The dike trails will be closed Wednesday, September 10th for an aerial herbicide application to control stands of Phragmites australis, common reed, in the impoundment complex. The aerial application is weather-dependent - please call on Wednesday if you plan to use the East Dike Trail.


Phragmites australis is an invasive reed that takes over wetland areas. This tall plant outcompetes native vegetation and does not provide food for native wildlife. Herbicide application is one way to control the rapid spread of the plant or help remove the plant from areas it has invaded. Following herbicide application a prescribed fire can clear away the dead plant material so native seeds can grow without having to compete with the Phragmites.
