The cooperative agreement between the USDA Forest Service and the Davey Tree Expert Company, which typically funds the delivery of i-Tree, has been indefinitely halted. Without this funding, maintenance for i-Tree will be impacted and the tools could eventually cease to function.

The success of i-Tree has always been driven by the success of the users. If you’ve come to depend on i-Tree for your work, and you believe in the value of these tools, please consider sharing how you rely on i-Tree with the Chief of the USDA Forest Service, your state forester and your congressional representative.
