simple Microsoft Excel workbooks that
implement single phase, two phase, and the Big BAF sampling methods. The
worksheets are provided "as is" with no warranty by the author or the University
of Minnesota as to accuracy or usability. No documentation is available at the
moment nor can I answer questions about the worksheets. They simply illustrate
the methods and show that generic software can do a very adequate job of
summarizing cruise data.

I refer to USDA Technical Bulletin 1104 repeatedly in the workshops. A reproduction of that bulletin is available in PDF format here (1.4MB).
I have put together a PowerPoint slide show to illustrate how the mirage and walk-through methods of boundary overlap correction work. The slides are animated so require Internet Explorer to view. Slides 2 and 4 are animated; when the slide is displayed, click on the slide to move through the animation (total of five times).
