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. 517 3 $aAssessing urban forest effects & values 606 $aUrban forestry$zMinnesota$zMinneapolis$xEvaluation 606 $aTrees in cities$zMinnesota$zMinneapolis 615 0$aUrban forestry$xEvaluation. 615 0$aTrees in cities 701 $aNowak$b David J$g(David John),$f1961-$01387883 712 02$aUnited States.$bForest Service.$bNortheastern Research Station. 801 0$bORE 801 1$bORE 801 2$bGPO 906 $aBOOK 912 $a9910695876803321 996 $aAssessing urban forest effects and values$93448323 997 $aUNINA
