A new multi-level parking structure at the corner of Helen St. and Highland Avenue might have destroyed a large Hackberry tree (Celtis reticulata) located in a private yard at 1409 E. Helen.

In response to some concern from members of the North University neighborhood, the Campus Arboretum began the process of assessing the tree, evaluating its chance of survival if moved, and advocating for its relocation north onto the same block of Mabel. The tree has a spread of 46 ft, a circumference of (two trunks averaged) of 4.5 feet, and is 32 ft tall.

Using methods detailed in our Tree Evaluation document, several Certified Arborists on staff at the University of Arizona determined the tree’s dollar value of over $16,000 prior to transplanting.

In June 2004, the tree was successfully moved by Civano Nursery.
