Project Title: Control and management of deeprooted sedge and other invasive exotic plants on the upper Texas coast
Region: 2

Project Description:
(Up to 250 words)
Last year volunteers contributed 484.5 hours to invasive plant management on Anahuac National Wildlife Refuge. We want to continue this program as well as continue to address a new invasive plant in the area, deep rooted Sedge (Cyperus entrerianus). This new exotic was first detected in the area in the late 1980s and has proven to be a serious problem in coastal grasslands. Deep rooted sedge has moved onto the Refuge and is establishing itself in many upland habitats. Rapid control of this new pest plant is the best strategy. Volunteers will apply herbicides to control deep-rooted sedge and conduct quantitative monitoring to evaluate timing of application. We will also look at the role of fire, with and without herbicide, in controlling this plant. This monitoring will allow us to refine our control techniques for this species. The Nature Conservancys Texas City Preserve is a partner in this control and monitoring effort. Volunteers will conduct similar work on this preserve. Control of deep rooted sedge will benefit The Texas City Preserve and the endangered Attwaters Prairie Chicken (Tympanuchus cupido attwateri). This grant will also support essential ongoing efforts to control Chinese tallow and water hyacinth on Anahuac NWR.

Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers sprayed Chinese tallow, deeprooted sedge and cattail with hand held sprayers and ATV mounted spray rigs. Plots were monitored to evaluate control of deeprooted sedge. A monitoring program was established to evaluate the assess high-priority invasive species on the Refuge. With continued volunteer support, this monitoring program should provide valuable data on the progress of the invasive species program.
Total Number of Volunteers: 5
Total Number of Volunteer Hours: 395.5
List both new and existing partnerships utilized in this project. (Up to 150 words).
This project is a collaboration between Anahuac NWR, Friends of Anahuac Refuge, The Nature Conservancy of Texas, Clear Lake Ecological Services Office, and Stephen F. Austin State University.


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).
This project has allowed us to initiate an invasive species monitoring program on the Refuge. This program will provide quality data on the progress of the invasive species management program utilizing volunteer effort. In addition, the deeprooted sedge control project successfully moves into its second year and aggressive treatment of invasive species continues on the Refuge.

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This grant program makes a CRITICAL contribution to continuing the fight against invasive plants on the refuge.
