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 facilitate 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


TRS members: Please remember to vote for the three items that are designed to improve services to and the functioning of the Society. These items require multiple changes to the Society’s bylaws (http://www.treeringsociety.org/trsbylaws.htm), requiring a two-thirds approval by those voting. If you need the link to the ballot again, please write trslori [@] gmail.com.  


TRS is soliciting proposals from interested groups to host the 10th International Conference on Dendrochronology (WorldDendro), to be held in 2018. Proposal submissions close 30 Sept 2014.

6th International Geochronology Summer School: Dating Anthropogenic and Natural Changes in a Fragile Alpine Environment, 30 August to 5 September 2014, BergŁn, Switzerland. Topics to be covered in lectures, excursions, and workshops include dating techniques such as numerical methods (radiocarbon, exposure dating with cosmogenic nuclides, OSL, etc.), dendrochronology, ice-core chronologies,
as well as relative methods like soil weathering and Schmidt-hammer technique.


European Dendroecological Fieldweek 2014, 1 to 6 September 2014, Oviedo, Spain. 


EuroDendro2014, 8 to 11 September 2014, Lugo, Spain. Abstract submission is open now, with deadline at the end of May.


14th International course on Wood Anatomy of Tree Rings: Wood Anatomy and Tree-Ring Ecology, 23 to 29 November 2014, Klosters Dorf, Switzerland.


4th International Conference of Asian Dendrochronology Association (ADA2015), 9 to 12 March 2015, Kathmandu, Nepal. There will be also an international workshop and fieldweek prior to the conference from 4 to 8 March 2015. Some post conference tours also will be organized toward different cities of Nepal.


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.


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.


PDFs of papers from Tree-Ring Research Vol 63 (2007), Vol 64 (2008), Vol 65 (2009), Vol 66 (2010), and Vol 67 (2011) are now available on the TRS website. 


A recent paper published in Vol 70, Issue No 2, of Tree-Ring Research reporting on work led by Dario Martin-Benito that dated a ship found at the World Trade Center in New York City has been reported in (among many other places) Yahoo News, The New Yorker, National Geographic News, and even the International Business Times

TRS is offering a "Traveling Dendro Kit" for workshops and fieldweeks to provide all the basic needs for sampling and crossdating.  The TDK includes five increment borers, microscopes (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.   

For questions or comments, contact Peter M. Brown (pmb [at] rmtrr.org)
