Forest Hills Neighborhood Association: Durham Street Tree Inventory/Canopy Analysis
Trees provide a lot to us as residents of Durham. Just what it is they do for us is sometimes hard to assign a value to. This makes it hard to justify spending the money needed to maintain an urban tree canopy, especially when other issues clamor for scarce resources.The good news is that there is a way to estimate the value of an urban forest. Thanks to a partnership between the Davey Resource Group and the US Forest Service, there is a suite of software called i-Tree that works in conjunction with a set of tools developed specifically for inventorying and evaluating the value, condition, and canopy density of an urban forest.
