Overview

In 2011, the City of Grinnell, in collaboration with Imagine Grinnell and Grinnell College, undertook a project to map and inventory Grinnell's street trees. The goals of this project were:

• assist the City of Grinnell in planning for annual and long-term maintenance
• assist with planning for an inevitable emerald ash borer infestation, including establishment of a citizen monitoring program
• increase public awareness of the values of Grinnell's street trees
