Summary
Myriophyllum alterniflorum, also known as alternate water-milfoil or alternateflower watermilfoil, is a species of water-milfoil native to Europe and Asia. It has a circumboreal distribution and is found mainly in Canada and some northeastern states in North America. It is an aquatic macrophyte with stems that are submerged and have delicate branches and foliage, with leaves that are small (4-12 mm) and finely dissected and whorled on the stem. It is classified as an endangered species in Massachusetts and does not have a federal status. It is monoecious, rarely with bisexual flowers, and does not have perennating turions. It is found in soft water lakes with sandy, gravelly or mucky bottoms that are either clear or dark tannin-stained. It is listed in the USDA Plant Database.

Alternate Water Milfoil: Understanding the Invasive Plant Species
Alternate water milfoil, scientifically known as Myriophyllum alterniflorum, is an invasive plant species that is commonly found in freshwater bodies such as lakes, ponds, and rivers. This plant species is native to North America and is known for its fast-growing nature, making it a challenge for aquatic ecosystems. In this blog, we will discuss the features and impacts of alternate water milfoil on the environment.
Features of Alternate Water Milfoil:
- Leaves: The leaves of alternate water milfoil are feathery, with delicate leaflets that grow in a whorl pattern around the stem.
- Stem: The stem of alternate water milfoil is slender and flexible, with a red or reddish-brown color.
- Flowers: The flowers of alternate water milfoil are small and grow in clusters at the top of the plant. They are typically pink or white in color.
Impacts of Alternate Water Milfoil on the Environment:
- Overgrowth: Alternate water milfoil can grow very fast and can easily outcompete native aquatic plants, leading to a reduction in the diversity of aquatic plant species.
- Habitat destruction: The overgrowth of alternate water milfoil can lead to the destruction of habitats for aquatic animals and plants, which can result in declines in local populations.
- Water quality degradation: Alternate water milfoil can release chemicals into the water that can alter the water chemistry and reduce water quality. This can negatively impact aquatic life and make the water unsuitable for human use.
Management of Alternate Water Milfoil:
The management of alternate water milfoil requires a multi-pronged approach that includes a combination of mechanical, chemical, and biological methods.
-
Mechanical methods: Mechanical methods involve removing the plant from the waterbody manually or with specialized equipment. This method is effective in small waterbodies but can be labor-intensive and costly in larger waterbodies.
-
Chemical methods: Chemical methods involve the use of herbicides to control the growth of alternate water milfoil. This method is also effective but requires careful planning and execution to minimize the impact on the surrounding environment.
-
Biological methods: Biological methods involve introducing a natural predator, such as a type of weevil, to control the growth of alternate water milfoil. This method is considered more environmentally friendly than chemical methods but requires more time to be effective.
In conclusion, alternate water milfoil is a challenging invasive plant species that can have significant impacts on the environment. However, with proper management, it is possible to control the growth of this species and protect the health of aquatic ecosystems.
In addition to the management methods mentioned above, there are also preventative measures that can be taken to minimize the spread of alternate water milfoil. Some of these measures include:
-
Cleaning boats and equipment: Boats and fishing gear can easily spread plant fragments from one waterbody to another, so it is important to clean these items thoroughly before moving them between waterbodies.
-
Monitoring waterbodies: Regular monitoring of waterbodies can help detect the presence of alternate water milfoil early on, allowing for quicker and more effective management.
-
Education and outreach: Education and outreach efforts can help raise awareness about the impacts of invasive species and the importance of preventing their spread.
It is important to keep in mind that controlling alternate water milfoil is an ongoing process and requires continuous effort from local governments, community organizations, and individual citizens. By working together, we can help protect our aquatic ecosystems from the negative impacts of invasive species.
In conclusion, alternate water milfoil is a challenging invasive plant species that can have significant impacts on the environment. However, with proper management, preventative measures, and community efforts, it is possible to control the growth of this species and protect the health of aquatic ecosystems.
