San Francisco urban canopy gets on the map Growth Rings:
Coming soon to a city near you, a Wiki-fied map of every urban street tree.
The San Francisco urban canopy got a lot of national attention last week regarding urbanforestrymap.org, a public forum that allows citizens to contribute and edit detailed information about the trees in their community.
Using Google Maps, the Web site provides a street address for every tree that also includes species name, common name, trunk diameter and an estimated yearly ‘eco impact’ registered in a dollar amount.
Angie DiSalvo of Portland Urban Forestry said she has followed this initiative for five years and is curious about the cost-management details.
