Tree Inventory Project


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
