The City painted a dot on a parkway tree, what does it mean?
White (2024 - present) means the tree has been marked for removal. The cause of the removal in this instance varies. The tree could be dead, it could be diseased, it could be hazardous because it has structural problems, or it may just be in general decline with no possibility of recovery. Unfortunately, some of Evanston's biggest trees are at the end of their natural lifespans and are dying of old age.
A horizontal line (in any color) means we caught Dutch elm disease early, and the section of the elm that was exhibiting the symptoms has been removed. There is better than a 50/50 chance of survival of these trees that have had this work done.
Green means the elm tree is part of our inoculation program. We inoculate all public elms once every three years to prevent the elms from contracting Dutch elm disease.
