On Thursday, November 15th, the Mississippi Valley Field Naturalists 2018-19 series “Earth, Water, Wind and Fire” continues with a presentation by wildlife biologist Ken Allison, local Lanark County resident and former President of MVFN and the Ottawa Field Naturalists’ Club.
When Ken spoke about roadside and aquatic invasive plants in his “Green Aliens in Lanark County” presentation in 2012, invasive Phragmites, did not seem to be on this invasive plant expert’s radar.
However, during his upcoming presentation, Ken will focus on this plant, (Phragmites australis subspecies australis), one of the worst aquatic invasive plant species there is. He will explore the features of a healthy wetland, before leading us into the unhealthy realm of a wetland invaded by these disruptive plants!
Learn from Ken how to identify this plant and distinguish it from native Phragmites (Phragmites australis subspecies americanus) and other invasive plants, and how to deal with them on your property.
Ontario Phragmites Working Group: “When attempting to manage and control invasive Phragmites, it is important to first determine if the plants you are managing are the native or invasive strain of Phragmites. Native Phragmites is an important component of a healthy wetland ecosystem. It grows in marshes and unlike the invasive strain, does not typically develop into dense monocultures or degrade habitat quality.”
The Mississippi Valley Field Naturalists and other groups are helping to map the distribution of this invasive species in Ontario. For more information visit https://www.eddmaps.org/ontario/
