How to tell the native Phragmites from the Invasive Introduced Form
Over at the Blog " Through Handlens and Binoculars " Scott Namestnik has a good post about how to separate the native form of Common Reed Phragmites australis ssp americanus from the invasive European P. a. ssp australis. There is also a link to an excellent power point presentation of " A Phragmites Field Guide : Distinguishing Native and Exotic Forms of Common Reed (Phragmites australis) in the United States". by Jil Swearingen and Kristin Saltonstall. _____ updated Sept. 28th to fix the links.
