Project Description:
(Up to 250 words)
Four non-native, invasive species are targeted; Brassica tournefortii, Cynodon dactylon, Pennisetum ciliare, and Salsola iberica. Cynodon, Pennisetum, and Salsola infestations are currently limited to small spot infestations and can be eliminated with repetitive, sustained effort and monitoring. The objective with these species is eradication. Brassica is more widespread but restricted to two main roadsides within the refuge and control is our objective in order to prevent it from encroaching on other areas, particularly a recently burned area where this plant will outcompete annuals should it get there. Fall, winter, and early spring are the best times to treat these infestations, particularly before they seed. Continued monitoring for early detection of other infestations and rapid response to treat these is critical.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers were trained in the phenology of the targetted invasive plants and what to look for. The volunteers surveyed the roadsides as they drove to the sites of the known infestations. Once at the sites, they methodically covered over 100 acres and hand-pulled Russian thistle and Bufflegrass plants, bagged them, and removed them from the site. Due to the remoteness of these areas and the driving time required, the volunteers camped on-site.
Total Number of Volunteers: 8
Total Number of Volunteer Hours: 280
List both new and existing partnerships utilized in this project. (Up to 150 words).
Partners included the Student Conservation Association (volunteers from two different programs) and another refuge volunteer.


Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
Approximately 60ac were surveyed in the area of Big Eye Mine and all Bufflegrass plants were removed by hand. Approx. 13.5 miles of road were surveyed into Redrock Mine area where 40ac were surveyed and approx. 8ac of Russian thistle were treated (hand pulled - 9 large garbage bags were filled). No Sahara mustard was found, although it may be a little early in the season. Herbicides were available, although hand pulling was the preferred and effective method. The volunteer crew is scheduled to return later to chemically treat a known location of a Bermuda grass infestation.
Number of Acres Treated: 8
Number of Acres Inventoried and/or Mapped: 113
Number of Acres Restored: 5


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program is extremely useful as it provides another avenue with which to obtain funds for invasive spp. eradication/control, particularly for EDRR surveys. Because it is carried out by volunteers, it also provides educational opportunties to increase the public's awareness about the negative effects of invasive spp. on the landscape.
