Increment
Borers
The
primary tool of our trade -- although expensive (about $US 320 for a nice
20 inch (ca. 50 cm) borer), you simply can not conduct tree-ring research
without one. If this is too expensive for your class or school, contact
your local forestry department, especially if a university or college is
nearby. The US Forest Service usually has lots of these, as do state
forestry offices. Even Cooperative Extension services of local
universities have these. Usually they will let your class borrow one, or
provide a demonstration.
If
you do invest in one, learn the proper use and care of this instrument!
They are precision instruments and should be cared for their entire lives
- plenty of lubrication, cleaning, and sharpening. If you care for it
properly, it will serve you well year after year in the field. Learn from
an expert if one is nearby - it will save you much time, trouble, and
expense in the long run!
Note:
If you come across any Sandvik or Djos increment borers on your shelves or
in your closet, I will buy them from you at a reasonable price!
