For September, we actually planned our 18th SAG workshop in Utrecht, the Netherlands. Due to the general situation caused by the corona pandemic, we unfortunately have to postpone the event to indefinite. We are trying to find an alternative date in 2021.
17th SAG Workshop
17th SAG Workshop
on Monday, November 11th 2019 in Frankfurt a.M.
Topic:
SAG Standards for the Pulling Test Method
– continuing on developing technical standards for pulling tests and their evaluation
This time we would like to continue working on the SAG standard based on our experience and previous workshops. In the second workshop on this topic, the results of the individual working groups will be presented, discussed and further developed. The day will start with the presentations of the working groups. In addition we would like to offer room for any further topics that are not yet part of the standards. Afterwards we will discuss in small groups as well as in the plenary before we are going to coordinate the further work.
We are looking forward to meeting you in Frankfurt.

16th SAG Workshop
16th SAG Workshop
on Monday, 3rd and Tuesday, 4th of June 2019
in Gauting
Topic:
SAG Standards for the Pulling Test Method
– developing technical standards for pulling tests and their evaluation
This time, we want to exclusively focus on what we have already learned from our experience and previous workshops. We would like to use this information together with the work already done so far to get the SAG standards really a big step ahead. Therefore, we would like to use this workshop to put together the frame of the SAG standard and finish the workshop with a draft version of it.
The plan is to work in the full group on Monday and start with presentations on specific topics like safety during pulling tests, generating usable data during the test, evaluating the data and the minimum level of knowledge to be gained in training before starting with pulling tests. Additionally, we would like to see the ethics discussion be continued that has been started in 2010 in Aschaffenburg and become part of the standards.
In the morning of June 4th 2019 the results of the first SAG funded wind tunnel study on the effect of adjacent trees on the wind load will be presented and their application to the evaluation will be discussed. Then we will continue in working groups and have the Annual General Meeting of SAG Baumstatik in the afternoon at 2 pm.

14th SAG Workshop
The 14th Workshop of SAG Baumstatik has take place on 26th of February 2018. In Gauting, almost 40 participants met from 10 countries, from Canada to Croatia, from Britain to Italy.
The focus was on recent findings from research in tree statics at unviversities. Presentations were held with the follwoing contents:
- Winching tests on Poplar trees on water saturated soils (J. Böttcher)
- Winching tests on the stability of dead Spruce trees (R. Schröder)
- Winching tests on the stability of forest Spruce trees (O. Krišāns, Riga)
- The influence of the geometry on tomography (Prof. S. Rust)
- Using infra-red markers for optical monitoring of pulling tests (K. Wiegmann)
- Spectral and wavelet analysis of tilt measurements in natural winds (L. Hoffmann)
- Correlating pulling tests and tilt measurements in natural winds to calibrate wind load assessments (D. Esche, P. Schuhmacher)
The results will be available in a summarized format shortly on this website. We would like to thank everybody for sharing their results and the fruitful discussions.

13th SAG Workshop
on October 9 th 2017 in Ferrara, Italy
Topic:
Tree Architecture and Morphophysiology
The shape of trees is the dynamic result of the continuous interaction of every individual tree with the context, even physical, that surrounds it. Tree architecture is the discipline that, defining the principles underlying such interaction, allows to reconstruct the past of a tree, to understand its present and to predict its future evolution.
Through tree morphophysiology it is also possible to relate the architecture of a tree with its biological and functional characteristics, defining the morphological and anatomical relationships that connect the different parts of it. In this way it is possible, for example, to infer the root system organization from the characteristics of the tree’s canopy.
Similarly, it is possible to identify any energetic, hormonal or structural alterations, because the tree architecture would show the consequences of them, or you can evaluate the importance of some symptoms, such as cavities, depending on the indi-
vidual evolution of a tree.
Although the principles of tree architecture and morphophysiology have been studied for more than thirty years, their use at diagnostic and application levels is still very limited. The presentation, from a practical point of view, intends to contribute to highlight this subject.
Speaker:
Dr Giovanni Morelli, agronomist and arborist, owner of Progetto Verde since 1994, is a consultant in in urban arboriculture, specialized in tree risk and tree stability assessment. He has written numerous articles and he is a lecturer in university courses. He has been speaker at more than 60 national and international conferences or seminars.

12th SAG Workshop
on October 4 th 2016 in Nancy, France
Topic:
Advances in biomechanics and mechanobiology for the diagnostic of urban trees
Over the last 3 decades, the biomechanical inputs for the analysis of urban trees have been largely developed, starting with the seminal works of Lothar Wessolly and Klaus Mattheck. As a consequence, leading experts in the diagnostic of mechanical stability and safety of urban trees are now using techniques of biomechanical engineering such as model of static wind loads on trees and/or static tension-flexion tests.
We would like to make an update and to share ideas with arboriculture experts about novel findings from the biomechanics and mechanobiology research along 3 lines directly related to tree safety: crown reconfiguration in wind, dynamics and compartmentalization of mechanical energy, long term acclimation of trees (see program).
The following exchange between scientists and expert will be on i) how to improve current biomechanical tools for the mechanical analysis of trees and ii) how we may change from punctual diagnosis to longitudinal monitoring and long-term diagnosis.
