Project Description:
(Up to 250 words)
Early detection and rapid response of saltcedar and Russian olive establishment within Refuge water delivery canals. Removal and treatment of cut saltcedar and Russian olive within water delivery canals cannot be accomplished with customary heavy equipment and mowers. The steep canal banks must be cleared and treated by hand. This project needs a large group of people willing to do intensive manual labor.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
In 2007, we had two volunteers, one summer SCA volunteer that worked 450 hours and a very willing volunteer that approached us for the opportunity. They were involved in a variety of invasive weed control projects, including control and removal of saltcedar and Russian olive, perennial pepperweed, and Russian knapweed, assisted with many test vegetation test plots for perennial pepperweed, saltcedar and Russian knapweed, and assisted with completion of the Refuge wide weed inventory.

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).
Of the 1.7 miles of canal that we desire to clear of saltcedar and Russian olive, about 1.25 has been cut. Funding for this project was not received in 2007 so it could not be a huge priority. In addition, access to personnel that could use a chain saw was very limited in 2007. However, some additional areas were controlled and the entire canal that had been treated in the past was spot treated where needed. In addition, with the help of the volunteers a total of 252 acres of invasive weeds were controlled in 2007 which included saltcedar, Russian olive, perennial pepperweed, Russian knapweed, Canada thistle, and bull thistle. In 2005, over 110 acres of saltcedar were treated. By 2007, retreatment of those same areas was less than 60 acres with the density of remaining saltcedar vastly reduced. Also in 2007, over 2,400 acres were inventoried for weed investations to complete the Refuge wide inventory with the help of our volunteers. Eighteen test plots for saltcedar, perennial pepperweed, or Russian knapweed control were monitored which provided valuable information on the most effective control techniques.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program is essential for us to continue our aggressive invasive weed program. Several wetlands have been reclaimed and work has continued on others. We are in the process of restoring a 11.5 acre upland site that has been reseeded to native grasses but was once almost solid weeds.
