Sommario/riassunto |
|
An analysis of trees in Minneapolis, MN, reveals that the city has about 979,000 trees with canopies that cover 26.4 percent of the area. The most common tree species are green ash, American elm, and boxelder. The urban forest currently stores about 250,000 tons of carbon valued at $4.6 million. In addition, these trees remove about 8,900 tons of carbon per year ($164,000 per year) and trees and shrubs combined remove about 384 tons of air pollution per year ($1.9 million per year). The structural, or compensatory, value is estimated at $756 million. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the Minneapolis area. |
