Agricola 2000 is a reference point for a range of management and maintenance services for parks, gardens and avenue plantation. From plant census to phytosanitary check-ups, Agricola 2000 can provide both Public Authorities and private citizens with professional assistance.
In particular, we point out the importance of tree stability controls also via VTA method. (Visual Tree Assessment). It consists of an instrumental examination of arboreal plants which runs after a visual assessment showed or hinted at structural defects regarding collar, trunk and crown. This way each tree will be assigned a risk class and therefore a degree of danger.
The Visual Tree Assessment (VTA) method is organised into three stages:
- visual inspection of defects and vitality: the inspection is carried out taking into account the morphology, physiology and biomechanical characteristics of the plant;
- defect identification: in some cases a visual assessment must be followed by an instrumental one to evaluate any woody tissue damage (percussion with a traditional hammer and subsequent use of a Resistograph);
- residual wall thickness dimensioning: it quantifies and positions any ‘anomalies’ (wounds, cavities) detected with the instrumental assessment.
