Claire Peterson Posted November 14, 2017 Report Share Posted November 14, 2017 Hi everyone! We received a message through our Facebook page from a concerned citizen about the aquatic plant shown. She wants to know what this could be and if it is invasive. The location is Sugden Lake in Oakland County Quote Link to comment Share on other sites More sharing options...
Anna Weis Posted December 11, 2017 Report Share Posted December 11, 2017 Really hard to tell from the picture - it could be several things. A good close up picture of the number of leaves whorled around the stem would be super helpful, & we might be able to make a positive ID here. Here's a link to a helpful little book called "A Field Guide to Invasive Plants of Aquatic and Wetland Habitats for Michigan". They can read the book on-line, and it has good descriptions. http://mnfi.anr.msu.edu/invasive-species/AquaticsFieldGuide.pdf Another helpful link below...goes to state of Michigan website with invasive species profiles. http://www.michigan.gov/invasives/0,5664,7-324-68002---,00.html Unfortunately, the natives look very similar to the invasive species, so they really should collect a sample for positive ID. ~Anna Quote Link to comment Share on other sites More sharing options...
Claire Peterson Posted December 11, 2017 Author Report Share Posted December 11, 2017 Hi Anna! These were the two additional photographs that were sent to me. Phyllis was unable to identify it but she wanted me to pass along a milfoil power point that had been done. I've received no updates from the person who contacted us since sending that information.

Jo Latimore Posted March 19, 2018 Report Share Posted March 19, 2018 Definitely a milfoil, and most likely native from what I can see here. Actually being able to see a single leaf sure would help, but the leaflet spacing that I can make out, as well as the general "stiffness" of the plant lead me to think native (as opposed to the invasive Eurasian). (I realize this is way late but since no one else had replied...) Quote Link to comment Share on other sites More sharing options...
