i-Tree is a state-of-the-art, peer-reviewed software suite from the USDA Forest Service that provides urban forestry analysis and benefits assessment tools. It's an easy-to-use, computer-based program that allows communities to conduct and analyze a street tree inventory and evaluate current benefits, costs, and management needs. Communities can analyze the economic benefits of their urban forests with Streets (formerly STRATUM), a street tree management and analysis tool for urban forest managers, which quantifies the dollar value of the urban forest’s annual environmental and aesthetic benefits: energy conservation, air quality improvement, CO2 reduction, stormwater control, and increased property value.
