Help Saguaro Stop the Spread of Invasive Species

Saguaro National Park offers many different kind of opportunities for volunteers to contribute to the management of non-native, invasive species that have made their way into our wilderness. Depending on the season, opportunity events include mapping buffelgrass infestations, participating in the Weed Free Trails program, and joining monthly buffelgrass and fountaingrass pulls.


Volunteer Events with Resource Management

Saguaro National Park seasonally hosts a number of events for volunteers to join us in working to fight back against invasive species in the park. These events and dates vary depending on the season. To see a full list of events held during this current season, check out our volunteer event schedule.

Weed Free Trails

Hike the trails and help the park! The goal of the Weed Free Trails program is to hike Saguaro National Park's trail network while eradicating non-native, invasive plants that threaten the native ecosystem. Volunteer Weed Free Trail monitors will hike and examine trail segments a minimum of three times per year. This monitoring is done independently and on a very flexible schedule.

The Weed Free Trails program is a great way to get involved with the parks efforts and hone a variety of skills such as:

  • Plant identification
  • GPS navigation
  • Outreach
  • Cultural site recognition
  • Park radio communication
  • Safe hiking principles

Orientations are held periodically. Contact our invasives coordinator at if you are interested or have any questions regarding the Weed Free Trails program.

Do Your Part in the Park

In many cases, invasive species are spread by humans and the dirt and seeds of our hiking boots! Boot brushing stations are gaining popularity throughout different parks and trail systems to help stop the spread of invasive species. Saguaro is working to put these posts at all major trailheads throughout the park in order to better manage what gets tracked in and out of the trails. Learn more about boot brush stations.

Boot Brushes at Saguaro

If you see a boot brush station, use it!

In the Rincon Mountain District of the park, there is a boot brush station at the Broadway trailhead located at the eastern end of Broadway Boulevard and more to be installed in the near future, so keep an eye out.

In the Tucson Mountain District, you can find a boot brush station at all major trailheads.
