The non-native version of common reed (Phragmites australis) was introduced to North America from Eurasia in the late 1700s to early 1800s. It is an aggressive, tall, dense wetland grass that crowds out native vegetation. In Utah it has colonized vast acreages around the Great Salt Lake and other wetlands resulting in a loss of habitat for wildlife and access by people. It is also found in smaller wetland areas at the urban/rural interface. Controlling small, urban populations is important to reducing the spread of this weed.
