Phragmites australis subspecies australis is a non-native species that forms dense monocultures and negatively affects wetland ecosystems. In this study, Geographic Information System (GIS) was used to analyze and compare intrinsic rates of growth between Phragmites populations located along highways and those within parks in Summit County, Ohio. No significant difference in expansion rate was seen between the two population types during a 4-year time period, although the average expansion rate was higher in park populations. Obstruction by roads may have prevented highway populations from expanding radially, while 2/3 of park populations were unobstructed in terms of physical barriers to expansion.
