Biomechanics and visual inspections of compromised trees

Spectacular tree damage is a challenge for everyone involved. However, if one understands the biomechanical background, it can help in assessing the safety risk, even in difficult cases. The two main factors that can contribute to a tree failing are: external loads that can occur, and the tree’s load-bearing capacity. Both factors can often be estimated without the use of diagnostic instruments.


We use living trees to teach you simple methods of documenting the results of a thorough visual examination. You will try out tools for estimating the residual load-bearing capacity of a compromised tree, and estimation procedures to determine the loads affecting weak points in the tree.



The main course topics are:

  • the biomechanical processes occurring when trees fail
  • factors to consider when assessing fracture and uprooting risk
  • estimating the ability to compensate; assessing the spread of defects in a tree
  • estimating the residual load-bearing capacity of damaged tree sections; documenting potential stress factors
  • the biomechanical assessment of safety risk posed by veteran trees with pronounced defects
  • estimating the residual load-bearing capacity of damaged tree sections; documenting potential stress factors
  • the biomechanical assessment of safety risk posed by old trees with pronounced defects

Advanced tree inspections – stem tomography, TreeCalc, pulling test method

The visual inspection method for tree diagnoses is often supplemented these days by the use of device-based procedures or further assessment methods. Regulations were first published in 2013 in the Tree Assessment Guidelines by the German Landscape Research, Development and Construction Society.


In particular for arborists, public-sector employees and expert assessors, who have perhaps not yet used the methods and devices, the sheer variety can at times seem confusing:

  • When does which device make sense, what predictions do the different methods allow, and what are the limitations of the various methods?
  • According to what principles do the devices function?
  • What does a consultant need to do and what needs to be documented and illustrated?

Different course formats are used to present an overview of non-destructive tree diagnosis and/or to provide more detailed theory and practice of the use of certain methods.

Tree inspection

Qualification training courses for tree inspectors are held on a regular basis in cooperation with the Academy for Landscaping, Weihenstephan. The course consists of three modules corresponding to a 5-day intensive seminar. It is run in collaboration with Michael Schlag´s, tree expert office (Cologne).


Hands-on tree inspector courses are held on a regular basis in cooperation with the Styrian Chamber of Agriculture’s Forestry Training Center Pichl . These courses cover the basics in the following topics::

  • tree statics
  • stability and safety checks
  • biotic and abiotic damage and its effects on stability
  • advanced inspection methods
  • possible maintenance measures and crown support systems
  • legal aspects

Arbostat basics seminar and user training

Evaluating pulling tests using the specially developed Arbostat software (Arbosafe Hard- und Software GmbH) requires a basic knowledge of mechanics and wood physics, a clear understanding of safety appraisal according to engineering principles, plus experience in estimating wind load on trees and their dynamic reactions to it.


The training consists of four units, which are usually held on four consecutive days. Participants must attend the course on all four days in order to acquire the licence to use the Arbostat software. > more information

Tree care and crown supports
Public safety requirements keep leading to the crowns of old trees being cut back considerably. However, due to the reduction in leaf area and the wounds that result from the cuts, the trees can suffer lasting damage.

In many cases, safety can be ensured by the installation of cabling systems, therefore negating any need for damage-causing interventions. In order for crown supports to be a suitable instrument for guaranteeing public safety, however, they must be installed by experts and be properly monitored.

Numerous products with different designs, flexibility and strengths have now been established on the market. Unfortunately, some tree officers and arborists are not completely sure what system or product to choose, how to configure it correctly, at what height to install it, how to choose the strength and, in addition to that, how to properly inspect and maintain the cabling system.

Our courses and individual lectures cover the biomechanical basics of how to professionally install cabling systems to ensure public safety; we also go into the limitations and problems of the current systems. The participants should then be able to not only select and configure suitable cabling systems for individual cases, but also to reliably select and justify, beyond the use of standard table values, the appropriate properties such as flexibility and load-bearing capacity, especially with regard to different safety objectives.

Rigging and rope-climbing techniques
Rigging techniques, i.e. the dismantling of trees using ropes and blocks, have long been used in tree care. During these operations, the tree, industrial ropes, connectors, and pulleys are connected to form a dynamic system that has to bring a falling log, often of considerable weight, safely to the ground.

The dangers of rigging and the associated risks for climbers are markedly greater than with other tree care measures. Since 2006, Andreas Detter has been doing scientific research into the dynamic forces and movements that occur during rigging, the energy conversion, and the necessary safety precautions. The results of the studies, which span a number of years, are presented in mainly one-day courses and illustrated by significant practical examples and in group outdoor experiments.

The course includes:

  • The Concept of Safety Factors
  • Estimating the Weight of Sections
  • Visual Tree Inspection Prior to Rigging
  • Assessing Anchor Point Strength
  • Kinematics of Lowering Logs with Rigging Systems
  • Assessing the Parameters that Determine Forces Generated by Rigging Operations
  • Choosing Suitable Ropes and Slings
  • Strength of Ropes and Slings and Factors Detrimental to them
  • Tree Dynamics in Dismantling, and the Effect on Climbers’ Safety

Wildlife protection in tree care and tree inspection

The protection of our natural environment and the preservation of biodiversity are two of the most important tasks of our time. Since trees are often also the habitats of rare animal species, arboriculture and landscaping can make a significant contribution to their protection; conversely, it can easily come into conflict with legal regulations.


  • So what are the structures that protected species use as habitats?
  • Are there particularly sensitive phases in those species’ life cycles?
  • Which structures should be maintained at all costs?
  • Which possibilities of inspection are there? What can I still judge for myself and when should I consult specialists?
  • When can arborists be held liable or fined?

Together with experts in the field of nature and wildlife conservation, we can offer you advice and recommendations for arboriculture that conform to the relevant protection laws. We can tell you about the living patterns of typical tree inhabitants and the legal regulations governing their protection. We can draw upon our many years of experience to show you where problems lie and offer you solutions to them.

Managing old trees

The handling of very old trees, which play a special role as ancient trees for our cultural heritage and nature conservation, is a unique field of work for specialized arborists and experts. The pioneering work of the Ancient Tree Forum in Great Britain, among other things, is increasingly attracting the attention of the public and groups of experts to this very special type of tree.


Ancient trees, often protected in Germany as natural monuments, require different care than conventional trees. They must be recorded as biological systems and treated according to their particular biological characteristics, which greatly distinguish them from younger trees. The aim is to preserve them for as long as possible.

In various workshops we examine the special biological features of old and slowly declining trees as well as the specific bonds that xylobiontic beetle species have to the special habitats in old trees and their environment.

Consequently, we can present possibilities for practical tree care that were developed for the long-term preservation and care of ancient and other valuable old trees. The techniques include 30-year management plans, and retrenchment pruning that mimics or anticipates the natural ageing processes of trees.
