    i-Tree ( is a suite of freely-available software tools designed to assess the benefits and values derived from trees and forests. Originally released in 2006 and designed to work in the United States, these tools have expanded globally among professional and non-professional users (e.g., universities, citizens, schools, land managers, foresters) in more than 130 countries. i-Tree was developed through a collaborative public-private partnership and is designed to engage people in assessing and valuing their forest resources, understanding forest risk, and developing sustainable forest management plans to improve environmental quality and human health. These tools can be scaled to assess individual trees or entire forests in both urban and rural areas.
