Road warriors, stealthy plants and stressed trees: Indulge your curiosity with NotMISpecies webinars

Did you know that road rights-of-way can be hot spots of invasive species infestation? Were you aware that that some retailers in Michigan will take back aquarium pets if you have too many? Have you heard about lesser celandine, Michigan’s newest watch list plant? Have you thought about the impacts of climate change on Michigan’s forests?

If you are curious about these or other invasive species issues, check out the NotMISpecies webinar series.

Supported by the Michigan Invasive Species program, the monthly, hourlong webinars are designed to keep people informed about available programs, current research and emerging issues in the state and the Great Lakes region. Question and answer sessions and links to resources help attendees get the most out of each presentation.

Pesky pets and plants

What can be done when non-native aquatic plants and pets outgrow or overpopulate their aquariums or water gardens? In “Don’t Let it Loose! Protecting Michigan’s Waterways from Pesky Pets and Plants” [ [link removed] ] (9 a.m. Tuesday, Jan. 14), Paige Filice shares how the “don’t let it loose” message is being promoted through surrender events and partnerships with leading retailers and conservation organizations. Filice is a natural resources educator and associate director of the Michigan State University Extension Center for Lakes and Streams. Since 2015, MSUE has been empowering aquarium and water garden retailers and enthusiasts to make sound stocking decisions through the Reduce Invasive Pet and Plant Escapes, or RIPPLE, campaign.



Road trippin’

Whether you’re hitting the highway for work or pleasure, you may not notice the condition of road rights-of-way unless you end up on the roadside with car trouble. Fortunately, the folks at the Michigan Department of Transportation pay attention to every one of the nearly 10,000 miles of state highway. Join MDOT’s Carla Ahlschwede for “Road Trippin’: How MDOT Manages Michigan’s Highways” [ [link removed] ] (9 a.m. Tuesday, Feb. 25), as she shares how the department keeps our highways safe and the role it plays in managing invasive species along roadsides across the state.

Disappearing act

In 2024, lesser celandine (Ficaria verna), a spring ephemeral plant found in forest floodplains, was added to Michigan’s watch list. The plant appears very early in spring and hides underground well before summer’s heat begins. In “Now You See Me, Now You Don’t! The Trick of Finding and Managing Invasive Lesser Celandine” [ [link removed] ] (9 a.m. Thursday, March 27), Katie Grzesiak, terrestrial invasive species coordinator with the Department of Natural Resources, explains the impacts, identification and management strategies for this invasive plant. Learn how to become a spring lesser celandine spotter on your next outdoor adventure.



Trees at risk

Invasive insects and diseases, including hemlock woolly adelgid, beech bark disease and beech leaf disease, are taking a toll on Michigan’s forests. As if this weren’t enough, the changing climate is further stressing trees and may lead to greater impacts by both invasive and native insects and diseases. Join forest entomologist Erin Biggs and forest pathologist Simeon Wright of the DNR for “They’ll Need that Hug: How Climate Change is Increasing Native and Invasive Threats to Michigan’s Trees” [ [link removed] ] (9 a.m. Wednesday, April 30). The duo will explain emerging issues, how they are being addressed, and which may have the biggest effect on Michigan’s forests and urban landscapes.

Recorded versions of all previous webinars are available on the NotMISpecies webpage. [ [link removed] ]
