Hybrid Happenings: The Latest on Hybrid Watermilfoil in Minnesota
Join the Minnesota AIS Detectors program on May 22, 2020 at 1:00 pm CDT for the next in our Aquatic Invasive Species Webinar Series!
About this webinar: Hybrid watermilfoil, formed from the hybridization of the native northern watermilfoil (Myriophyllum sibiricum) and the invasive Eurasian watermilfoil (M. spicatum), has been present in Minnesota for over 20 years. Surveys in 2017 and 2018 documented hybrid watermilfoil in 28 of 62 lakes surveyed. Eurasian was found in 43 lakes. Most Eurasian populations were the same clone and only 6 genotypes were found, but hybrid watermilfoil was much more diverse; 51 genotypes of hybrid watermilfoil were noted.
The concern with hybrid watermilfoil is that some genotypes may be more invasive or resistant to commonly used herbicide. This webinar will provide updated results from 2019, including results from additional lakes and response to management activities in a set of intensively studied lakes. The webinar will also provide a background for a set of virtual meetings the following week to discuss our sampling and survey plans for 2020, observations from stakeholders and opportunities for collaboration and interest in developing a genetic database to aid management and containment.
