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 now offers a 50% discount on membership fees to colleagues in developing countries with the same rights and privileges as full-rate members. The 50% discount fee also is now available to retired colleagues wherever they are located.  A developing country shall be defined as one with a per capita gross net income of USD$15,000 or less as determined by the World Bank. 

Our journal Tree-Ring Research is now in digital-only format.  Members have full password access to all articles.  Please visit the new journal pages, and consider submitting your tree-ring related papers. We now 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 TDK 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 TDK for use in your workshop or fieldweek.
