What is ArboTag?

ArboTag is a tag system for identifying trees, consisting of a label, a nail, a special hammer and a magazine. The tag is fixed to the tree in such a way, so as to prevent being covered over and concealed by the bark. Tags move along the nail as the tree grows and are eventually expelled without causing damage to the bark. This ensures that the label remains visible for many years.

ArboTag can be applied quickly and doesn't cause delays in workflows. Excellent durability of the label and the clear visibility of the number and text ensure that the label can be easily read, even after many years. Thanks to ArboTag, urban tree inventories can be efficiently marked, making periodic monitoring and maintenance activities easy.

Tag “Grows with the tree”
