The U.S. Forest Service has hired a guy to walk Detroit’s streets,
recording the location, species, and health of trees on public land.
Chris Kort, of Davey Resource Group, has been at it since March and
has taken inventory of over 13,000 trees.

The Forest Service hopes to use the data to, among other things, learn
more about the spread of the Emerald Ash Borer — an invasive pest
which was introduced to the United States in 2002 via shipping
palettes arriving in Detroit.
