Project Description:
(Up to 250 words)
This project will involve treatment, using integrated pest management (IPM), of exotic, invasive plant species on the Attwater Prairie Chicken National Wildlife Refuge. Target plants include deep-rooted sedge (Cyperus entrerianus), Macartney rose (Rosa bracteata), and Chinese tallow (Sapium sebiferum). All of these species aggressively invade coastal prairie grasslands found on the refuge. It has been estimated that less than 1% of coastal prairie grasslands remain in relatively pristine condition. Populations of endemic grassland birds have declined more in recent history than any other bird group, including neotropical migrants. Properly managed grassland satisfies every known requirement of the critically endangered Attwater's prairie chicken (APC), and is beneficial to numerous migrant grassland birds and resident wildlife species as well. Chemical treatment of deep-rooted sedge will take place in spring and summer. Chemical treatments on other invasives will generally take place in the fall. IPM treatments that will be applied include herbicide, prescribed fire, and mechanical treatment as appropriate for each species.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers scouted the Refuge for infestations of deep-rooted sedge and Macartney rose. Deep-rooted sedge was treated by spot spraying from all terrain vehicles mainly along roadsides. Macartney rose was also spot sprayed using ATVs by selecting patches with heavier infestations of rose.
Total Number of Volunteers: 6
Total Number of Volunteer Hours: 134

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).
All Macartney rose that was sprayed is turning brown. It is still too early to assess the percentage of total kill, but at this time the treatment appears to have been successful. Approximately 90 percent of the deep-rooted sedge sprayed appears to be dead. This is a species that can easily produce over one million seeds per plant. Although the parent plants are dead, we will have to continue to treat seedlings as they emerge.
Number of Acres Treated: 340
Number of Acres Inventoried and/or Mapped:
Number of Acres Restored: 272


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 instrumental in accomplishing the invasive species control objectives for the Refuge. Without the help of volunteers and the aid of the additional monies, we would not be able to treat very many acres for invasives.
