Aquatic Invasive Species in Michigan: Recap | Rebecca Renirie and Anne Heidemann

On February 18, 2021, the University Libraries and the Saginaw Chippewa Tribal Libraries co-sponsored the event, Aquatic Invasive Species in Michigan, in partnership with the Clarke Historical Library. The two speakers, Anna Monfils and Chase Stevens, spoke about their experiences working with aquatic invasive species with a focus on European frogbit (EFB). This plant can form thick mats that choke out native species and negatively impact local recreational activities.

Dr. Monfils, a professor of biology and Director of the CMU Herbarium, opened the event with an overview of how the invasive escaped from a botanic garden in Canada and into the waterways of the Great Lakes, and then to inland waters in the state of Michigan and beyond. She then outlined the work she, her students, and the team from EFB Collaborative have done to study the distribution, lifecycle, and phenology of this plant. She shared that EFB can reproduce vegetatively through stolon buds and turions, which can remain dormant for a time until sprouting again.

Chase Stevens, Invasive Species Coordinator for the Saginaw Chippewa Indian Tribe of Michigan, spoke about his work with aquatic invasive species including EFB. Chase documented the different methods the Saginaw Chippewa Tribe has used to remove EFB chemically and manually. During one community event, where volunteers went out in boats and hip waders, they removed more than 500 pounds of the plant. Over the past few years, the Tribe and partners from the local Cooperative Invasive Species Management Area (CISMA) have removed about 5,000 pounds, or over two tons, of European frogbit from the Saginaw Bay.

In honor of both speakers, CMU Libraries’ biology librarian, Rebecca Renirie, and Saginaw Chippewa Tribal Education Librarian, Anne Heidemann, selected ten books, five for each speaker, to add to the collections of both libraries. Each book contains a bookplate recognizing the speakers’ backgrounds and professional work. The books are written for a range of audiences.
