Physical Characteristics Phragmites australis is a PERENNIAL growing to 3.6 m (11ft) by 3 m (9ft) at a fast rate. Phragmites australis (Cav.) ... characteristics. Fourn.) P. australis is very common in both freshwater and brack-ish wetland habitats (Saltonstall 2003), and P. australis— 2015. 2007). ... and many traits associated with large genomes are not compatible with the characteristics of successful invaders (Suda et al., 2015). Saltonstall, K. and D. Hauber. AoB Plants: pls022. Chiov., Reimaria diffusa Spreng., Trichoon phragmites (L.) Rendle. Phragmites australis also had some traditional ethnobotanical uses for several Native American tribes (University of Michigan 2016). Antibiotic pollution has become a hot issue worldwide, which has toxic effects on plants and even threatens human health. 2010, Swearingen and Saltonstall 2010). Plants growing in harsh environments may not be able to flower, so the only mode of reproduction is vegetative (Haslam 1972). It has been found that both the native and the introduced lineages regularly sexually reproduce and establish via seed dispersal and have extensive flowering time overlap (Brisson et al. 413 pp. The leaves are long for a grass, 20–50 cm (7.9–19.7 in) and 2–3 cm (0.79–1.18 in) broad. 2014. Trin. Leaf-blade apex attenuates; filiform (Clayton et al. † Populations may not be currently present. [Accessed 7 September 2011]. [Accessed 23 May 2016]. Available http://www.mnr.gov.on.ca/stdprodconsume/groups/lr/@mnr/@sorr/documents/document/stdprod_086861.pdf. australis is causing serious problems for many other North American hydrophyte wetland plants, including the native Phragmites australis subsp. The pyrolytic kinetics of Phragmites australis was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. australis are fully effective used alone, and reinvasion is likely when the management strategy is not maintained. ex Steudel (Poaceae), or common reed, is a worldwide perennial grass found in every continent except Antarctica. ex Hicken, Phragmites fissifolius Steud., Phragmites hispanicus Nees, Phragmites isiacus (Delile) Kunth, Phragmites martinicensis Trin. Initial introduction to the United States was likely via solid ballast and/or packing material from shipping (Swearingen and Saltonstall 2010). Lemma are glabrous; lanceolate; 8–15 mm long; membranous; acuminate; with somewhat in-rolled margins. Leaf blade surface smooth; cauline (Clayton et al. Rhizomes of the native subspecies rarely exceed 15 mm in diameter and are a darker yellow than the introduced lineage (Swearingen and Saltonstall 2010). 2006). U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). Inflorescence a panicle; bearing juvenile spikelets at emergence (Clayton et al. 2006). Introduced Phragmites australis reproduces primarily clonally through the production and fragmentation of underground rhizomes, but is capable of sexual reproduction through seeds … 2012. Suitable … berlandieri (E. 2014). …common, or water, reed ( Phragmites australis) occurs along the margins of lakes, fens, … Nelson, L.A.M. Available http://www.nps.gov/plants/alien/pubs/index.html. Great Lakes Commission. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. [13], Since 2017, over 80% of the beds of Phragmites in the Pass a Loutre Wildlife Management Area have been damaged by the invasive roseau cane scale (Nipponaclerda biwakoensis), threatening wildlife habitat throughout the affected regions of the area. Care should be taken to clean all equipment used for mechanical removal prior to transportation from the treatment site (Great Lakes Phragmites Collaborative 2015). 2009. 2010, USFWS 2007). Data Source and Documentation: About our new maps. 2007. Phragmites is wind-pollinated; cross pollination with other plants is probably most common, but self-pollination or agamospermy may occur (Gucker 2008). If a population can be controlled soon after it has established chances of success are much higher because the below-ground rhizome network will not be as extensive. It was used as a forage plant; the seeds were eaten in the absence of other foods (University of Michigan 2016). Cross pollination of common reed flowers is probably most common, but self pollination or ... 0.5–0.6 length of upper glume; membranous; without keels; 3–5 veined. 2007. It is in flower from July to September, and the seeds ripen from August to October. Plant Signaling & Behavior 4(6): 506-513. [Accessed 23 May 2016]. The list of references for all nonindigenous occurrences of Phragmites australis australis are found here. Common reed is a large rhizomatous/stoloniferous cool season grass obtaining heights of up to 4 m (13 ft) with stems averaging 0.5 to 1.5 cm (0.2 to 0.6 in) in diameter. Introduced Phragmites is more likely to form monocultures, outcompeting and excluding other plant species. Hybridization of invasive Phragmites australis with a native subspecies in North America.

Distinguishing Between Native and Non-native Phragmites australis: Many morphological characteristics can be used to distinguish native Phragmites australis subsp. Carlton. Blossey, B., M.

Potential for Biological Control of Phragmites australis in North America. Its success may also be attributed to allelopathy, Phragmites releases gallic acid, which is degraded by ultraviolet light to produce mesoxalic acid, effectively hitting susceptible plants and seedlings with two harmful toxins (Rudrappa 2009). 2014). Phragmites australis management in the United States: 40 years of methods and outcomes. Tewksbury, L., R. Casagrande, B. Blossey, P. Hafliger, and M. Schwarzlander.

Spartina alterniflora and invasive Phragmites australis stands have similar greenhouse gas emissions in a New England marsh. Jill Swearingen, Invasive Species Coordinator, National Park Service .
