  • Review of the 23rd SAG tree statics workshop - The 23rd workshop of the SAG tree statics expert working group was dedicated to the topic of the structural interaction of trees and retaining walls, which can be quay walls, excavation pit shoring or other walls with one-sided embankment and nearby trees. The workshop took place on 21 March 2025 in Amsterdam. That city has around 600 kilometres of quay walls to maintain along its numerous canals, and is therefore well suited to discussing this topic. The workshop was attended… … Read More

  • 23rd SAG-Workshop - SAVE THE DATE! The 23 rd workshop will take place in Amsterdam on 21st March 2025! The workshop is about tree stability, quay wall stability and possible interactions: the case of Ulmus in Amsterdam. The two go back a long way (Unesco world heritage). In recent years trees are assumed to be a possible threat to the old quay wall constructions because quay walls have collapsed in several places. But is this the case? What can we learn from natural tree… … Read More

The Tree

is a complex biological organism whose functions are often only partially understood. Obviously, we can only promote and deepen this understanding if we adopt a broad interdisciplinary approach. For this purpose, all rationally comprehensible findings and research approaches should be noted and tested impartially for their practical applicability.

The SAG does not only want to use the resources of its members, but also aims for a specialist discussion with all representatives of specialist disciplines outside the SAG. Our work is not aimed at representing the interests of individual research methods and approaches. Existing methods should be discussed, evaluated and, as far as possible, integrated and further developed on the basis of new findings.

 

We

  • out of 9 countries

Expert Skills

The expert working group Baumstatik is an internationally registered and non-profit association.
Our members come from the fields of forestry and engineering, biology, mycology, tree care and horticulture. These skills and experiences flow into an interdisciplinary collaboration.

The members of the disciplinary SAG Baumstatik e.V. have a wealth of experience in the field of tree statics. In addition to the high level of knowledge in the respective subject area, this is based, among other things, on the preparation of several thousand safety assessments on trees, on the basis of statically integrated, injury-free tensile tests. Our expertise is also reflected in the fact that almost all members of the SAG are publicly appointed and sworn in as experts (öbv SV) and thus act as appraisers in court.
