Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
Volunteers helped inventory islands for rats and they entered data into the database at Island Conservation. Other volunteers dissiminated information about the rat issue and findings at the Refuge visitor center and in displays and poster at various public venues.
Total Number of Volunteers: 6 Island Conservation, 8 Refuge and other FWS
Total Number of Volunteer Hours: 400
List both new and existing partnerships utilized in this project. (Up to 150 words).
The primary refuge partner was Island Conservation, a non-profit science driven organization, located at the University of California, Santa Cruz. This organization maintains expertise in on invasive species and they maintain an invasive species database for North America.


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).
Field studies were conducted in August and September 2006 in the central Aleutian Islands. These including visiting 13 islands to determine presence or absence of Norway Rats. The information was used to design a study of rodenticide efficicy in September 2006, to determine the minimum distance from source islands satellite islands needed to be to avoid invasion by rats, and the basic inventory data became part of a broader invasive database maintained by Island Conservation.
Number of Acres Treated:
Number of Acres Inventoried and/or Mapped: 1000+ (more importantly 13 islands)
Number of Acres Restored:


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 was essential in designing a critical study that is a pre-requisite for rodent eradication on a management scale. It also added to the basic inventory of target islands with rodents.
