New Forestry Instrument - stem X-sections



For those of you who were not at the Alaska meeting to see it, you
might want to know about a new instrument that Walter Bitterlich has
manufactured.

For details, you can contact:

Dr. Benno Hesske, FOB
Karolingerstrasse 45
Postfach 12
A-5035 Salzburg, Austria

They are the makers of Bitterlich's Relascopes as well.

It works like a pair of dividers with a centeral slide that
measures distance down to the stem from the apex of the
dividers.  Using the measurements taken it then
provides a drawing of the tree cross-section, including any
dips and crevices.

This has been attempted before, with rings put around the stem and
measurements taken from the ring to the stem, but this is a very
simple and portable method for getting an actual stem cross-section.
