A Closer Look At Trees
Recent iTree Ecosystem Analysis Details the Value of Weston's Tree Canopy
The benefits of trees to a community are more than just providing shade and enhancing the look of the area. Trees reduce air pollution, cool the air and aid in reducing surface runoff, one of the main causes of water pollution.
The City of Weston recently underwent a tree inventory, which assessed the vegetation structure, function and value of the trees and shrubs that are located on city property, such as parks, facilities, swales and right of ways. The data from 34,573 trees were analyzed using the i-Tree Eco model developed by the U.S. Forest Service, Northern Research Station. The tree inventory helps the city to identify the value of the urban forest in terms of replacement (structural value), as well as the functional values that the urban forest accomplishes in Weston. Areas such as air pollution removal, carbon storage and sequestration, oxygen production, reduction of surface runoff were analyzed.
The tree canopy is a wise infrastructure investment for cities, as governments look to find ways to prevent climate change and improve public health. Overall, Weston's tree canopy has a structural value of $23.7 million; removes almost 7 tons of air pollution annually (a value of $67.4 thousand); provided surface runoff at a value of $64.6 thousand; and provides a value of $900 thousand in carbon storage.
