Studies have been done on the control mechanism of Phragmites. Crowe, Leclerc, Struger, & Brown (2011) did a study on glyphosate-based herbicide application on Phragmites near Georgian Bay beaches. The application of herbicides is not suggested near bodies of water, but this study used herbicide concentration below the Canadian water quality guideline for the protection of aquatic species (Crowe, Leclerc, Struger, & Brown, 2011). This study reduced the size of Phragmites by 90%, although it did not eradicate the invasive species, the reduction in size is a good control measure (Crowe et al., 2011). The herbicides used in this study, Roundup® or Rodeo®, do have toxic effect to aquatic life which is why the herbicides were diluted in the study (Crowe et al., 2011). Risk assessments should be done before the use of the herbicides since they do pose serious consequences and this is why herbicides are not often used as an eradication technique for Phragmites even though they are proven to be effective. Other control measures should be taken to prevent proliferation of this invasive plant. A provincial action plan must be created since Phragmites have been proven to affect native aquatic species. At Long Point, Ontario, the invasive plant has reduced habitats for 6 freshwater turtles nesting sites (Bolton & Brooks, 2010). The turtles require solar heat and open habitats with specific characteristics for nesting (Bolton & Brooks, 2010). The microenvironment that is suitable for…
