Abstract

Through an application of an urban forest analysis tool, i-Tree Eco to street trees in Kawasaki ward of Kawasaki city, we evaluated the analysis results and their applications to urban forest management jobs. By customizing the models and parameters, and employing freely available data as input data, ecosystem services provided by street trees including carbon storage and sequestration, building cooling / heating use change, air pollutant removal and associated adverse health mitigation, avoided runoff were quantified. As a reference value, their total annual monetary values were estimated to be 5.3 million Yen.
