Project Description:
(Up to 250 words)
Each year Ouray NWR has an aggressive invasive weed control program using a crew of volunteers and seasonals. With our wetland and riparian areas dependent on high spring river flows that is loaded with weed seeds, invasive weeds will be an adherent problem. But many wetland impoundments and adjacent uplands where weeds have spread have already been reclaimed from severe infestations. The Refuge is committed to maintaining those wetlands and uplands already controlled from weeds and to continue to restore additional wetland, riparian and upland areas. There are several species of established weeds on the Refuge. Weed test plots were established several years ago to test various chemicals, rates, and treatment types on target weeds and native vegetation. Those plots continue to be maintained.

Describe the type of work the volunteers performed. (Up to 150 words)
SCA continues to be an intregal part of our weed control team. In 2010, the weed crew contained two volunteers from SCA and will total over 1,500 hours. The SCA volunteers along with the weed crew had a very successful year with control of perennial pepperweed, saltcedar, Russian olive, Canada thistle, and bull thistle. A new method of removal of Russian olive was instigated by one of our SCA interns with use of a weed wrench to remove smaller Russian olives without any chemical control. The crew also assisted with continued collection of data on test plots and installation of a very intense grassland restoration study.
Total Number of Volunteers: 2
Total Number of Volunteer Hours: 1,555

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).
With these volunteers we were able to maintain control of perennial pepperweed in all our areas of prior treatment and expand into new areas. Bull thistle control Refuge-wide was very successful. Our Canada thistle efforts have been re-vamped upon completion of a Refuge-wide inventory and we continue to make progress. Our SCA interns were extremely instrumental in expansion of Russian olive control covering hundreds of acres. Saltcedar control has been very successful and great strides have been made. Russian knapweed control is gaining momentum. All areas of weeds treated are mapped using GPS and GIS systems along with data collected at each site to track treatments.
Number of Acres Treated: 300
Number of Acres Inventoried and/or Mapped: 440
Number of Acres Restored: 200

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 had invasives weeds controlled and to continue to reclaim additional areas.
