Project Description:
(Up to 250 words)
Currently, Phragmites australis exists on the Refuge in several small (<5 ac.) patches. It is expanding its area coverage annually, but no quantitave survey of this species has been completed. In 2003 Iroquois NWR initiated a mapping project designed to document all patches of Phragmites on the Refuge. These data will result in a baseline map that will be used to document the change in Phragmites occurrence over time. Prior to 2005, approximately 65% of the Refuge had been surveyed. This grant would allow completion of the project and would result in 100% documentation of Phragmites on the Refuge. Additionally, several small patches of Phragmites will be sprayed with herbicide in 2005 in an effort to initiate a control program on the Refuge. These patches have already been mapped and monitoring will consist of post spray survey and mapping to determine the efficacy of control. Lastly, a small portion of this grant money will be used to initiate surveys of other invasive plants on the refuge as well as the continued monitoring of biological control of purple loosestrife which was initiated in the early 1990s.

Volunteer Involvement:
Describe the type of work the volunteers performed. (Up to 150 words)
A total of four refuge volunteers (1 intern, 2 volunteers and 1 Friends of INWR, Inc. member) assisted in this project. Volunteer involvement consisted of inventory and mapping, data entry and design and printing of an informational leaflet.
Total Number of Volunteers: 4
Total Number of Volunteer Hours: 393
List both new and existing partnerships utilized in this project. (Up to 150 words).
We used our partnership with the Friends of Iroquois NWR, Inc. to design and print an Invasive Species informational leaflet.


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).
As a result of this grant the refuge was able to complete the inventory of common reed on the entire refuge. An ArcView map layer showing the location of all common reed patches on the refuge has been completed. Additionally, we were able to begin the inventory of two other invasive species (multiflora rose and Japanese knotweed). We discovered that multiflora rose is more common than we had previously thought. We also discovered that there were no patches of Japanese knotweed in the refuge areas that were surveyed, but we did document a small patch of this plant immediately adjacent to the refuge on private land. This information will allow us to contact the landowner in an attempt to control this invasive species before it reaches the refuge. A biological control program for purple loosestrife was started several years ago on the refuge and adjacent state wildlife management areas. Qualitative monitoring of the success of this program has been ongoing and this year the funding received from this grant allowed us to continue this monitoring program. Herbicide purchased with the grant money was used to begin control efforts for common reed and black swallowwort. Common reed is present in many patches on the refuge and will likely take several years to control. Initial results from control efforts are encouraging as approximately 80% of the plants sprayed appear to have died. Black swallowwort is limited to one small patch and with early detection and control efforts, we should be able to eliminate this aggressive exotic from the refuge. Initail spray results appear to have had good success. We have developed an invasive species informational leaflet that we will offer to refuge visitors. Information such as history of invasive species, species specific problems and control efforts, and general precautions to limit the introduction and spread of invasive species are included.
