Disturbance-Mediated Competition And The Spread Of Phragmites Australis In A Coastal Marsh, Todd Minchinton, Mark D. Bertness
Faculty of Science, Medicine and Health - Papers: part A
In recent decades the grass Phragmites australis has been aggressively invading coastal, tidal marshes of North America, and in many areas it is now considered a nuisance species. While P. australis has historically been restricted to the relatively benign upper border of brackish and salt marshes, it has been expanding seaward into more physiologically stressful regions. Here we test a leading hypothesis that the spread of P. australis is due to anthropogenic modification of coastal marshes. We did a field experiment along natural borders between stands of P. australis and the other dominant grasses and rushes (i.e., matrix vegetation) in …
