Publication of tree inventories

Municipal managers and individuals who own trees in public spaces may publish inventories of their trees as completed by a certified arborist. The owner of the published inventory may choose to make the inventory publicly available and may also control how much information is shared. This website is unique tool for sharing information with the public about tree care in a municipality. Currently it is possible to import inventories which were produced using the MyTrees application.

Tools for planning tree care

Owners of large-scale inventories, such as minucipalities, may find it difficult to inspect each tree every year. This website offers a tool for planning tree care cased in ISAT methodology. This allows the creation of a plan for visiting and inspecting all sites with trees in the span of several years. The plan is created in such a way that the most exposed sites are higher priority. This allows the manager to match available funding with higher concern trees.

Inventory of installed cables and bracing

Tree owners can record cables and bracing systems installed on their trees. Arborist companies can also record this information at time of installation. This website then acts as a notification system to the owner and arborist alerting when inspection is needed and when replacement may be needed. Inspection data can be recorded and stored over the life of the tree and support system.
