About

ArboRefD

Read full description

ArboRefD helps evaluating the breakage safety of trees with localized defects whose trunk still has an intact cross-section higher up. This is one of the practical applications of Allometric Self-Referencing (ASR) for evaluating the breakage and uprooting safety of defective mature trees. To document the results for a specific tree, we recommend saving a screenshot after entering all data in the current version. Additional features are currently being developed for the app. If you buy the app with a one-time purchase and enclose the corresponding app invoice with your next order of a measuring device (ABT, DNT, RES) from RINNTECH, you will receive a discount.

Artenschutzrechtliche Überprüfung – ARÜ – Ihre digitale Lösung für den Artenschutz. Erfassung und Bewertung von Habitatpotential und Habitatstrukuren in mehreren Prüfstufen. VON UND FÜR BAUMEXPERTEN Vor sämtlichen Arbeiten im und am Baum ist ganzjährig eine artenschutzrechtliche Überprüfung (ARÜ) notwendig, welche sicherstellt, dass die Belange des Artenschutzes beachtet werden. Die ARÜ dient schließlich als Dokumentation und Nachweis, dass die gesetzlichen Vorgaben eingehalten worden sind. Als erfahrene Baumexperten haben wir es uns zur Aufgabe gemacht, diesen Prozess zu vereinfachen, um die Arbeit an den Bäumen gewissenhaft und effizient durchzuführen. Daraus ist schließlich die ARÜ.APP entstanden, welche es ermöglicht, die ARÜ auf digitale Weise fachgerecht durchzuführen und als abrechenbare Leistung zu dokumentieren. √ Fachgerechte Dokumentation √ Benutzerfreundliche Bedienung direkt am Baum √ Effizientes Arbeiten ohne Papier und Klemmbrett √ Leistung abrechenbar beim Kunden √ Verknüpfung mit digitalem Baumkataster möglich
