Tree Inventory Services (TIS) From Imagine Grinnell

In 2006 Larissa Mottl spearheaded a collaboration between the Center for Prairie Studies of Grinnell College, the City of Grinnell, and Trees Forever to map and catalog the public street trees and park trees of Grinnell, with funding from Imagine Grinnell. The results of that study were presented in 2011, and from that presentation, a survey of the Grinnell Country Club was commissioned for 2012 and completed by Jordan Scheibel on behalf of Imagine Grinnell. This summer, Imagine Grinnell is excited to announce that the nonprofit will be offering the service annually to area residents and property managers.
