Tree Rings in Archaeology, Climatology and Ecology

TRACE2020 is postponed to 2021

Dear all, 

In the last weeks and days we have been closely monitoring the development of the Corona virus (COVID-19) outbreak across Europe. The local organisers in Sweden and the ATR board have therefore taken the decision to postpone the TRACE 2020 meeting. Obviously this has been a very difficult decision, but for reasons of personal safety and to minimise financial loss for both delegates and local organisers we believe that this action is necessary. We hope that you understand our decision. At the moment, we are working closely together to explore alternatives for 2020 and we will communicate this within the coming weeks. One very likely option will be to delay the in-person TRACE meeting by a year, if this is possible then we would hope to be able to run the conference and workshops in a similar format.  

Those who have already registered for the conference will soon be contacted by the organizers.

We hope you will understand why we had to take this action. We hope too that you will be interested and able to participate when we meet in person next year at TRACE. We will keep you updated of any further developments.

Welcome to TRACE 2020!

The international conference “TRACE 2020 – Tree Rings in Archaeology, Climatology and Ecology” will bring together scientists and students that use tree rings as archives of environmental, historical, and climatological information. The conference will take place in Lund, Sweden, from May 12-15, 2020, and is preceded by pre-conference workshops and one post-conference excursion.

The conference seeks to build bridges, and facilitate knowledge exchange between the different scientific disciplines working with tree rings. This is reflected in conference sessions with topics ranging from dendroclimatology and forest ecology, to tree physiology and dendroarchaeology.

TRACE 2020 is organized by the tree-ring groups from Lund University (Department of Geology), University of Gothenburg (Gothenburg University Laboratory of Dendrochronology, GULD) and Stockholm University (Department of Physical Geography), in cooperation with the Association for Tree-Ring Research (ATR) http://www.tree-ring.org.

The organizing committee is looking forward to cordially welcoming you in Lund!
