For the first time, an invasive aquatic plant called water soldier has been discovered in Lake Simcoe, and it could impact local residents who enjoy fishing, boating, and swimming in the lake.
Water soldier is a tough, spiky plant that can grow in dense mats, crowding out native plants and potentially altering the water’s chemistry.
It was once used in water gardens before being banned under Ontario’s Invasive Species Act.
Now, it poses a threat to the lake’s delicate ecosystem and your summer fun.
The Water Soldier Working Group, made up of various provincial ministries, conservation authorities, and environmental organizations, has sprung into action to manage the spread.
They’re actively surveying the lake and developing treatment options.
Experts from the Lake Simcoe Region Conservation Authority warn that if left unchecked, water soldier could significantly alter the lake’s habitats, especially for fish species.
