WELCOME!
Rocky Mountain Tree-Ring Research
is a nonprofit research organization founded in 1997 by Peter
Brown. We provide expertise in tree-ring
collection, dating, and analysis to answer
a variety of basic and applied questions in fire
and forest history, climatology,
and forest ecology and management. Our
Projects page has more information about current and
recent studies, and recent publications can be found
here.
Our
Basics Pages contain practical information on sampling, sample preparation, and
how to keep your increment borers clean and sharp.
Please browse our
Image
Gallery of tree-ring and other photos related
to dendrochronology. Click on these or any of the other images on the site
for larger versions. Feel free to use any of these
images in non-commercial applications (although I would like
to know where they are used), but contact me before any
commercial use.
OLDLIST is a database of maximum tree ages.
Also have a look at the
Eastern OLDLIST focused on old trees in the eastern US, maintained by
Dr. Neil Pederson at Lamont-Doherty Earth Observatory,
Columbia University.
We also make and sell increment core mounts. We have
two types available, either the
old taller style (~2
cm/3/4" tall) or the
new shorter style (half the size
in height). Both types are sold as 4 foot (1.22m) long
sticks in bundles of 30 or 50 (the
older style is shown in
a bundle of 50 sticks, while the
newer style is shown as two
bundles of 30 each). The older style is US$1.70 per
stick, while the newer style is US$1.40 per stick. Please contact Peter Brown
(pmb at rmtrr dot org) to order, and please specify whether
you want the old (tall) or new (short) style.
