PHRAGMITES QUICK FACTS: • Phragmites is an erect, aquatic or riparian, perennial grass native to Eurasia that was introduced to North America for erosion control and as an ornamental plant. Native vs. Non-native. Taxonomy. Phragmites. Native Phragmites stands have been found in a few New England marshes. Potential: In controlled experiments, the introduced and native lineages of Phragmites australis were found to hybridize, which has the potential to act as a mechanism for further decline of native Phragmites in North America where it comes in contact with introduced stands (Meyerson et al. Invasive vs. The common reed typically forms denser stands than the native. Invasive Phragmites (European strain) is a tall, aggressively growing grass that can take over large areas of wetland and shoreline, push out native vegetation, and reduce habitat quality for wildlife. See you on The Bay, Heather Sargeant. Colonies of the invasive subspecies of common reed (Phragmites australis (Cav.) The GBNERR Coastal Training Program Johnston, and D.L. Fact Sheets and Identification Links. Stands that have been around for long periods are intermingled with other native plants. Habitat. Near-monotypic stands of this aggressive grass have replaced high quality, complex communities of native plants over thousands of acres of Michigan wetlands and coastal areas. Native phragmites typically occurs in low density stands often co-mingled with other native plants but it can occur in very dense stands. Coralberry( Symphoricarposorbiculatus )hassimilaropposite,entire The plant ranges in height from 6-13 feet. Species information. Common reed replaces native grasses, sedges, and herbaceous plants. Cryptic invasion by a non- native genotype of the common reed, Phragmites australis, into North America. Native Phragmites exists in Nebraska; native have loosely attached leaf sheaths while the non-native species has tightly adhered leaf sheaths. Non-native forms of Phragmitesare vigorous growing plants that once introduced can establish and take over a wetland, becoming a monoculture within several years. Phragmites is also known as common reed, giant reed, or canegrass. View the herbarium specimen image of the University of Florida Herbarium Digital Imaging Projects. mnfi.anr.msu.edu.

Similar species: Native Phragmites (Phragmites australis ssp. Trin. Phragmites / Common Reed. There are no recommended biological control methods at this time. This is complicated by the fact that there is a "native" phragmites and an "invasive or non-native" species. Today, invasive Phragmites can be found across North America and dominates along the Atlantic coast where few native Phragmites populations remain. Similar non-native species: No other non-native grass is so tall.Escaped Miscanthus ornamental grasses are showy but do not normally occur in wetlands..

Scientific name: Phragmites australis. Great Lakes Impacts: Phragmites australis has a high environmental impact in the Great Lakes. Introduced phragmites typically forms very dense stands of both live stems and standing dead stems from the previous year’s growth. The Plants Database includes the following 2 species of Phragmites . Mowing is one method to manage non-native phragmites, but it should be done several times during the growing season to be effective. Non-native Phragmites can alter habitats by changing marsh hydrology; decreasing salinity in brackish wetlands; changes … It provides poor quality habitat for insects, birds and amphibians. Phragmites australis (frag-MY-teez), also known as common reed, is a perennial, wetland grass that can grow to 15 feet in height.While Phragmites australis is native to Michigan, an invasive, non-native, variety of phragmites is becoming widespread and is threatening the ecological health of wetlands and the Great Lakes coastal shoreline. Another less common native honeysuckle species, Swamp Fly- honeysuckle( L.oblongifolia )hasyellowflowersintheleafaxils. is native to Alberta, complicating identification from invasive . americanus (native). Mowing alone will not provide control. … It is in the family Poaceae (Grass family). Maine Cooperative Extension Fact Sheet for Common Reed (Phragmites) Tip of the Mitt Watershed Council, Minnesota, Identification Video (5:50) Scientific Name Neyraudia reynaudiana Phragmites australis Specimen Common Reed (Phragmites australis) can rapidly form dense stands of stems which crowd out or shade native vegetation in inland and estuary wetland areas.Phragmites turns rich habitats into monocultures devoid of the diversity needed to support a thriving ecosystem. Sources used in this post include: “Phragmites: Native or Not”. Native Phragmites do occur in the United States and they are sometimes very difficult to distinguish from the exotics. 2007.
