Subject: New Resources: How to Search for Zebra Mussels


Hello AIS Partners,


In our work with you, we have heard requests for better guidance on how to search for zebra mussels. DNR staff worked to create these resources to meet your needs. It is a simple guidance document for citizens that are interested in searching for zebra mussels on their lake or river and a tracking spreadsheet and report card for local government staff coordinating these volunteer efforts. The attachments are as follows:


1.                   How to Search for Zebra Mussels – details search and reporting methods.

2.                   Zebra Mussel Absence Report Spreadsheet – a way to track search efforts. This could be sent to each volunteer if they prefer to record their data electronically. Coordinators can compile volunteer data each year into this spreadsheet and share it with the DNR.

3.                   Zebra Mussel Absence Report Postcard – a reminder card for volunteers to perform and record their search efforts. Volunteers can send this “report card” to you at the end of the season.


If you have any questions about these documents, please let us know.


Finally, please let us know if you test out these resources this season. Let us know what worked well, what challenges you encountered, and what improvements could be made. We want this to be as useful as possible for those of you implementing these types of initiatives on the ground. We will gather feedback and update the resources as needed for next season.


As always, thank you for all the work that you do!


Your Friendly AIS Prevention Planners
