Friends of the Tonto National Forest –
Our Mission

Friends of the Tonto National Forest is a group of volunteers who assist the Forest in its critical mission of natural and cultural resource and visitor use management. We promote public understanding of the Tonto National Forest’s policies, programs, and projects.

This just in…

The Riparian Photopoint Project is kicking off its 2023 season and needs volunteers. If you like taking photos and hiking in the Tonto, then this project is just for you. No special camera is needed and you do not need a four-wheel drive vehicle to get to most sites. Project details can be found here.

Invasive Plant Management

Our progress from October 2021 through April 3, 2022.

Removal Events

Look what we do at a Removal Event!

Events are planned for every 2nd and 4th Saturday from October through April.

First, to participate in any Invasive Plant Management event, sign a Liability Waiver form. The liability waiver is valid for the season.  Second, it is important that you become familiar with the safety requirements which can be seen here Safety Analysis.

You can easily complete the required registration for the removal events at Removal Event Registration. We meet at different times and locations as shown in the event registration form. Additional dates will be added to the registration form as soon as the locations are determined.

Mapping and Monitoring

Mapping and monitoring is a great way to get outside and explore on your own schedule.  With the addition of the Superstition Fire Burn Area, we are asking for more volunteers to participate in this ongoing activity.  We’ll use ArcGIS Field Maps which is a free app for your smart device.  There are 4 species of non-native plants we’ll be monitoring — fountain grass, buffelgrass, stinknet and Sahara mustard. Depending on the time of year, they are quite easy to learn to recognize.  Since the plants are seasonal, there will be an opportunity and need to cover the same territory multiple times. 

We look forward to seeing you in the fantastic Superstition Mountains!

“Wildflowers and More” by local author Marianne Skov Jensen

A limited number of copies of this beautiful and informative floral photo identification guide, “Wildflowers and More”, were donated to FOTNF by a local author. You may get more information about the book and the author here. Proceeds from sales of the book will go towards the Friends of the Tonto’s Milkweed for Monarchs program.
