Doctorarbol is based on the Visual evaluation of woodland (EVA) system derived from the VTA system that described Claus Mattheck in the early 90s.
The system is based on the valuation of the visible structures of the tree to determine its internal State both referred to its physiological aspect as a mechanic.
On the base system developed by Mattheck added information and techniques of other researchers as Ted Green (relations tree fungus) Francis Schwarze (relations tree fungus) Francis Halle and Pierre Raimbault (tree structure), Wessolly (static and aerodynamic) in addition to our own research, insights and experience.
He is currently the only Spanish company that traction Test, carried out for the study of the risk of tipping of the trees through the Dynatim system
Specifically in the visual assessment are valued variables such as:
- Leaf density, height and distribution of leaf mass, measures and coloration
Structure of branches and shoots, processes of growth or retrenchment
- Wood's reaction, excessive weight or exhibition
- Defects in joints, codominancias
- Typology of the cortex
