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.



  • over 30 members
  • out of 9 countries
  • since 2010
  • regular workshops
  • and membership meetings
  • lively exchange

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.
