Tree Rings in Archaeology, Climatology and Ecology

Welcome to the 2021 TRACE – conference!

Dear tree-ring friends,

It is our pleasure to finally welcome you to the TRACE 2021 – Tree Rings in Archaeology, Climatology and Ecology – conference. It has not been an easy task to prepare for the meeting during this pandemic and constantly changing conditions. But the Swedish team together with the Association for Tree-Ring Research (ATR) decided already in 2020, when the pandemic forced us to cancel the event, that we should give it a second try in 2021 instead. When we realized that the pandemic would retain its grip well into 2021, we went from the idea of a hybrid conference to an event completely online. So, this is the first TRACE meeting to be completely virtual. It is indeed sad not to meet face to face, but at the same time it is very climate-friendly with a small carbon footprint, and likely the way many meetings will be conducted in the future.

We hope that TRACE 2021 will be an opportunity to exchange knowledge and experience in contemporary key aspects of tree-ring science. The conference aims at providing a forum for scientist and students that use tree rings as a proxy of climatological, environmental, and cultural heritage studies. In this book of abstracts, a wide range of contemporary tree-ring research from all around the world is presented. These address methodological issues in cross disciplinary and cross-scale studies, while different aspects of tree-ring research ranging from dendroclimatology and forest ecology to tree physiology and dendroarchaeology will be highlighted in four conference sessions.

TRACE 2021 is organized by the three university-based tree-ring laboratories in Sweden linked to Lund University, University of Gothenburg, and Stockholm University, with support from the ATR. We would also like to take the opportunity to thank the organisers of the preconference workshops as well as the sponsors and the financiers who made contributions enabling us to provide this conference free of charge.

We warmly welcome you to TRACE 2021!
