Project Description:
(Up to 250 words)
Last year volunteers contributed 387 hours to invasive plant management on the Anahuac National Wildlife Refuge. We want to continue this program and expand 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. This work will be completed by October 2006.
