DescriptionTo better understand the urban forest resource and its numerous values, the U.S. Department of Agriculture Forest Service has initiated a pilot program to sample the urban tree population in Indiana, Wisconsin, and New Jersey and statewide urban street tree populations in Maryland, Wisconsin, and Massachusetts. Results from the pilot study in Indiana revealed that about 92.7 million urban trees exist with a structural value of $55.7 billion. These trees removed about 6,600 metric tons of air pollution in 2000 ($35.4 million value) and store about 8.4 million metric tons of carbon ($170.2 million value).
