Ash trees are getting infested with bugs and a fungus. We lost our ash in the front yard this year to the fungus--it started dropping entire branches in our yard. When it was cut down we could see the fungus spread all over the rings inside. Yuck. Luckily, Iowa City allows us to plant in the right-of-way (between the sidewalk and the street), which we have to do to replace the tree cause the roots fill the front yard. But we miss our tree. Can you petition them to replace yours? Or just plant your own and see if they notice?
