Learn about the various types of invasive weeds in your waterfront.
Brazilian Elodea:
It can be found in a wide range of freshwater habitats, including wetlands, lakes, ponds, and even slow-flowing streams.
While it is usually rooted at depths of 1-2m, it can be found in up to 6m of water, and can also drift freely.
Curly Pond Weed:
Wavy, curly leaves with serrated edges.
Often reddish-brown in color and grows in dense clusters.
Fanwort:
In Ontario, Fanwort was first found in Kasshabog Lake, part of the Crowe River watershed northeast of the City of Peterborough.
Since its discovery in 1991 it has spread year over year ever since.
Hydrilla:
This weed was introduced to North America in the early 1950s when it was brought to the southern United States for use as an aquarium plant.
It then spread into waterways when people emptied their aquariums into lakes or rivers.
Parrot Feather:
This weed is limited to non-tidal waters, including lakes, ponds, and slow-moving streams.
The populations found in North America are female plants, and as a result, can only reproduce vegetatively.
Starry Stonewort:
In Ontario, Starry Stonewort has been recorded all along the Trent-Severn Waterway, from Lake Ontario to Georgian Bay/Lake Huron, and several non-connected lakes and stormwater basins.
Water Chestnut:
European water chestnut (or water chestnut) is an invasive aquatic plant that has been introduced to the Ottawa River in eastern Ontario within Voyageur Provincial Park.
Watermilfoil:
Long, feathery leaves resembling a Christmas tree. Can form dense mats under the water's surface.
