Sonoran Desert Weedwackers

The Sonoran Desert Weedwackers started in 2000 as a small group of committed individuals whose objective was to remove non-native fountain grass and buffelgrass from the washes and roadsides of Tucson Mountain Park, a 27,000 acre Sonoran Desert natural preserve a few miles west of Tucson. Since that time, the Weedwackers have become well-known in the invasive weed management community for their successful removal of tons of invasive grasses from the Tucson Mountain Park. Areas where dense buffelgrass was removed in 2001 now support native grasses and wildflowers.

The Weedwackers are supported by Pima County Natural Resources, Parks and Recreation and the Tucson Chapter of the Arizona Native Plant Society. Members of the group perform monthly surveys of the Park for the presence of invasive buffelgrass and fountain grass, noting which areas need the most attention. Within a week, a larger team of Weedwackers attacks this area with digging bars and 55-gallon trash bags, eradicating the invasive grasses and carrying the bags out to a “victory pile”. The bags are then removed to a landfill.

The teams of local residents often include other community groups, including the Boy Scouts of America, Rotary, college students on break, and Sierra Club service groups. In the last eight years, the Sonoran Desert Weedwackers have removed an estimated 100 tons of invasive grasses, keeping Tucson Mountain Park safer from fire and protecting the unique Sonoran desert plant community. There are now both east side and west side weedwacking groups working every month.

Sonoran Desert Weedwackers in Tucson Mountain Park

The Weedwackers in Tucson Mountain Park work the third Saturday of every month, usually meeting at the Caretaker's House across from the Desert Museum. Pima County staff provide digging bars and gloves; the group is transported to the worksite by a Pima County van. Volunteers learn the difference between native and invasive grasses onsite. Experienced Weedwackers demonstrate the proper digging techniques in the field.

To get involved in Pima or Maricopa County, send a message to the Tucson Mountain Weedwacker volunteer coordinator Marilyn Hanson. Download a brochure which explains more about the Weedwackers' efforts.

Tanque Verde Valley Weedwackers-East side of Tucson

Tanque Verde Weedwackers started eradicating buffelgrass in March 2008. They cleared the area around Pantano and Irvington Roads. They have since moved to Atterbury Wash which is a protected wash at Escalante Road and Sarnoff Road. They work every first Saturday of the month. To join this group in the buffelgrass battle, contact Sally Danielson by email.
