Eel-leaf watermilfoil (Myriophyllum épipterum) is an aquatic plant that has been observed in some Quebec waters. But what exactly is it, and how can you identify it?
La myriophylEel-leaf watermilfoil is a type of submerged aquatic macrophyte that can grow to considerable lengths, up to several meters. Its leaves are green and flat, with a characteristic "epis" shape.le à épis est un type de macrophyte (plante aquatique) qui pousse sous l'eau. Elle peut atteindre des longueurs considérables, allant jusqu'à plusieurs mètres. Ses feuilles sont vertes et plates, avec une forme caractéristique en « épis ».
But is eel-leaf watermilfoil really an invasive species? Some scientists suggest not. A study conducted by the Université Laval (1) showed that this plant plays an important role in aquatic ecosystems.
However, it's possible that excessive growth of eel-leaf watermilfoil can contribute to water quality problems. To identify this plant, look for its flat green leaves and "epis" shape.
Here are some key characteristics to help you recognize it:
- Leaf length: up to 10 cm
- Leaf shape: flat, with an "epis" form
- Color: green
- Habitat: submerged in shallow water
It's worth noting that other aquatic plants, such as pickerelweed (Sagittaria latifolia) or water lilies (Nymphaea spp.), can resemble eel-leaf watermilfoil. However, these plants are generally smaller and have different leaf shapes.
In conclusion, eel-leaf watermilfoil is an aquatic plant that can be identified by its unique characteristics. It's essential to monitor its growth to avoid any water quality problems.
