The IWOA organization has started working with the Iowa State Fairgrounds in Des Moines on a Tree ID Project being led by Kevin Karr. The official name is the Interpretive Trail-Iowa State Fair Ground Trees. The first ten trees have been marked with a pedestal that can be read and when scanned by a smart phone will direct you to a web page that will detail characteristics for each individual tree along with a picture of it. A tri-fold map of the trail and the trees along the way is being developed also. This provides a different learning experience.
