PROJECT BACKGROUND INFORMATION



Project Title: Tatton Unit- Invasive Plant Early Eradication
Region: 2
Station: Aransas NWR

Project Description:
(Up to 250 words)
The Tatton Unit, at just over 7,000 acres, is the third largest unit of the Aransas NWRC. Primary habitat types within the unit consist of salt marsh, wetland, and coastal prairie. In the past 100 years urban development has significantly reduced coastal habitats. However, invasive plants are also impacting coastal habitats at an alarming rate. Since 2002, several new species of invasive plants have been detected on the Tatton unit. This project provided substantial information on the distribution, density, and composition of the nonnative invasive plants within the Tatton Unit. It also served to control the spread and stop the loss of habitat to invasive species. Currently several invasive species (salt cedar, Johnson grass, and Chinese tallow) have been reported from the unit. In addition, several new invasive species (guinea grass and Brazilian pepper) have begun to be reported from the area. It is anticipated that this project will provide the means of early detection and eradication for these new invaders.

PROJECT RESULTS

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).
During the summer and fall of 2009, the upper one-third of the Tatton unit and portions of the Aransas unit was inventoried, mapped and treated for invasive species. The dominant woody vegetation was Chinese tallow with the dominant grasses being Angleton and King Ranch bluestems. An Aerial survey to detect Chinese tallow was conducted in early November 2009 with over 20 new infestations identified. This project allowed the refuge to train 6 staff and volunteers in invasive plant identification and mapping. Staff were also trained in herbicide use and safety.
Number of Acres Treated: 70
Number of Acres Inventoried and/or Mapped: 2400
Number of Acres Restored: 50
