The Tree Benefit Calculator allows users to estimate the annual economic and environmental value of individual street trees using inputs of a tree’s location, species and size. It is intended to be simple and accessible and should be considered a starting point for understanding trees’ value in the community, rather than a scientific accounting of precise values. This tool is based on i-Tree’s street tree assessment tool called STREETS, which can be seen at itreetools.org. For more detailed information on urban and community forest assessments, visit the i-Tree website.
