Project Title: Inventory & Mapping of Native & Invasive Plant Species
Region: 2
Station: Texas Mid-Coast NWR Complex

Project Description:
(Up to 250 words)
As part of our CCP process, vegetation studies and ground data collection will be accomplished across the Complex through the assistance of SCAs. Using Trimble units, ArcPad, and ArcGIS, the SCAs will identify current vegetation alliances and any invasive species that are present in each polygon. Each polygon, generated by a computer program, must be ground-truthed, and the vegetation alliance recorded.
List of Invasives Species Targeted:Common NameScientific Name
  Baccharis Baccharis halimifolia

Describe the type of work the volunteers performed. (Up to 150 words)
SCAs were responsible for using Trimbles, Arcpad, and ArcGIS to map current locations and extent of populations of several identified invasive species. SCAs mapped locations and the percentage of area covered by invasive species within identified polygons. SCAs also participated in Chinese tallow eradication project and reading fire monitor plots, which shows information on the current status of invasives and their response to wildland and prescribed fire.
Total Number of Volunteers: 2

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).
Approximately 1/3 of the 1,906 polygons were completed. The vegetation alliance and non-associated vegetation have been identified as well as the existence of any invasives, native, or non-native for each polygon. Those areas were mapped and can be used for future assessment of habitat quality. It was identified that Baccharis has been reduced in areas of high disturbance due to drought, and that tallow is making a presence in areas that weren't identified earlier. This work occurred at San Bernard NWR and was a regional office project that met RLGIS compliance. All San Bernard fire monitor plots were completed, and all but 3 at Brazoria NWR and 2 at Big Boggy NWR were also completed.
Number of Acres Treated: 4
Number of Acres Inventoried and/or Mapped: 12,000
Number of Acres Restored: 0


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
There is so much field work that needs to be done and never enough people to do it. The SCA program is a very effective tool to assist in accomplishing field work, while giving students the opportunity to gain valuable field experience.
