EDF 2022 in Heiligenstadt, Franconian Switzerland, Germany
The 32nd European Dendroecological Fieldweek (EDF) took place in Heiligenstadt in scenic Franconian Switzerland, Germany, from May 29 to June 6, 2022, directly after the TRACE Conference in Erlangen. The event was organized and conducted by K. Treydte & E. Martínez-Sancho (WSL), A. Crivellaro & A. Piermattei (Uni Cambridge), R. Kaczka (Uni Prague), A. Žmegač (TU Munich), and the local team A. Bräuning, M. Häusser & A. Debel (FAU Erlangen).
A diverse group of 29 tree-ring enthusiasts, one baby and two dogs, from 4 continents, >10 countries and various career stages came together for a week to learn about the wide range of tree-ring research, perform case studies, exchange knowledge and personal expertise, and make new friends. A well-equipped field lab allowed exploring various methods of wood surface preparation, high-resolution scanning including the custom-made WSL Skippy device, tree-ring width and blue intensity measurements, and wood anatomical applications. Work on mini research projects in small groups alternated with extended lectures on a wide variety of methodological and scientific topics, and complemented with short presentations of the participants’ research projects. Group projects included 1) Young spruce in a warming climate, 2) Short- and long-term response of beech to drought, 3) Detection of gypsy moth outbreaks on oak, and 4) Wood anatomical characteristics of various plant species. Delicious local food perfectly adapted to any preferences, provided by a local catering service helped keeping energy levels high. During a one-day excursion we visited the prominent medieval castle Greifenstein, hiked through the impressive collapsed karst cave Riesenburg and enjoyed a roof tour at the Dominikaner Church, the largest medieval roof structure in Bamberg, guided by Thomas Eißing, a dendro-archeologist at Uni Bamberg. The week ended with an exciting afternoon dedicated to final group presentations, followed by self-made original Italian pizza à la Crivellaro.
We thank ATR, Ecomatik, Regent Instruments, Rinntech, Sercon and Walesch Electronic for having supported the 32nd EDF.
In memory of Dieter Eckstein
On November 10th 2021, Prof. Dieter Eckstein from Hamburg University, Germany, passed away at the age 82. We are very sad to lose a unique researcher in our working field, and a dear friend to many ATR members.
In our next TRACE 2022 meeting we will reflect on Dieter’s scientific legacy and the important role he played in the establishment of European dendrochronology and in the life of many researchers in our community. In doing so we hope to introduce a great researcher to our younger ATR members.
New tree-ring books!
Recently, two tree-ring related books were published. The beauty of plant anatomy is highlighted in the book “Design over 400 million years. A journey into the extraordinary micro-anatomy of plants” by Fritz H. and Elisabeth Schweingruber (order the book here). Valerie Trouet published a broad-audience book about dendrochronology, climate history, and human history entitled “Tree Story: The History of the World Written in Rings” (order the book here).
Virtual membership meeting
Numerous prizes awarded
During the 2020 virtual membership meeting of ATR, four prizes were awarded. For a video on “Supplying wood for timber-framed houses in Limoges, France” Roberta D’Andrea won the Sercon best video abstract award (watch the video here). The prize for the best M.Sc. thesis was awarded to Duncan Mifsud, who wrote his thesis on “NOx pollution from motor vehicles in Malta as recorded by nitrogen isotope trends in tree rings, foliage, and soils”. In the category of the best Ph.D. thesis, no less than two theses were honoured. Jessie Pearl won the ATR best Ph.D. thesis award for her work on “Reconstructing Late Holocene Climate and Coastal Evolution for the Northeastern United States” whereas Linar Akhmetzyanov won the ‘Fritz H. Schweingruber award’, which was awarded in memory of Fritz Schweingruber, for his thesis entitled “New tools for timber provenancing”.
New sponsor: Sercon!
Early 2020, a multi-year sponsorship agreement was signed with Sercon. The support of this leading company in isotope research will have a significant effect on the ability of ATR to conduct its work, for which we are grateful. The following 3-minute video presents recent advances of Sercon in Laser Ablation IRMS:
TRACE 2020 postponed
In consultation with the local organisers in Lund, Sweden, the ATR board have taken the decision to postpone the TRACE 2020 meeting to 2021 because of Corona virus (Covid-19) outbreak across Europe. We are working closely with the Swedish team to explore alternatives and we will communicate this within the coming weeks.
The local organisers will contact all people who have registered to provide information on refund the registration costs.
On behalf of the ATR board – please stay healthy!
In memory of Fritz Schweingruber
It is with great sadness, that we inform you that Prof. Fritz Hans Schweingruber, one of the founders and honorary president of the Association of Tree-ring Research (ATR) since April 2002, passed away on January 7th, 2020 in Birmensdorf, Switzerland, his family were with him.
Fritz was a pioneer and a worldwide outstanding tree-ring researcher and wood anatomist, as well as an enthusiastic teacher and supervisor. With his curiosity and dedication, Fritz inspired many generations of dendrochronologists and wood anatomists, but also radiated enthusiasm for research far beyond his field of expertise.
We all will miss his kind and genuine spirit.

TRACE 2019: a great success!
With 205 participants from 33 countries we enjoyed a packed and inspiring program with 7 thought provoking keynotes, 67 short and powerful oral presentations, and 120 high-quality posters, some accompanied by original video abstracts. The controversial talk by Martin Wilmking on the Uniformitarian Principle in Dendrochronology challenged concepts of stationarity in data and served to provoke discussion within a divided audience – the last words yet to be spoken on this theme!
For studies on Katmai pale rings and on an extension of the World’s longest tree-ring chronology into the younger Dryas, Patrycja Barnás and Frederic Reining won the best student poster and oral presentation prize. In addition, prizes for the best M.Sc. and Ph.D. thesis written within the field of tree-ring science were granted by ATR. For her dendroecological study comparing growth respones of Picea abies L. Karst and Pinus mugo ssp. mugo at a treeline in Bavaria, Corinna Herrmann received the best M.Sc. thesis award; Jernej Jevšenak won the best Ph.D. thesis for his thesis entitled: “Nonlinear modeling of the relationship between xylem tree-rings and the environment”. Congratulations to all prize winners!

In memory of Hal Frits
Last week, one of the most influential tree-ring researchers of recent times, Prof. Hal Fritts died at the age of 90. Prof. Fritts inspired several generations of dendrochronologists worldwide and he was a driving force in the connection of tree-ring scientists from around the world. Hal worked across dendrochronology, but with specific interests in the development and dissemination of statistical approaches to dendroclimatology. Dedicated to colleagues and students of tree-ring research throughout the world “who share the excitement and challenges of this new scientific field” his book Tree Rings and Climate (1976) remains a core text and represents an enduring legacy almost half a century after it was first published. Tree-Ring Research will always be connected to the name HAL FRITTS.

We are very grateful to our panel of judges who worked so hard throughout the meeting. – The ATR Board.
New ATR board
186 ATR members participated in the ATR elections and the new board was presented at the ATR membership meeting at the TRACE 2018. The new board members have already met and cannot wait to get started realising some exciting ideas.
A brief introduction – ATR board 2018-2020
Dr. Ute Sass-Klaassen, president (Associate professor for wood biology and forest ecology at Wageningen University, The Netherlands) …is eager to continue working with a motivated team to strengthen collaboration between tree-ring researchers but also with colleagues of other disciplines. Motto: The ATR should be a platform for learning, discussion and social interaction!
Prof. Dr. Neil Loader, vice president (Adran Ddaearyddiaeth, Prifysgol Abertawe, D.U. / Department of Geography, Swansea University, U.K.) …will work to support Ute and the Board, and encourage the participation of all our members from across tree-ring research to advance our discipline.
Dr. Ernst van der Maaten, treasurer (Senior scientist and lecturer at TU Dresden, Germany) …is eager to manage the financial affairs of the Association, while ensuring that more financial leeway will be created for supporting and initiating “must attend” ATR activities in future!
Dr. Giovanna Battipaglia, secretary (Senior scientist and assistant professor at University of Campania, Italy) …aims to take care of the Association affairs, to collect inputs from the scientific and public community to solve potential problems and to catch new opportunities for the further development of the ATR!
Dr. Kerstin Treydte, extended board member (Senior researcher at the Swiss Federal Research Institute WSL, Birmensdorf/Switzerland) …is highly motivated to support the great ATR board wherever needed and to open up new opportunities for interdisciplinary exchange between tree-ring people from different countries and different career stages, e.g. at the European Dendroecological Fieldweek and EGU. Motto: „Bring tree-ring research to the people“
Dr. Ryszard Kaczka, extended board member (Researcher at University of Silesia) …aims at including new initiatives to be incorporated in ATR activities, increasing the collaboration between tree-ring scientists and students from East Europe.
Dr. Allan Buras, Junior Researcher Consultant (Research associate, Technical University of Munich, Germany) …aims at fostering knowledge transfer and networking between the scientific offspring and more experienced tree-ring researchers. Motto: ATR is more than the sum of its members (free after Aristoteles).
TRACE 2018 – a splendid event!
More than 160 participants, from over 30 countries – thematic sessions where mainly young and early-career scientists presented exiting research in talks & posters – an invited provocative talk by Rob Wilson requiring us to consider the proposal that “All climate reconstructions are wrong!” – 4 fully-booked workshops given by experts on blue intensity, dendrometer & sapflow measurements, advanced statistics and poster making – a public talk on climate-change effects on forests by Harald Bugmann – a competition to find the champion in tree-ring measuring against the clock (Anja Žmegača from Croatia) – the most inclusive election by ATR members to date and presentation of the new ATR board during ATR membership meeting (more to follow) – excursions to research sites and unique landscapes – the first carbon-neutral ATR event due to a tree-planting campaign, and much, much more…
All activities were perfectly prepared and smoothly managed by the local organising team around Martin Wilmking from Greifswald University! He and his team succeeded to create the perfect environment to stimulate interaction catalysed by excellent food & facilities. Thanks for having us over!
TRACE Volumes 2018 and beyond
The board of the Association for Tree-Ring Research (ATR) has recently discussed the future of the proceedings of the annual TRACE conferences. To keep on publishing the common TRACE-Volumes as an independent series is no longer attractive especially for the young participants of the conference who are under increasing pressure to publish in international ISI listed/peer-reviewed publications.
Given the high quality of oral and poster presentations in recent years from the Association membership including Master- and PhD-students at TRACE conferences, representatives of the ATR-board and the Editor-in-Chief of Dendrochronologia, Paolo Cherubini, have agreed to transfer the TRACE-Volumes to appear annually as special issue of Dendrochronologia.
The new TRACE-Volumes, starting with the proceedings of the TRACE 2018 conference in Greifswald, Germany (23 – 28 April 2018), will be published as full papers (detailed instructions will follow) in the special issues “TRACE 20XX” in Dendrochronologia and will be subject to the same review and editorial scrutiny as standard papers in the Journal.
The members of the ATR-board are expressing their gratitude to Paolo Cherubini for his willingness to support the proceedings of our conference in this way which we hope will not only strengthen the training and visibility of ATR science for early- and established researchers, but strengthen and raise the global profile of Dendrochronologia across the field of tree-ring research.
Workshop ‘Individualistic Growth Response’-network
From 6th to 9th of February 2018, 19 members of the Individualistic Growth Response network (IGR) from 11 countries participated in a workshop held at Wageningen University and Research (WUR), Netherlands. The aim of the workshop was to obtain a first insight into the IGR data-network and outline further research avenues. It was organized by WUR staff members Allan Buras (initiator of IGR) and Ute Sass-Klaassen, and financially supported by the Association for Tree-Ring Research (ATR).
