Phragmites, also known as the common reed, might seem like just another tall, swaying grass in the wetlands, but this invasive variety is a significant threat to our ecosystems. Let's explore why this plant is causing such a stir and what we can do about it.

What is Phragmites Australis?
Phragmites is a perennial wetland grass that can grow up to 15 feet tall. While there's a native variety, the invasive, non-native variety is becoming more widespread. These invasive Phragmites form dense stands that crowd out native plants and animals, block shoreline views, and can even create fire hazards with their dry plant material.
Why is it a Problem?
Invasive Phragmites degrades wetlands and coastal areas by taking over the habitat that native species rely on. They make it difficult for us to access these areas for activities like swimming, fishing, and hunting. Additionally, dense Phragmites stands can be an eyesore and a safety hazard for drivers.
How Can We Control It?
Managing invasive Phragmites requires a combination of methods:
Herbicide Treatment: An initial application of herbicide is essential for effective control.
Mechanical Removal: Following herbicide treatment, mechanical methods like cutting and mowing help to remove dead plant material and promote the growth of native species.
Prescribed Burning: For large areas, burning the treated plants can provide additional control and ecological benefits.
Early Detection and Ongoing Maintenance
Catching the invasion early is crucial. Early detection makes it easier and more cost-effective to manage Phragmites before they form large, dense stands. Regular monitoring and maintenance are key to preventing re-infestation.
Getting Involved
There are tools and resources available to help with managing Phragmites:
Great Lakes Phragmites Collaborative (GLPC): This regional partnership helps improve communication and collaboration for Phragmites management across the Great Lakes basin.
Phragmites Prioritization Tool: Developed by EGLE, this tool helps prioritize treatment and management efforts.
If you have invasive Phragmites on your property, make sure to follow the guidelines for proper identification, treatment, and removal. Avoid planting Phragmites, and if necessary, apply for the appropriate permits for chemical treatments.
By working together and staying vigilant, we can help protect our wetlands and coastal areas from the threat of invasive Phragmites.
