Project Title: Oregon Coast Invasive Species Mapping, Monitoring and Eradication program
Region: 1
Station: Siletz Bay National Wildlife Refuge
Contact Person:
Name and Phone Number
Jim Johnson, Facilities Operations Specialist
Project Description:
(Up to 250 words)
The primary ecological goal for Siletz Bay refuge is to allow natural tidal processes to guide estuary function with little human influence. This holds true for the marshlands but is more difficult to achieve in the surrounding uplands and forestlands due to the presence of invasive species. In these areas hands-on weed control is imperative to prevent the further spread of invasive species and subsequent degradation of the forest. This project used volunteers to detect, identify, map, treat and monitor invasive plants species on all uplands within Siletz Bay National Wildlife Refuge.

Refuge volunteers assisted in the treatment, monitoring and mapping of invasive species on Siletz Bay NWR.
Total Number of Volunteers: 2
Total Number of Volunteer Hours: 480
List both new and existing partnerships utilized in this project. (Up to 150 words).


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).
Volunteers used hand-held GPS units to collect data on infested areas; GIS was then used to maintain an invasive species database and create maps as needed. Mapping was used to monitor the progress of treatment and predict the vulnerability of areas not currently affected by invasive species. This will assist refuge staff and volunteers in prioritizing future treatments. Removal of invasives species by refuge volunteers is continueing on Siletz Bay NWR. This year 10 acres of refuge lands have been cleared of invasive species and over 210 acres have been mapped by volunteers.
Number of Acres Treated: 10
Number of Acres Inventoried and/or Mapped: 210
Number of Acres Restored:


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