14th SAG Workshop

 

The 14th Workshop of SAG Baumstatik has take place on 26th of Febraury 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. He is a member of the ISA International Society of Arboriculture (ISA), of the SIA (Società Italiana di Arboricoltura), and of SAG Baumstatik e.V.. He is ISA Certified Arborist, ETT - European Tree Technician, Board Certified Master Arborist (ISA) and TRAQ (Tree Risk Assessment Qualification).
 
The presentation will be held in English language. Translations of questions from English to German or Italian will available upon request.

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.
