PROJECT BACKGROUND INFORMATION



Project Title: Control of Invasive Species
Region: 2
Station: Santa Ana NWR
Contact Person:
Name and Phone Number
Kim Wahl, 956-784-7580
Project Description:
(Up to 250 words)
Treat annually a minimum for 100 acres of invasive plant species to include follow-up monitoring. Invasive grass species (e.g. guinea grass and bufflegrass), tree species (e.g. salt cedar and Chinese Tallow), and wetland species (e.g. cattail and black mimosa) greatly impact native upland and wetland species on the refuge resulting in loss of productive wildlife habitat. Areas of concern are along trails, wildlife drive, and managed wetlands. Control of invasive grasses near public use roads and trails is needed to prevent wildfires. About 40% of the refuge's 175 acres of wetland impoundments is covered with cattails and other invaisve species. This project will help reduce the coverage of invasive wetland species by 50%. An intern will map invaisve species distribution to help identify primary treatment areas. Service staff and volunteers will apply Service-approved herbicides, conduct mechanical treatments, and conduct follow-up monitoring to evaluate efficacy of treatments.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteer intern obtained pesticide applicator licensing and use chemical control on invasive grasses on 115 acres of high-visitor use areas, included along trails, wildlife tour loop, observation towers, visitor gardens, and parking areas. The volunteer intern also conducted monitoring on invaisve tree species treated the previous year and retreated through chemical methods. New occurences were also mapped out and treated with chemical methods. Other volunteers mechanically removed invasive grasses in parking areas, around Visitor's Center, and in visitor's gardens.
Total Number of Volunteers: 20
Total Number of Volunteer Hours: 580
Partnerships:
List both new and existing partnerships utilized in this project. (Up to 150 words).
Existing partnerships will be continued with the Friends of Santa Ana NWR, community volunteers, and school groups.


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).
This progress report covers the period from May 2010 through October 30, 2010. 11 new occurences of invasive trees were found and treated in areas thought to be erradicated of invasive trees. Maps were produced of invasive tree treatment. Invasive grasses have been erradicated around Visitor's Center and in Visitor's Center parking lots. Work will continue through March 2011 on both invasive grass control (chemical and mechanical removal) and invasive tree control by both volunteer intern and other community volunteers.
Number of Acres Treated: 115
Number of Acres Inventoried and/or Mapped: 10
Number of Acres Restored: 15

Recommendations: (OPTIONAL)
How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program was a critical component of the control of invasive species on the refuge. These funds were used for enhancement of habitat and also enhancement of visitor use areas on the refuge.
