The Tree-Ring Society is an international scientific association dedicated to tree-ring research and education. 

Goals of the Society are:

  • To promote tree-ring research to the global scientific community
  • To support the organization of symposia, conferences, and workshops on all aspects of tree-ring research
  • To publish results of tree-ring studies
  • To disseminate knowledge of tree-ring research to other disciplines and to the public
  • To provide a forum for communication for dendrochronologists from around the world

The Tree-Ring Society offers a multiple membership levels.  This includes 50% discount on membership fees to students, retirees, and colleagues in lower-income countries with the same rights and privileges as full-rate members.  This list of countries is defined as any lower income category (any below "high"); see the  World Bank income classifications current as of July 2016.

Our journal Tree-Ring Research is in digital-only format.  Members have full password access to all articles.  Please visit the journal pages and consider submitting your tree-ring related papers. We offer authors an open-access option.   

 High resolution versions of past issues  of Tree-Ring Bulletin and Tree-Ring Research from Volume 1 (1934-35) to Volume 62 (2006) are available from the University of Arizona.

The Tree-Ring Society is on Facebook and Twitter. And be sure to join The Tree-Ring Times, a Facebook forum dedicated to disseminating and discussing information, news items, and recent activities and advances in the tree-ring sciences.

The Tree-Ring Society offers a Traveling Dendro Kit for workshops and fieldweeks that provides all the basic equipment for sampling and crossdating.  The kit includes five increment borers, microscope (ten optical plus a digital scope), battery-operated lights, sanding gear, straws, and more, in a hard-sided suitcase that weighs less than 22 kg (50 lbs) to meet most airline check-in baggage requirements. Please contact Peter Brown (pmb at rmtrr dot org) for more details about obtaining the kit for use in your workshop or fieldweek.   


Tree-Ring Research has an impact factor (2015) of 2.565; the 5-year impact factor is 2.220.  

The Tree-Ring Society is now a recognized 501(c)(3) USA nonprofit!  Please watch for more options that US citizens will have to make tax-deductible donations to the TRS.
