Tree-Ring Society

Tree-Ring Society (TRS) is a non-profit international scientific association dedicated to dendrochronological research and education. 

The goals of TRS are to:

  • Promote tree-ring research and career development for the global dendrochronology community
  • Provide a forum for communication by supporting the regular organization of international conferences, workshops, and fieldweeks.  
  • Publish peer-reviewed dendrochronological studies in our journal Tree-Ring Research
  • Disseminate knowledge about dendrochronology to other disciplines and to the public
