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, paleoclimatology, and forest ecology and management.  Our Projects page has more information about current and recent studies, and recent publications can be found here.

LATEST NEWS 
Just added, a new paper on fire and forest history from Mount Rushmore in South Dakota.

Our Basics Pages are constantly being updated with some 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 forest ecology (added to sporadically).  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. 

Several additions have been made to OLDLIST, the 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 Eastern Kentucky University.
