Project Title: Inventory and Mapping of Salt Cedar (Tamarix ramos
Region: 2

Project Description:
(Up to 250 words)
Washita NWR has had a growing salt cedar problem for some time. Salt cedar can be seen increasing along the riparian corridors and other areas. At this time the refuge has no idea as to the extent or coverage of salt cedar on the refuge. This project proposes to map the areas where salt cedar is found on the refuge. This mapping will be carried out by the Southwestern Oklahoma State University Biology Club and other volunteers. The refuge has been cooperating with the university for some time on projects such as an extensive plant species list for the refuge and most recently a Johnson grass mapping project which was presented at the Western Society of Weed Sciences in Vancouver, Canada. We are now planning a mapping project for the salt cedar, which is spread out in very dense hard to access areas. To accomplish this task, boats will be needed to access some of these remote locations. Salt cedar will be mapped using GPS technology and converted to GIS format and added to the refuge database. Once mapping is complete, the refuge will determine the best methods to begin controlling this very invasive plant and will then begin with control/eradication measures. Work will begin in the spring/summer of 2005 and will continue while the weather is warm. Mapping will either be completed at this time or will continue the following spring.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Students and other volunteers are mapping the riparian areas of Washita NWR using GPS technology to determine the extent of saltcedar infestation on the refuge. This will lead to a better understanding of the problem and will help when we initiate a removal program.
Total Number of Volunteers: 5
Total Number of Volunteer Hours: 200
List both new and existing partnerships utilized in this project. (Up to 150 words).
Existing partnerships include the Sothwestern Oklahoma State University Biology Club. These are primarily students in an undergraduate biology program that regularly come out to the refuge to volunteer with a variety of projects. Additionally, we have two professors who act as leaders for the students and a retired professor who is a certified master naturalist.


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).
The project is still in the early stages of mapping. The refuge has purchased a Trimble GPS Unit to facilitate the mapping. The students have come out to get a general introduction to GPS mapping and have surveyed the Washita River, the primary riparian habitat on the refuge. Extensive mapping will commence this fall when temperatures drop below their normal 90-100 degrees in the day. Students and professors will use a boat to access the river and map all saltcedar infestations found. Next spring they will start on the other riparian areas of the refuge that are not accessible by boat.

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Very good. However, when you print out a program like this you never get the full text of the blocks that have more text than can fit on the little area provided. It would be helpful to just hit print and have the full text. Also the way it is now about one quarter of a third page is used. It would be nice to keep it to two pages.
