Project Description:
(Up to 250 words)
Buffelgrass and Brassica were recently identified as invasive species of special concern on the KNWR. Two sets of volunteers; totaling 4 people, pulled and bagged over 2660 pounds of Sahara mustard from January to March 2005. They drove most of the refuges 300-mile road network to document Brassica locations by GPS fixes or mileages from refuge junction marker posts. They provided the mapping information to the Region 2 Invasive Species Coordinator April Fletcher. April then met with Refuge volunteers and Refuge Biologist Ron Kearns to plan a strategy for Brassica removal. Three members of the refuge staff helped with Brassica removal for a total of 5 days and were involved with planning the invasive species removal throughout the season. Two volunteers removed about 600 pounds of buffelgrass in the Castle Dome Mountains of KNWR. Approximately 100 volunteer hours were expended in this effort. It appears all the buffelgrass was removed from the refuge in the only know location infested with the grass. Two members of the refuge staff and Leonard LeCaptain, the Exotic Plant Management Team Liaison, helped pull buffelgrass for a total of 2 days.

Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers were responsible for the majority of the accomplishments in control of buffelgrass and Brassica on KNWR during FY 2005. Refuge Hosts, Leroy and Gloria Iverson and Carol and Joe Garland were the lead volunteers in the effort. The volunteers worked on weekends and nights during planning and strategy sessions numerous times with the refuge biologist and once with the Regional Invasive Species Coordinator.
Total Number of Volunteers: 4
Total Number of Volunteer Hours: 448
List both new and existing partnerships utilized in this project. (Up to 150 words).
The Kofa Cooperative Weed Management Area team was involved in planning and documenting the occurrence of invasives on refuge roads and treating infestations of Brassica along road corridors leading to Kofa NWR following the completion of this project to help determine if herbicidal treatment would be more effective that hand pulling. BLM and Yuma Proving Ground (DOD) were partners in this effort as was Arizona Department of Transportation.


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).
Maps were made of areas of Brassica infestations using GPS on and off roads and point-to-point mileages on refuge roads. Over 2660 pounds of Brassica plants were pulled. We weighed each bag and over 2/3's of the bags only included the top portion of the inflorescence and not the weight of the full leafy plant. At least 20 satellite populations were cleared of this invasive as an early response effort to prevent spreading of seed. Over 600 pounds of buffelgrass was removed and thus prevented from seeding.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The Grant Program was the only way we were able to meet the objectives considering our budget limitations. This form is a convenient way to document the project.
