Invasive Phragmites from Barbara Lucas on Vimeo.
Another great video produced by Barbara Lucas, this short film focuses on the non-native invasive Phragmites australis subsp. australis. Sometimes referred to as common or giant reed, many of us in "the biz" just call it Phragmites, pronounced frag-MY-tees. This plant is a wetland species, but will also grow on beaches and even wet, seeping hillsides- it doesn't need very much water. This is one plant that I've seen expand in my relatively short lifetime.
Also- There is a native phragmites that has been recently described and named Phragmites australis subsp. americanus. It too is mentioned in the video. Currently, this native grass is a state threatened species. I wrote and article detailing it in the 2007 Winter issue of Natural Ohio.
