This project attempts to eradicate Chinese tallow trees form a large portion of bottomland hardwood forest. The project site is a satellite unit of the San Bernard NWR.

Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers have the unenviable task of bushwhacking through brier and poison ivy, fighting off mosquitoes, fire ants and bees and sweating out stifling heat and humidity to systematically eradicate Chinese tallow. The method of extermination was a notch and spray technique using Garlon-4 and Arsenal herbicide. This is under the guidance of a refuge employee that is licensed by Texas as non-commercial chemical applicator. This project concluded in spring 2008. The mission was accomplished but Garlon 4 will not be used again due to signs of sensitivity to applicators.

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).
Project success was measured by number of trees chemically treated rather than by acres treated. Once a person got the system down of notching and spraying he or she could potentially take out 300-350 trees in 3 hours. The current total is 3000 trees and will resume in spring 2008. when new foliage emerges. It is projected that in 2 years 90% of Chinese tallow trees will be eradicated from this unit.
Number of Acres Treated: 20
Number of Acres Inventoried and/or Mapped: 20
Number of Acres Restored: 10


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

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
The technique of notching tree bases and spraying into the cut with herbicide is very effective. Heavy vegetation makes carrying a large sprayer exhausting therefore a 32 oz spray bottle was used. When compared to spraying with a backpack sprayer, the spray bottle used less herbicide and allowed the applicator to move through the underbrush more efficiently.
