The Ann Arbor Chronicle » Environmental Indicators: Trees:
The city receives exceptional benefits from our trees. A recent analysis of the publicly managed trees (i.e., trees along streets and mowed areas of parks) estimated that they provide $4.6 million in benefits each year. When you factor in the cost for management, the city receives $2.68 in benefits for every $1 it spends on the municipal forestry program. We think that’s a pretty good rate of return.
What are these benefits and how were they calculated?
