Alien Species

1. Butomus umbellatus (aquatic plant)

Butomus umbellatus commonly known as flowering rush, is a moderately tall, rush like perennial found on shores of lakes, ponds and riverbanks. It can tolerate water as deep or deeper than 2 metres, extending to the deepest range of emergent marsh species. Flowering rush can displace native riparian vegetation, and can be an obstacle to boat traffic. Once established, populations' increase and can persist indefinitely. Control of this species is very difficult, especially with herbicides because they easily wash away from the narrow leaves of this plant. Extensive physical methods of control must be employed to manage this invasive exotic. It can be spread over long distances by garden planting, and once established in a watershed it spreads locally by rhizomes and root pieces that break off. Muskrats use parts of the plant and contribute to its local spread. Boaters can also transport flowering rush on their equipment.

Common Names: butome à ombelle, flowering rush, flûteau, grassy rush, jonc fleuri, water gladiolus

2. Hydrocharis morsus-ranae (aquatic plant)

Hydrocharis morsus-ranae is a free-floating herbaceous annual aquatic that can reach 20cm in length. It does well in calm open waters, and can be found in marshes, ditches and swamps. H. morsus-ranae produces dense floating mat of vegetation which restrict available light, dissolved gases, and nutrients. This species displaces native flora and is perhaps impacting the fauna. There is currently no management information available but there is currently a study that started in 2003 and will go through 2005 that is looking into and researching methods of controlling H. morsus-ranae on the Great Lakes and St. Lawrence River.

Common Names: common frogbit , European frog's-bit

3. Lythrum salicaria (aquatic plant, herb)    

Lythrum salicaria is an erect perennial herb with a woody stem and whirled leaves. It has the ability to reproduce prolifically by both seed dispersal and vegetative propagation. Any sunny or partly shaded wetland is vulnerable to L. salicaria invasion, but disturbed areas with exposed soil accelerate the process by providing ideal conditions for seed germination.

Common Names: Blutweiderich, purple loosestrife, rainbow weed, salicaire, spiked loosestrife

Synonyms: Lythrum salicaria var. gracilior Turcz., Lythrum salicaria var. tomentosum (P. Mill.) DC., Lythrum salicaria var. vulgare DC.

4. Myriophyllum spicatum (aquatic plant)

Myriophyllum spicatum is a submerged aquatic plant that can rapidly colonise a pond, lake or area of slow-moving water. It creates dense mats of vegetation that shade out other native aquatic plants, diminish habitat and food resource value for fish and birds, and decreases oxygen levels in the water when the plant decays.

Common Names: Eurasian water-milfoil, spike water-milfoil

Synonyms: Myriophyllum spicatum L. var. muricatum Maxim.

5. Potamogeton crispus (aquatic plant)

Potamogeton crispus is an aquatic plant that grows in fresh and slightly brackish waters. It becomes invasive in some areas because of its tolerance to low light and low water temperatures. These tolerances allow it to outcompete native plants in the spring. Using this life cycle, P. crispus can be controlled best in spring or early summer when native species are still dormant and temperatures are low enough for endothal herbicides to be effective.

Common Names: curly pondweed, curly-leaved pondweed

Native Species

1. Cabomba caroliniana (aquatic plant)

Cabomba caroliniana is a submerged perennial aquarium plant that grows in stagnant to slow flowing freshwater. It spreads primarily by stem fragments and forms dense stands that crowd out well-established plants. C. caroliniana may clog ecologically, recreationally or economically important water bodies and drainage canals. Depending on its location (ie: drinking water supply or small closed water body) it may be managed by a number of control techniques including mechanical removal (being careful not to spread fragments to new locations) and habitat modification to increase shading (via planting trees) or decrease hydration (via draining).

Common Names: cabomba, Carolina fanwort, Carolina water-shield, fanwort, fish-grass, Washington-grass, Washington-plant

2. Ceratophyllum demersum (aquatic plant)

Ceratophyllum demersum is a native of North America. It now has a worldwide distribution, at least in part due to the aquarium and pond trade. It is a submerged aquatic plant which is capable of forming dense monospecific beds, excluding other plant species, causing problems to recreational activities on waterways and in some cases causing blockages at hydroelectric power stations. C. demersum can spread rapidly, and grows in a large range of aquatic habitats.

Common Names: common hornwort, coon's tail, coon's-tail, coontail, hornwort, rigid hornwort

Synonyms: Ceratophyllum apiculatum Cham., Ceratophyllum demersum var. apiculatum (Cham.) Aschers., Ceratophyllum demersum var. apiculatum (Cham.) Garcke

3. Nymphaea odorata (aquatic plant)

Nymphaea odorata is an aquatic plant with floating leaves that can thrive in a variety of aquatic habitats and tolerates variable environmental conditions. It forms dense floating mats of vegetation that prevent light from penetrating through the surface. Distributions of phytoplankton, zooplankton, aquatic insects and fish populations are altered. Nymphaea odorata can also restrict waterfront access and eliminate swimming opportunities.

Common Names: American waterlily, American white waterlily, fragrant waterlily, white waterlily
