     European water chestnut was found in the Rideau River last summer, with attempts at mechanical removal being quickly made by local officials. However, those same officials suspect that some seeds may have survived.

     "They remain viable for several years, said Chelsey Ellis, "so we can get the plants that come up this year, but will need to return in future years." 

     The detrimental invasive is known for out-competing its native counterparts, creating dense mats that often shade out vegetation underneath and posing a hazard to pets and recreational swimmers. 

     Events will be hosted throughout the summer for volunteers to help combat this and other invasive species; details available through the original article below.
