The international conference TRACE 2020 (Tree rings in Archaeology, Climatology and Ecology), to be held May 12-15, 2020 in Lund, Sweden, aims to build bridges and facilitate knowledge exchange in all contemporary fields of tree-ring science, ranging from dendroclimatology and forest ecology, to physiology and dendroarchaeology. TRACE 2020 (www.trace2020.com) is organized by the tree-ring groups from Lund University, University of Gothenburg and Stockholm University, in cooperation with the Association for Tree-Ring Research (ATR).
 
Realizing an increasing range of applications and interest in the tree ring community to use the Quan-titative Wood Anatomy (QWA) approach, ATR and IAWA are stimulated to constitute an ATR/IAWA Working Group on Quantitative Wood Anatomy together to strengthen exchange of know-how and experiences between tree ring and wood anatomy science. A workshop will be organized to officially launch this working group on 12 May in Lund, just before the TRACE 2020 conference. Details to the program will follow in due time.
