Abstract

i-Tree is a suite of computer software tools developed through a collaborative public-private partnership. These tools are designed to assess and value the urban forest resource, understand forest risk, and develop sustainable forest management plans to improve environmental quality and human health. This report provides details about the underlying methods and calculations of these tools, as well their potential limitations. Also discussed are the history of i-Tree, its future goals, and opportunities to facilitate new science and international collaboration.

This report is a revision to ones previously published in 2020 and 2021. (https://doi.org/10.2737/NRS-GTR-200-2021). It reflects updates to procedures and values.

Document appendixes can be accessed through links in the pdf.
