The Tree-Ring Society is a non-profit international scientific association dedicated to global tree-ring research and education. 

Goals of the Society are:

  • To promote tree-ring research and career development for the global dendrochronology community
  • To provide a forum for dendrochronologists to communicate by supporting the regular organization of conferences and workshops all over the world.  
  • To publish results of tree-ring studies in our journal Tree-Ring Research
  • To disseminate knowledge of tree-ring research to other disciplines and to the public

The Tree-Ring Society offers multiple membership levels.  This includes 50% discount on membership fees to students, retirees, and colleagues in lower-income countries.  We use the  World Bank income classifications (current as of July 2016) define countries with lower income category (any below "high").  Membership includes a subscription to Tree-Ring Research, conference information, and conference discounts.   Members vote on the locations of the Ameridendro and WorldDendro conferences.  

Our journal Tree-Ring Research is in digital-only format.  Members have full password access to all articles.  Tree-Ring Research has an impact factor (2015) of 2.565; the 5-year impact factor is 2.220.  Please visit the journal pages and consider submitting your tree-ring related papers. We offer authors an open-access option, with a reduced cost for members.   

 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.  (We are working on getting later volumes online.)

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 the basic equipment for sampling and crossdating.  This kit includes five increment borers, microscope (ten optical plus a digital scope), battery-operated lights, sanding equipment, 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 borrowing the kit for your workshop or fieldweek.
