Your friendly City Forester has mapped each and every one of the public ash trees in Denver. Feel like you missed out on the fun? Well you’re in luck! Now you can join the tree mapping party thanks to an app called Curio.

In many ways, Curio serves as a social network for trees. It gives their human companions the ability to tag a tree on an interactive map, add stories, photos and data about a favorite tree, search for trees within the app and even add tree-based missions for you and your friends to conquer.

Not only are they a lot of fun, apps like Curio also allow us to protect our urban tree canopies through the sharing of valuable data. Be A Smart Ash, and get in on the act!
