VTA-Method
Visual Tree Assessment
according to Prof. Dr. Claus Mattheck

The VTA method is an internationally spread and acknowledgment method for tree inspection, hazard symptoms are construed, defects are confirmed and measured and criteria of failure are assessed. VTA helps to distinguish apparent hazardous trees from those that are really hazardous. This way safe trees are protected.

VTA gives information about the body language and the mechanics of trees and instructs you in the correct use of our test and measuring instruments.

Advantages of the VTA-Method

The VTA method is applied all over the world. The main focus of the VTA method is to understand the body language of trees. Sound or drilling techniques are used only for defect confirmation and surveying. Those who know the body language of trees can distinguish hazard trees from only apparent hazard trees and thus cut fewer trees while increasing traffic safety.

As a result, justified liability claims can be satisfied and unfounded ones averted. The VTA method is thus neither tree-friendly nor tree-hostile. In the event of damage, this method enables a largely fair judgment tobe reached.
