Friends of the Tonto National Forest is a 501(c)3 Non-profit Organization

Please help fund our projects with the Donate button below.  Thanks!

We will restart restoration projects in October!

The Tonto National Forest has completed an environmental analysis to control a list of 68 invasive plants that are either known to grow on the Forest or have been documented nearby and could easily move onto the Forest.  The decision that came from this analysis was to control invasive plants using “integrated vegetation management”, which is a term for the complete toolbox of methods that have been documented to be effective in weed treatment.


Friends of the Tonto NF recognizes the Tonto National Forest’s invasive species management program as an opportunity for us to provide much-needed assistance and funding, and have a positive effect on ecosystems from the Sonoran desert to streamside areas, to Ponderosa Pine communities along the Mogollon Rim.


Friends of the Tonto NF is working with local organizations to plan invasive plant removal projects.  We have completed projects and are planning more with Lost Dutchman State Park, Usery Mountain Regional Park, Superstition Area Land Trust and Superstition High School.  If you have a group that would be interested in making a difference please contact us.
