Mid-Michigan CISMA is surveying for European Frog-bit this summer. Please keep an eye out for it at any water body you visit and let us know if you find it! Report it to www.misin.msu.edu with a photo and the GPS coordinates so we can find it again!

Happy everyone! Today's spotlighted species is European frog-bit, or Hydrocharis morsus-ranae. This is a perennial, free-floating aquatic herb that forms dense matts in shallow, slow moving water on the edges of lakes and rivers. Its primary form of reproduction is through turions, or winter buds that drop to the bottom during the fall and float to the top to form new plants in the spring. One plant can produce up to 100 turions a year, allowing the colonies to form rapidly. The concern associated with frog-bit is that the dense matts that it forms can inhibit boat traffic and drastically reduce local diversity. Check on the link below for more information as well as info on how to accurately identify European frog-bit. As always, have a great week!

Today the Michigan Commission of Agriculture and Rural Development voted to approve the regulation of six invasive plants.

Water lettuce (Pistia stratiotes) and water hyacinth (Eichornia crassipes) will be added to the state's prohibited list with regulations going into effect this summer.

Callery pear (Pyrus calleryana), Japanese barberry (Berberis thunbergii), common buckthorn (Rhamnus cathartica) and glossy buckthorn (Frangula alnus) will be added to the restricted list with regulations going into effect on January 1, 2028.

If a species is prohibited or restricted in Michigan, it is unlawful to possess, introduce, import, sell or offer that species for sale as a live organism, except under certain circumstances.
