ARBOSTAPP

ARBOSTAPP™ provides arborists and experts with a tool allowing the determination of strength loss due to structural defects in the cross sections of stems and branches and anchorage plate losses in relation to canopy size and expected wind-loads. In addition, the application enables evaluation of load reduction by crown reduction pruning to further achieve higher safety in damaged trees. The inputs are based on the users visual observations rather than diagnostic instruments but enable accurate (if not as precise) estimations of safety which are sufficient for many tree assessment purposes. However, the precision of the evaluation can be increased by putting in results from proper sonic tomography or resistance drilling with density-calibrated devices.

ARBOSTAPP™ is available in 3 versions:

• ARBOSTAPP™ Pro: Define crown and estimate wind load reduction by reduction pruning cuts. Drawing of intact and decayed/missing parts in cross-section and root-plate area for calculating strength loss.
• ARBOSTAPP™ Exp: Define crown and estimate wind load reduction by reduction pruning cuts. Drawing of intact and decayed/missing parts in cross-section and root-plate area for calculating strength loss.
  Modify basic wind and site/terrain parameters. Maturity correction of required shell-wall for estimating acceptable strength-loss level.
• ARBOSTAPP™ Sci: Define crown and estimate wind load reduction by reduction pruning cuts. Drawing of intact and decayed/missing parts in cross-section and root-plate area for calculating strength loss.
  Modify basic wind and site/terrain parameters. Maturity correction of required shell-wall for estimating acceptable strength-loss level.
  Modify specific wind parameter (porosity, topology correction, gust-and resonance factors).
