Event description


In this free webinar, you will be able to join MNPhrag researchers for a presentation and Q&A session on invasive Phragmites response strategies for Minnesota!

Invasive Phragmites (Phragmites australis subsp. australis) is a non-native wetland grass that can degrade fish and wildlife habitat, native plant diversity, and impede access to lakes and riverways. Over the past two years, researchers at the University of Minnesota have been investigating the distribution of invasive Phragmites in the state. The MNPhrag project has documented 389 populations statewide through targeted staff surveillance and reports by community members and agency staff. Invasive Phragmites is most common in the Twin Cities metropolitan area, Chisago and Wright counties, and around the city of Duluth, and most populations appear to be of manageable size. These findings suggest there is a window of opportunity to reverse invasive Phragmites spread in Minnesota by mobilizing a strategic, coordinated response across the landscape.

MNPhrag researchers recently developed an assessment of capacity and possible strategies to support such an effort. Visit for more information about the MNPhrag project and invasive Phragmites in Minnesota. The assessment will also be available here after May 15th. We look forward to hearing your questions and comments during the discussion! The webinar will be recorded and available for later viewing.

Presenter and panel bios:

Dan Larkin is an Assistant Professor and Extension Specialist in the Department of Fisheries, Wildlife, and Conservation Biology and the Minnesota Aquatic Invasive Species Research Center at the University of Minnesota. His research addresses applied problems in ecological restoration and invasive species management in wetland, lake, and terrestrial plant communities. Through his Extension programs, Dan trains citizen scientists to increase Minnesota’s capacity for invasive species surveillance and response.

Julia Bohnen is involved in both research and teaching at the University of Minnesota related to ecological restoration and invasive species management. Her current research seeks to engage professionals and volunteers throughout Minnesota in identifying and reporting locations of invasive Phragmites to understand its likelihood to spread and its potential to impair ecological functions.

Chelsey Blanke is a researcher at the University of Minnesota working with the MNPhrag team to develop an assessment of capacity and statewide strategies for responding to invasive Phragmites in Minnesota. She is broadly interested in work that supports collaboration and solutions for the benefit both people and the environment.
