Why Use the Tool
The i-Tree suite provides urban and rural forestry analysis and benefits assessment tools. The i-Tree tools can help strengthen forest management and advocacy efforts by quantifying forest structure and the environmental benefits that trees provide. By understanding the local, tangible ecosystem services that trees provide, i-Tree users can link forest management activities with environmental quality and community livability. Whether your interest is a single tree or an entire forest, i-Tree provides baseline data that you can use to demonstrate value and set priorities for more effective decision-making. i-Tree offers a variety of tools depending on your focus, including i-Tree Eco, Canopy, Landscape, Species, Planting, and Hydro. This helpful guide explains when to use each tool.
