Trees: essential for the living environment, with attention to potential risks

Trees:
essential for the living environment, with attention to potential risks

Trees are vital for a healthy and liveable environment. However, they can also present risks. Damage to infrastructure, safety risks or maintaining unstable trees can have serious consequences. That is why it is crucial to carefully manage and inspect trees in high-risk locations is crucial. This requires professional knowledge, precision and experience.

With detailed analyses, we provide tailored advice, so that you can act in a well-considered and responsible manner in line with the applicable regulations.

Why a VTA is essential for veteran trees

Why a VTA is essential for veteran trees

Veteran trees are natural monuments, but also complex ecosystems that require special care. A VTA makes it possible to detect risks such as breakage or parasitic infestation at an early stage. This allows us to take targeted, life-prolonging management measures that both preserve biodiversity and ensure safety. In this way, historic trees can be managed sustainably, with respect for their unique ecological value and long lifespan.

The Science behind VTA

The Science behind VTA

Nature follows universal laws: fire rises, water flows downwards, and trees respond to forces in the same way all over the world – consistently and predictably. This makes it possible to assess the stability of trees with a high degree of certainty. The foundation of this method is the axiom of constant stress.

The strength of VTA: scientifically substantiated, legally recognised

The strength of VTA: scientifically substantiated, legally recognised

With more than 35 years of scientific research, the VTA is recognised worldwide as a reliable method for tree assessment. It provides not only precise scientific precision but also a high degree of legal certainty. Whether it concerns identifying defects, determining irreparable damage or providing technical tree advice in legal matters. The VTA offers insight and certainty for both tree professionals and legal authorities.
