Project Description:
(Up to 250 words)
This project will involve treatment, using integrated pest management (IPM) techniques, of exotic/invasive plant species on Tishomingo National Wildlife Refuge. Target plants include Johnsongrass (Sorghum halepense), Bermudagrass (Cynodon dactylon), sericea lespedeza (Lespedeza cuneata), tamarisks (Tamarix spp.), Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica) and several others as well as the native eastern redcedar (Juniperus virginiana). Each of these exotic species has infested from about 40 to several hundred acres each and redcedar has infested several thousand acres. All of these species aggressively invade the native habitats found on the refuge to the detriment of the native wildlife, including neo-tropical migrant birds. IPM treatments that will be applied include herbicide, prescribed fire, and mechanical treatment as appropriate for each species and will be deployed between late summer and late winter. Also, the volunteers will use GPS and GIS resources to map and track infested areas by species so that we will have a more accurate understanding of the extent of the problem.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Assistance with the American burying beetle survey that was required for using herbicides in an endangered species' range and finding research papers on the internet to be used during the planning process for the Refuge's Integrated Pest Management Plan. Training and certification for chemical use and use of heavy equipment to kill/remove the invasive species has been completed. Training was accomplished on GPS/GIS equipment to be used on the invasives mapping part of the project. And most importantly, the volunteers removed thousands of invasive trees, shrubs and other plants of at least 7 species.
Total Number of Volunteers: 4
Total Number of Volunteer Hours: About 650 and expect about 600 more by completion.
List both new and existing partnerships utilized in this project. (Up to 150 words).
The Student Conservation Association and Americorps were involved in placing the lead Volunteer. The Refuge's Friends Group (TREES) and Pack 100 of Tishomingo's Boy Scout Organization are participating groups. The Oklahoma Department of Wildlife Conservation has contributed to the project and the U. S. Army Corps of Engineers has been consulted. Several other FWS divisions have assisted in this process as well including Ecological Services and Contracting & General Services.


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).
To date, approximately 3 acres of Tree of Heaven, Chinaberry, Privet, Mimosa and redcedar have been cut down and the stumps treated with chemical to prevent re-sprouting. By the end of February, 5 to 10 additional acres will be treated, several hundred acres will be mapped and monitored and the public outreach aspect of the project will be accomplished.
Number of Acres Treated: 3
Number of Acres Inventoried and/or Mapped: 120
Number of Acres Restored: 0


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program is tremendously important to our invasive species eradication activities here at Tishomingo NWR. Without this grant, we could not have made nearly the amount of progress that we did. The only way I can think of to improve it would be to increase the amount of funds and get them to the field earlier in the fiscal year.
