Experiment

Seymour Lake is Broken (floating) Hearted

By Madeleine Guenette

My project is about how different cutting methods affect the regrowth of the floating heart weed on Seymour Lake. I am curious about this topic because I live on Seymour Lake and this invasive weed is taking over the lake. If I can determine the best cutting method to stop it, then the Seymour Lake Society and the managers of other lakes that are battling this weed, can use my results to save their lakes from floating heart. I set up seven test sites, in areas that have floating heart as well as other weeds. At each site, I did one of the following: continual selective plucking, root removal twice during the experiment, or nothing. My hypothesis was that continual selective plucking would be the best method and that the weed would have big outbreaks at the no cut sites. My experiment showed that root cut method is the best. The role that other plants play in stopping floating heart growth surprised me; there is a real war going on there. In order to be sure of my results, I need to continue this study for another year.
