Tree expert or tree technical advisor has knowledge in many areas


Sometimes people think “Oops, this tree is hanging crooked, that's dangerous”. But that's not why. It is not what is often told about trees that it is all correct.

Our tree technical advisor or tree expert is trained in the field of trees and everything related to them. Both in the field of physiological processes that take place in a tree. As mechanical processes that affect a tree. Also about the quality of the growing area. And all the soil life that takes place there. And how these affect the life and well-being of the tree are part of his skills.

Knowledge about the different life stages of a tree is also part of his knowledge. And the developments that take place in the crown during these different phases of life. In other words, anything crown architecture regarding.

Because these things are important to be able to judge whether the condition and vitality of the tree deviate from normal or not at all. Below is an example.



Example life stage of tree that does not match its characteristics

Why a tree expert has good knowledge about the life stages of a tree and the crown architecture of trees needs, the following example clarifies.

If a young tree of 10 years old already has veteran characteristics, such as dying branches and hollows, which is perfect for a young tree. Then his condition is not good. And it does not correspond to the condition you would normally expect from a young tree. The young tree then has the characteristics of a tree in its final phase. As a tree technical advisor, you know that the young tree has only limited life expectancies.

On the other hand, like an old tree of 200 years, in addition to some decay and cavities, it is also young orthotropic water shoots (young, upright shoots), it is clear that vital parts are still present. And the tree therefore still has future prospects. Here, a tree technical advisor knows that it is a vital veteran tree that can be preserved for years to come, provided that it is properly managed.

It may be short and quick. But it gives an idea of ​​why this knowledge is so important to provide the right tree expert advice.

Fungi, mushrooms and soil life


In addition to physiological and mechanical processes that take place in trees, our tree expert or tree technical advisor knows that fungi and mushrooms cannot be separated from each other. And how important soil life is.

The presence of fungi on and around a tree tells a lot about the tree. Some mushrooms are parasitic fungi and they indicate accelerated deterioration of the tree. Others are mycorrhiza-forming symbionts and support the trees in their growth, well-being and defense against attackers.

The soil itself is teeming with saprophytes, fungi that decompose wood. And with their fungal threads (or hyphae) they supply the trees with moisture and nutrients through their roots. These fungi are part of the soil food web. Which also includes bacteria and microbes. They are attracted to the substances that the tree roots secrete.

Because the soil life and the soil food web are so important for a tree, a tree technical advisor also recognizes soil disturbances. Such as soil compaction, wetting, lack of oxygen or structural problems in the soil. Because these disturbances destroy the soil food web. And therefore have a very bad effect on the growing conditions of trees. They threaten the trees and can even cause them to die.

Tree safety is a priority for our tree technical advisor


If you have questions about the safety of a tree, you have certainly come to the right place. Tree safety is the issue that always comes first. You always want to prevent an accident with a tree. So that there is never any damage. Nor do people get involved.

A tree technical advisor inspects trees on many parameters. According to the VTA methodology and will judge whether or not a tree exhibits mechanical or physiological defects. This allows the tree to be assessed for safety. And whether the tree could cause damage in the near future or not.

A tree technical advisor also takes into account the hazards in the area surrounding the tree. It is clear that a defective tree in the middle of a forest, where there is no footpath nearby, represents a much smaller risk of accidents than the same tree in the middle of a busy village square.



Assistance with legal files, mediation discussions, disputes and lawsuits


Hopefully, of course, it never has to get to that point. But if there are disagreements, it is very important that correct information is provided in the file. That makes it more acceptable, plausible and predictable for all parties involved.
