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.
The partial stages of the VTA-method
Measuring systems for the VTA-Method
-
IML-RESI MD300The IML-RESI MD300 is a driling instrument working purely mechanically that does not record a measurement curve, neither electronically nor mechanically. The user feels the result and can read the penetration depth on the 300 mm scale. Often an abrupt and fast penetration is perceptible when the instrument detects a rot zone. Even the annual rings of conifers can be noticed.

IML-RESI F-Series
The IML-RESI F series is driven by an usual drill and is very easy to handle The instrument is cordless and therefore ideal for difficult operating conditions. The measurement profile is recorded simultaneously to the drilling depth on wax paper strip.

IML-RESI PowerDrill ®
The IML PowerDrill® is equipped with an electronic unit that gives clear support in taking, documenting and evaluating measurements. It can be used wherever reliable and meaningful measurements are required.
