While not Internet-connected, Denver has been maintaining a database of its street trees (the ones between the street and the sidewalk) for many years now: https://data.colorado.gov/Environment/Tree-Inventory-of-Denver-Map/hzmx-2dfk.

It's because trees do not grow naturally in the semi-arid climate. If it were not for human activity, all of Denver would resemble the airport: sweeping plains of rough grasses. If a tree dies, then it's not like a new one is going to grow in its place unless someone actively plants and waters it. So the Denver government keeps track of these things and offers free/low-cost street tree plantings.
