Chemical control is particularly effective when used in combination with prescribed burns (Avers et al. australis is causing serious problems for many other North American hydrophyte wetland plants, including the native Phragmites australis subsp. Phragmites is wind-pollinated; cross pollination with other plants is probably most common, but self-pollination or agamospermy may occur (Gucker 2008). The introduced common reed forms impenetrable monocultures and is capable of dominating wetlands with its increased canopy height within a few years (Rudrappa 2009). Fruit is a caryopsis with an adherent pericarp (Clayton et al. berlandieri (E. Common reed can be found in marshes, along rivers, at stream sides and canal banks. River Delta. 2008, Meyerson et al. restored P. australis wetlands (R1, R2, R3 and R4: … Avers, B., R. Fahlsing, E. Kafcas, J. Schafer, T. Collin, L. Esman, E. Finnell, A. Lounds, R. Terry, J. Hazelman, J. Hudgins, K. Getsinger, and D. Scheun. Other studies have indicated that it is possible to control invasive Phragmites in North America via purposeful livestock grazing and that this method has a high potential to suppress its impact on native plant communities (Silliman et al. It currently has 3 recognized subspecies: one European (subsp. Lake Michigan Field Station, 1431 Beach St., Muskegon, MI 49441-1098 (231) 759-7824 Leaves are blue green and usually darker than the native lineage (Swearingen and Saltonstall 2010). 2011. Rudrappa, T., Y.S. 2015). 2014). Ruiz, B. Steves, and J.T. (2014) reviewed Phragmites literature to see where gaps lie in management of this invasive species. The ligule is a ring of hairs averaging 1 to 2 mm (0.4 to 0.8 in) in length. ... Don’t rely on these characteristics alone to … The leaves and stems of Phragmites have poor nutritional value and few organisms feed on it in North America so replacement of native vegetation by the less nutritious Phragmites could have negative consequences for herbivores (Great Lakes Phragmites Collaborative). Trin. [4] However, other studies have demonstrated that it is associated with larger methane emissions and greater carbon dioxide uptake than native New England salt marsh vegetation that occurs at higher marsh elevations. maximus (Forssk.) Evaluating the Potential for Differential Susceptibility of Common Reed (Phragmites australis) Haplotypes I and M to Aquatic Herbicides. Phragmites australis, known as common reed, is a broadly distributed wetland grass growing nearly 20 ft (6 m) tall. 2014). is the most common and dominant species that contributes to pro-ductivity and landscape. 2010). 2014). Morgantown, West Virginia. 2006). Several tribes used also used it for building and weaving material from which they made mats, baskets, arrow shafts, flutes and rafts (University of Michigan 2016). [12] Ongoing research suggests that goats could be effectively used to control the species. australis and americanus: 1) the introduced Phragmites australis subsp. The ligule of the introduced lineage is typically less than 1 mm (0.4-0.9 mm) in length. Forest Health Technology Enterprise Team. In reed The investigated characteristics include plant composition structure, species diversity and community similarity in three kinds of Phragmites australis wetlands, i.e. 2006). 1994. Clayton, Phragmites communis var. As a wetland plant, Phragmites improves water quality by filtration and nutrient removal (Ailstock 2004). Notes on Phragmites australis (Poaceae: Arundinoideae) in North America. University of Michigan-Dearborn. Journal of Botanical Research Institute of Texas 1:385-388. 2006, Klein 2011). Once an area has been mowed, thatch should be raked, bagged and disposed of in an appropriate location to prevent seed dispersal and to allow sunlight to reach the soil surface (Avers et al. In Canada, despite its status as the nation’s “worst” invasive plant species, Phragmites is still found as an ornamental in some garden and landscape designs (MNR 2010). Phragmites australis is a wetland grass with a feathery plume at the tip of a tall, leafy stem, and is one of the most widely distributed flowering plants in the world. 4a). Great Lakes region nonindigenous occurrences, the earliest and latest observations in each state/province, and the tally and names of HUCs with observations†. 2008. Reed, Phragmites australis ssp. Phragmites australis (P. communis): Threats, management, and monitoring. The leaf sheaths of the introduced Phragmites adhere more tightly to the culm and persist as long as it remains standing, whereas those of the native lineage adhere less tightly and peel back eventually dropping off the culm once the leaf dies particularly at the lower nodes exposing the stem below (MNFI 2016, Swearingen and Saltonstall 2010). Water depths greater than 5 cm (2 in) generally prevent germination (Marks et al. australis. Visual effects, such as browning or withering of the plants, may not occur for several weeks (Avers et al. maximus (Forssk.) These near-monoculture stands can consist of 100% invasive phragmites. Kristin Saltonstall, Paul Peterson, Rob Soreng, and Bernd Blossey. 2006). It displaces native species including sedges, rushes, and cattails; and reduces wildlife habitat diversity, resulting in loss of food and shelter for native wildlife (Avers et al. americanus × P. australis subsp. In this study, we compared ecological characteristics of wetland vegetation in a series of restoration projects that were carried out in the wetlands of Yellow River Delta. This is easiest to see when they grow side-by-side (MNFI 2016). hispanicus (Nees) K. While long-term, low intensity grazing by goats and cattle has shown to decrease Phragmites density, it does not impact the root system. 2002). Nelson, L.A.M. The development and establishment of young plants of Phragmites communis. Suaeda spp. Seeds are primarily dispersed by wind in the fall and winter months (Fofonoff et al. Introduced Phragmites australis reproduces primarily clonally through the production and fragmentation of underground rhizomes, but is capable of sexual reproduction through seeds (Fofonoff et al. Other synonyms: Phragmites communis Trin., Phragmites communis var. Hazelton et al. flavescens Custer, Phragmites communis var. Martin, Rose M. and Moseman-Valtierra, Serena. Getsinger, K.D., L.S.

In rare situations, flooding may be used as a tool in combination with herbicide and fire to control Phragmites (Avers et al. Phragmites australis, known as Phragmites or common reed, is a non-native, invasive plant that dominates the land by out-competing surrounding native vegetation. 2007. 2014). Phragmites Australis Invasive Species Control and Management. Below ground, introduced Phragmites forms a dense network of roots and rhizomes that can extend downward over a meter (Swearingen and Saltonstall 2010). The leaf sheath is open. ... characteristics that help differentiate between the introduced and native forms of : Phragmites, based on observations of Drs. 2015).

Raspail, Oxyanthe phragmites (L.) Nieuwl., Phragmites altissimus (Benth.) None are currently an option available to land managers, because some prospective control agents may do greater damage to native lineage of Phragmites than the invasive (Silliman et al. Natural Areas Journal 14: 285-294. 2002). 2014). [citation needed] It can grow in damp ground, in standing water up to 1 m (3 ft 3 in) or so deep, or even as a floating mat. Chesier, J.C., J.D. berlandieri (E. Lemma are glabrous; lanceolate; 8–15 mm long; membranous; acuminate; with somewhat in-rolled margins. U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). 2006). The investigated characteristics include plant composition structure, species diversity and community similarity in three kinds of Phragmites australis wetlands, i.e. Phragmites australis was the predominant species in most parts of the floating mat of the relatively shallow area, whereas Z. latifolia was dominant under deeply inundated area as a deep-water species (Hung et al.

Which control methods should be used for a particular site will depend on the current conditions and management goals. Improper application of terrestrial formulations in aquatic environments may harm fish and macroinvertebrates and is a violation of federal and state laws. and stolons, see General Botanical Characteristics. Distinguishing native from non-native Phragmites australis can be challenging. Karst., Phragmites vulgaris (Lam.) This time period was chosen based on multiple trips to the field sites throughout summer and fall and on input from local land managers. 2011, Brown pers. Rhizomes of the native subspecies rarely exceed 15 mm in diameter and are a darker yellow than the introduced lineage (Swearingen and Saltonstall 2010). Phragmites australis management in the United States: 40 years of methods and outcomes. Potential for Biological Control of Phragmites australis in North America. Background European forms of Phragmites were probably introduced to North America by accident in ballast material in the late 1700s or early 1800s. 2005. Fernald, Phragmites communis ssp. 2006, Klein 2011). Phragmites australis is not listed in the Illinois Noxious Weed Act or the Illinois Exotic Weed act. ... australis is definitely an under-reported species in Minnesota, as we've seen it in a number of road ditches across the state not recorded at EDDMapS. This method has shown effective in small areas that previously received direct sunlight and could be ideal in locations where use of herbicide would impact nearby native plants (Great Lakes Phragmites Collaborative 2015). This type of plant that we can find in places with a lot of humidity is usually a good indicator that the soil has enough nutrients. Available: http://invasions.si.edu/nemesis/. ex Steudel (Poaceae), or common reed, is a worldwide perennial grass found in every continent except Antarctica. Bais. Phragmites produces various potentially interesting pharmacological compounds, including polysaccharides, anthocyanins, alkaloids (DMT, dimethyltryptamine; Kiviat 2010), but to our knowledge there is no current research focus in this area. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for P. australis with Dollimore method. comm. americanus (sometimes considered a separate species, Phragmites americanus), is markedly less vigorous than European forms. Literature reveals an abundance of herbivores on P. australis outside North America, particularly in Europe (Tewksbury et al. For more information on management of invasive Phragmites in the Great Lakes region, plase visit the Great Lakes Phragmites Collaborative. Culms of the introduced lineage are rigid and have a rougher texture than the native, which is usually smooth and shiny (MNFI 2016). It forms dense thickets of vegetation that are unsuitable habitat for native fauna. It is often necessary to do repeated treatments for several years to prevent any surviving rhizomes from re-sprouting (Avers et al. invasion by a non-native genotype of the common reed, "Common Reed. 2014). Indiana Department of Natural Resources (IN DNR). Common reed is a perennial grass that grows to 4 m tall in both fresh and brackish water. Flowering starts in late July (Fofonoff et al. 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. Massachusetts Department of Conservation and Recreation (MA DCR). 2007. 102(5): 805-812. Hazelton, E.L.G., T.J. Mozdzer, D.M. Both herbicides are available in separate formulas for application either on aquatic (wet) or terrestrial (dry) sites (Avers et al. Legates, K.H. australis hybrid along the Atlantic coastal plain of North America (Wu et al. Phragmites australis is one of the most widely distributed flowering plants in the world. The native lineage is usually found in fens, sedge meadow, river banks and shores, and the Great Lake shores (MNFI 2016). Blossey, B., M. Schwarzländer, P. Häfliger, R. Casagrande, and L. Tewksbury. Primary panicle branches divided; bearing spikelets almost to the base Clayton et al. Tewksbury, L., R. Casagrande, B. Blossey, P. Hafliger, and M. Schwarzlander. 2012. Illlinois does not list Phragmites australis on its “Aquatic Life Approved Species List” since some populations are not native to Illinois. Harman, and H. Williamson. Saltonstall, K., H.E. In addition to economic impacts, the introduced Phragmites poses a risk to human life and property. …common, or water, reed ( Phragmites australis) occurs along the margins of lakes, fens, … It is being provided to meet the need for timely best science. It is in flower from July to September, and the seeds ripen from August to October. Journal of Ecology 60: 585-610. comm. Results of one‐way ANOVA tests, following the multivariate omnibus test, evaluating differences in Phragmites … americanus from the introduced lineage Phragmites australis subsp. Effective control is likely to require multiple treatments using a combination of methods. Names and dates are hyperlinked to their relevant specimen records. These include Vernon, Osoyoos, … 2014). Along rivers and coastal shorelines, fragments of rhizomes transported from distant infested sites can settle in new spots and become rooted (Swearingen and Saltonstall 2010). The native Phragmites, is much less robust, typically occurring in low density stands, and is frequently found with other native plants but it can occasionally occur in very dense stands more typical of the introduced form when enriched with nutrients (MNFI 2016, Swearingen and Saltonstall 2010). 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. Carlton. ex Hicken, Phragmites fissifolius Steud., Phragmites hispanicus Nees, Phragmites isiacus (Delile) Kunth, Phragmites martinicensis Trin. 2016. Larval and Juvenile fish seem to be the most negatively affected by Phragmites (Great Lakes Phragmites Collaborative). Leaves are linear to lanceolate-linear; flat; drooping; leaf-blades deciduous at the ligule; 20–60 cm long; 8–32 mm wide with pointed tips (Clayton et al. It was used as a forage plant; the seeds were eaten in the absence of other foods (University of Michigan 2016). 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. The following characteristics should NOT be used to distinguish populations in southern areas (California to the Gulf of Mexico) where the Gulf coast type may be present as it is very similar in appearance to the introduced lineage (Swearingen and Saltonstall 2010). These herbicides are best applied in late summer/early fall after the plant has flowered either as a cut stump treatment or as a foliar spray (Avers at al. variegatus (Hitchc. Pedicels are filiform (Clayton et al. The sugary sap was heated into a ball and dried to be eaten like candy (University of Michigan 2016). Saltonstall, K. 2005. Burning after herbicide treatment reduces standing dead stem and litter biomass, which may help to encourage germination of native plants in the following growing season (Saltonstall 2005). Available http://www.hpwma.org/user/image/phragmitesfactsheet.pdf. 2015). Grant C-06-26. Furthermore, Phragmites alters wetland hydrology through increased evaporation and trapping of sediments, causing marsh soils to dry out (Avers et al. Flooding alone is not considered an effective control even though Phragmites is intolerant of persistent flooding (Avers et al. Fourn.) It is most often found on disturbed sites with altered hydrology, sedimentation, and nutrient enrichment. A Guide to the Control and Management of Invasive Phragmites. The erect stems grow to 2–6 metres (6 ft 7 in–19 ft 8 in) tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. However, Illinois DNR does find this species needs to be restricted and finds it inappropriate for import, possession, or culture since it is an invasive species (Illinois DNR, pers. Physical Characteristics Leaves: Blades flat; 0.39-1.5 inches wide; Flowers: Loose, branching cluster; Spikelets few-flowered; Stem: Hollow stem; 3-9 feet tall; 0.2-0.59 inches thick; Where Does it Grow? In Europe, Phragmites is grown commercially and used for thatching, fodder for livestock, and cellulose production (Swearingen and Saltonstall 2010). Hybridization of common reed in North America? It is of the upmost importance to apply these chemicals carefully at the recommended levels. americanus to species rank, Phragmites americanus, already accepted in … ex Steud. Plant Conservation Alliance, Weeds Gone Wild. americanus and berlandieri), though there is talk of raising subsp. It has been posited that low levels of sexual reproduction or differences in phenology were reducing the chances of naturally occurring hybridization between the two P. australis lineages (Saltonstall et al. Cryptic invasion by a non-native genotype of the common reed, Phragmites australis, into North America. Great Lakes Phragmites Collaborative. [Accessed 19 May 2016], ISSG.

[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. Spikelets cuneate; laterally compressed; 10–18 mm long; stalked with 6-10 mm long hairs on the stalks; breaking up at maturity (Clayton et al. [Accessed 18 May 2016]. 2003. ... ecologicalfactors affecting Phragmites australis … Some experts suggest that use of fire alone may stimulate rhizome growth and cause the remaining population to become more vigorous (Avers et al. When wetland hydrology, structure, and function are altered, wildlife is displaced. However, there are many overlaps in characteristics making it necessary to look at multiple factors when making a determination based on morphology. In fact, grazing at the wrong time of the year can increase Phragmites stem density (Great Lakes Phragmites Collaborative 2015). 2014). Characteristics: Fact Sheet. Lee, and H.P. As new information is available, discriminating morphological characteristics are updated at www.invasiveplants.net [ 26 ]. Third Edition. Pros and Cons of Common Reed Check federal, state and local regulations for the most up-to-date information. It is often necessary to do repeated treatments for several years to prevent any surviving rhizomes from re-sprouting (Avers et al. 2014). Kiviat, E. 2010. 2010). Antibiotic pollution has become a hot issue worldwide, which has toxic effects on plants and even threatens human health. [Accessed 23 May 2016]. Recent research using genetic markers has demonstrated that three separate lineages occur in North America – one endemic and widespread (native), one whose nativity … 2010, Saltonstall et al. However, other studies have shown little difference between Phragmites-dominated marshes and other plant communities in terms of birds’ abundance and diversity (Great Lakes Phragmites Collaborative). Evidence for natural hybridization between native and introduced Phragmites australis in Chesapeake Bay watershed. Livestock as Potential Biological Control Agent for an Invasive Wetland Plant. 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. Available: www.in.gov/dnr/files/PHRAGMITES2.pdf. Trin. Researchers at Cornell University have been studying several of these insects native to Europe as potential bio-control agents (Blossey 2007, Blossey et al. Michigan and Wisconsin have listed Phragmites as restricted, with regulations on possession and transport. Great Lakes Commission. 2006, Klein 2011). berlandieri (E. National Exotic Marine and Estuarine Species Information System. understanding phragmites control methods recommended management strategies further information Understanding Phragmites 3 The Problem 3 ... nonnative variety of phragmites (Phragmites australis), also known as common reed, is threatening the ecological health of Michigan wetlands and coastal shorelines. Glyphosate and imazapyr can be used individually or combined as a control strategy for Phragmites. comm. americanus. Covering cut stems with black plastic removes light and increases temperature which will eventually kill Phragmites below the plastic (Great Lakes Phragmites Collaborative 2015). australis is a hardy species that can survive and proliferate in a wide range of environmental conditions, but prefers the wetland-upland interface (Avers et al. Leaves of the invasive subspecies are a bluish gray-green, while those of the native lineage are typically a lighter yellow-green (MNFI 2016, Swearingen and Saltonstall 2010). Moldenke, Phragmites maximus var. Aquatic Invasive Species – Plants. [Accessed several times], Gucker, C. L. 2008. Clayton, W.D., M.S Vorontsova K.T. Burning also makes it easier to locate and re-treat areas of regrowth (Avers et al. In: Fire Effects Information System, [Online]. Culms of the native lineage are more likely to be red, typically around the nodes and where the leaf sheaths have been lost. Imazapyr should be applied to actively growing green foliage after full leaf elongation. It is a helophyte (aquatic plant), especially common in alkaline habitats, and it also tolerates brackish water,[3] and so is often found at the upper edges of estuaries and on other wetlands (such as grazing marsh) which are occasionally inundated by the sea. Annals of Botany 35: 1059-1072. 2014). 2014). Decomposing Phragmites increases the rate of marsh accretion more rapidly than would occur with native marsh vegetation. Phragmites australis has a moderate beneficial effect in the Great Lakes. Development of biological controls for Phragmites australis. PeerJ 2:e567. Bailey, Phragmites dioicus Hack. The species produces an abundant litter which can reduce the mobility of juvenile fish. Phragmites Management Sourcebook for the Tidal Hudson River and Northeastern States. Phragmites australis also had some traditional ethnobotanical uses for several Native American tribes (University of Michigan 2016). 2002. 2006). Crép., Phragmites vulgaris Britton, Sterns & Poggenb., Phragmites vulgaris var. Rhizome fragments may also be moved by heavy machinery (Swearingen and Saltonstall 2010). Panicles are oblong, purplish when young, straw colored at maturity; 15-50 cm long; 6-20 cm wide (Clayton et al. Mabille ex Debeaux, Phragmites australis var. Plant Guide.
