Each year Ouray NWR has an aggressive invasive weed control program using a crew of seasonals and volunteers. With our wetlands and riparian areas dependent on high spring river flows, invasive weeds will be an adherent problem. But many wetland impoundments have been reclaimed from severe infestations. Work will continue to maintain those wetlands already controlled of weeds and restore additional wetland, riparian, and adjacent grassland areas. Target weeds that Ouray NWR focuses on are saltcedar, Russian olive, perennial pepperweed, Russian knapweed, and Canada thistle. A new weed, bull thistle was recently discovered and considerable effort will be made to attempt to completely eradicate this weed. Several weed treatment test plots will also be maintained. These plots test chemical varieties, rates, application methods, and effect on target weeds and desirable species to determine the most effective and efficient method of control.

Describe the type of work the volunteers performed. (Up to 150 words)
An ongoing saltcedar removal project was completed in 2008 thanks to a boy scout working towards his Eagle Scout. A 1.7 mile water delivery canal from the hatchery was infested with saltcedar and some Russian olive. These trees had to be removed by hand as they were too big to foliar spray and the banks of the canal too steep for equipment to access. The work needed to be done was very labor intensive, needing a large group to complete with about 1,000 feet of thick saltcedar remaining. The saltcedar removal and treatment was completed in 3 days time with several boy scouts and parents. In addition, in 2008, Ouray NWR was able to hire two SCA interns as part of the weed crew. They have assisted in all aspects of the weed control program making up half of the weed control crew. Our efforts on all weed fronts have been very successful in 2008.

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).
Much has been accomplished in our weed control program. The 1.7 mile hatchery canal has now been completely cleared of saltcedar and Russian olive. The 1 mile center canal in Leota Bottom, and the L-10 and S-4 impoundments have also all been cleared of saltcedar. Only minimal yearly maintenance will be needed. Other large areas that contained saltcedar, Russian olive and perennial pepperweed have also been controlled that included old ditch systems, natural draws, grasslands, and shrub/grasslands. A stretch along the Green River of the Auto Tour route is currently being cleared of saltcedar and Russian olive to allow better visibility of the Green River for visitors. Work will continue in many other high priority areas of the Refuge where much has been done including L-7, L-4, Wyasket Pond, the Parker Tracts, Johnson Bottom, the old hatchery site restoration area, S-5 and S1a. The weed crew also was instrumental in assisting with biological control of saltcedar. In conjunction with the Uintah Basin Cooperative Weed Management Area (UBCWMA), a large beetle collection was completed and the beetles released at Ouray NWR to establish a population of beetles in a different area of the Refuge. The weed crew also assisted UBCWMA in several other weed projects upstream on the Green River of weeds that are not currently on the Refuge. All the weed treatment test plots were monitored with assistance from the weed crew and several new developments of weed control were made.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program is essential for Ouray NWR to continue our aggressive invasive weed control program to maintain those areas that have been cleared of invasive weeds and continue to reclaim additional areas.
