i-Tree delivers current, peer-reviewed tree benefits estimation science from the USDA Forest Service to all types of users with free tools and support.


The trees around you:

remove hazardous pollutants from the air you breathe,

absorb carbon dioxide from the air to store as wood,

and control storm water by intercepting and absorbing rainfall.

Trees provide more than just beauty and shade.

They work hard for all of us, every day!
