The leaves are l… Appearance Phragmites australis is a tall, perennial grass that can grow to heights of 15 ft. (4.6 m) or more. Where possible, flooding for extensive periods during the growing season can also be an effective method of control. established phragmites, complete eradi-cation may not be achievable. The flowers are produced in late summer in a dense, dark purple panicle, about 20–50 cm long. • www.phragmites.org Removing Phragmites infestations makes room for beautiful native plants, restores wildlife habitat and protects our infrastructure and outdoor recreation areas. MSU is an affirmative-action, equal-opportunity employer. [5], Common reed is suppressed where it is grazed regularly by livestock. Phragmites turns rich habitats into monocultures devoid of the diversity needed to support a thriving ecosystem. Phragmites australis, the common reed, is an aggressive, vigorous species which, in suitable habitats, will out-compete virtually all other species and form a totally dominant stand. Michigan State University Extension programs and materials are open to all without regard to race, color, national origin, gender, gender identity, religion, age, height, weight, disability, political beliefs, sexual orientation, marital status, family status or veteran status. These eventually help disperse the minute seeds. According to the Midwest Invasive Plant Network, invasive plants can affect your ability to enjoy natural areas, parks, and campgrounds. Phragmites australis (Cav.) In Europe, common reed is rarely invasive, except in damp grasslands where traditional grazing has been abandoned. Broad, pointed leaves arise from thick, vertical stalks. The leafy stems do not branch and shoots and leaves are stiff and sharp because of the high concentration of cellulose and silica content. How do I manage phragmites?

Recorded in southwestern Nova Scotia in 1910 By 1920s, in southern Nova Scotia, along the St. Lawrence River near Quebec City and at Under these conditions it either grows as small shoots within the grassland sward, or it disappears altogether. The Eurasian phenotype can be distinguished from the North American phenotype by its shorter ligules of up to 0.9 mm (0.04 in) as opposed to over 1.0 mm (0.04 in), shorter glumes of under 3.2 mm (0.13 in) against over 3.2 mm (0.13 in) (although there is some overlap in this character), and in culm characteristics.[1]. Foliage Leaves are 6-23.6 in. It displaces native plants species such as wild rice, cattails, and native orchids. Today, invasive Phragmites can be found across North America and Invasive plants can also increase the risk of flooding and soil erosion leading to cloudy water, lower water quality, and silted spawning beds. Background European forms of Phragmites were probably introduced to North America by accident in ballast material in the late 1700s or early 1800s. An aggressive, nonnative variety of phragmites (Phragmites australis), P. australis is cultivated as an ornamental plant in aquatic and marginal settings such as pond- and lakesides. [14], "Spartina alterniflora and invasive Phragmites australis stands have similar greenhouse gas emissions in a New England marsh", "Greenhouse Gas Fluxes Vary Between Phragmites Australis and Native Vegetation Zones in Coastal Wetlands Along a Salinity Gradient". To have a digest of information delivered straight to your email inbox, visit https://extension.msu.edu/newsletters. [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. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. The invasive subspecies of phragmites ( Phragmites australis) looks very similar to a native species ( Phragmites americanus ), and it is imperative that a stand be identified as invasive before implementing a management plan. Phragmites Australis Invasive Species Control and Management. Invasive Species - (Phragmites australis) Restricted in Michigan Invasive phragmites (also known as common reed) is a warm-season perennial grass with a rigid hollow stem and leaves that are flat, smooth, and green to grayish-green. However, through periodic management, it is possible to maintain phragmites infesta-tions at levels that allow for regeneration of native wetland plant communities and protection of fish and wildlife habitat. The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. It is commonly considered a non-native and often invasive species, introduced from Europe in the 1800s. This information is for educational purposes only. americanus (sometimes considered a separate species, Phragmites americanus), is markedly less vigorous than E… MNFI says that early recognition is critical because the plant stores energy underground in its extensive network of rhizomes; the older it is, the harder it is to control. The non-native subspecies was introduced to the east coast of the North America sometime between the late 1700s and the early 1800s, and has gradually expanded its range westward. (15-60 cm) long, 0.4-2.4 in.

Phragmites australis — Phrag, as she calls it — is pretty with its seed heads waving like feathery pennants in the Big Creek wetland, which drains into Lake Erie. Decomposing Phragmites increases the rate of marsh accretion more rapidly than would occur with native marsh vegetation. The presence of Phragmites, therefore, cannot only impact the quality of our environment but also the quality of our life style, which in these cases are inextricably linked. Phragmites. An invasive genetic strain, introduced from Europe or Asia, has expanded extensively along the St. Lawrence River in the last few decades but has been little studied on the estuarine portion. Phragmites australis, known as common reed, is a broadly distributed wetland grass growing nearly 20 ft (6 m) tall. Jeffrey W. Dwyer, Director, MSU Extension, East Lansing, MI 48824. ex Steud. Issued in furtherance of MSU Extension work, acts of May 8 and June 30, 1914, in cooperation with the U.S. Department of Agriculture. Phragmites australis is a widespread and aggressive invasive species. 2014). Mary Bohling, Michigan State University - Recognizing the non-native form of Phragmites early in its invasion increases the opportunity for successful eradication dramatically. [12] Ongoing research suggests that goats could be effectively used to control the species.

In Ontario, it is illegal to import, deposit, release, breed/grow, buy, sell, lease or trade invasive Phragmites (Phragmites australis subsp. americanus. common reed. It can grow to be over 15 feet tall and crowds out other plants, creating monotypic dense stands of these invasive plants (often with over 20 stalks per square foot). australis. Hikers, cyclists, and horseback riders all enjoy well-maintained trails, and invasive plants can grow over trails to the point that the path cannot be followed or can be difficult to navigate. (15-60 cm) long, 0.4-2.4 in. [9] Phragmites has a high above ground biomass that blocks light to other plants allowing areas to turn into Phragmites monoculture very quickly. Its aggressive colonisation means it must be sited with care. australis) are reeds that can grow up to 15 feet tall and in thick patches. Phragmites australis. However, another subspecies of Phragmites – Phragmites australis subsp. [10], Phragmites australis subsp. Learn about lakes online with MSU Extension. It is able to adjust its growing based on environmental conditions and can even survive stagnant, oxygen poor or salty conditions. The expansion of Phragmites in North America is due to the more vigorous, but similar-looking European subsp. Where conditions are suitable it can also spread at 5 m (16 ft) or more per year by horizontal runners, which put down roots at regular intervals. The stems are rigid, hollow and round and are about 1 inch in diameter and are usually 6-13 feet tall. Invasive Phragmites australis is changing many Michigan wetlands—and not for the better. Phragmites easily might be confused with the non-native invasive, Neyraudia. In the fall, phragmites begins to turn from its summer green, to yellow and ultimately tan as shown in the photo below. Grass family (Poaceae) Origin: Europe. Invasive Phragmites is a perennial grass that has been damaging ecosystems in Ontario for decades. If the conditions are right it can reach 15 feet. Trin. Although non-native Phragmites australis reigns supreme in terms of publicity, it is important remember that we also have stands of native Phragmites throughout the Great Lakes region. It grows in dense clusters and normally reaches 5 to 10 feet in height. Invasive Phragmites (European Common Reed) is an invasive plant causing damage to Ontario’s biodiversity, wetlands and beaches. [citation needed], In North America, the status of Phragmites australis is a source of confusion and debate. Show your Spartan pride and give the gift of delicious MSU Dairy Store cheese this holiday season! The native, subspecies americanus, and the invasive non-native introduced form, subspecies australis (sometimes referred to as haplotype M). Non-native Phragmitescan alter habitats by changing marsh hydrology; decreasing salinity in brackish wetlands; changing local topography; increasi… The flowers grow as dense branched clusters on the end of each stem that are open and feathery at maturity. The Michigan Department of Environmental Quality recommends controlling the invasive Phragmites by using an integrated pest management approach which includes an initial herbicide treatment followed by mechanical removal (e.g., cutting, mowing) and annual maintenance. It is commonly considered a non-native and often invasive species, introduced from Europe in the 1800s. Once it has become established, removal by hand is nearly impossible. Invasive phragmites forms dense stands of stems and can spread by both seed and sprouting from roots, rhizomes, and fallen stems. (1-6 cm) wide, flat and glabrous. These dense stands of phragmites can also limit access to water for recreation, block views, and pose safety concerns. Broad, pointed leaves arise from thick, vertical stalks. [7] The North American native subspecies, P. a. subsp. Ecology: Habitat: Phragmites australis subsp. For large areas with dense stands of invasive Phragmites, prescribed burning used after herbicide treatment can provide additional control and ecological benefits over mechanical removal. It may alsobe found in some tropical wetlands but is absent from the Amazon Basin … Phragmites australis blooms in the fall and is used by people and wildlife in many ways. Phragmites australis subsp. These ecotourism activities, support local economies across the Great Lakes basin, providing jobs for local citizens and tax base to support important government services on which many people rely. [8][6], Phragmites australis subsp. americanus – is actually native to parts of the U.S. and Canada and is quickly losing … Invasive non-native Phragmites australis is a perennial wetland plant that has quickly spread through Michigan marshes and wetland areas, robbing the fish, plants and wildlife of nutrients and space; blocking access to the water for swimming, fishing and other recreation endeavors; spoiling shoreline views; and posing a fire hazard. Early detection of small populations yields best management results. It offers shelter to many bird species and other animals. It appears to be nearly global in distribution in freshwater wetlands, it is found throughout the continental U.S.A. and is widely distributed in Wisconsin, although it appears to be most common in the southern part of the state, along the Great Lakes and in and around cities. Phragmites communis. Michigan Department of Environmental Quality. The invasive common reed (Phragmites australis subspecies australis) is a cane-like perennial grass that has rhizomes, forms large stands of clones, and grows from 12 to 16 feet tall. Suggested control efforts for phragmites vary by site and goals. Foliage Leaves are 6-23.6 in. When large-scale control is planned, any … Phragmites australis is of little value for grazing however, it plays a very important ecological role in wetlands by protecting the soil from flooding, filters the water and sometime becomes established in gullies to control soil erosion. americanus (sometimes considered a separate species, Phragmites americanus), is markedly less vigorous than European forms. In 2005, Agriculture and Agrifood Canada identified it as the nation’s “worst” invasive plant species. Native Phragmites stands have been found in a few New England marshes. australis (Common reed) is an invasive perennial grass that was transported from Eurasia and is causing severe damage to coastal wetlands and beaches in North America. It is not clear how it was transported to North America from its native home in Eurasia. The roots grow so deep and strong that one burn is not enough. This scenario is plausible for Phragmites australis which exists as distinct native and introduced subspecies in North America (P. australis americ-anus and P. australis australis, respectively) (Saltonstall 2002; Saltonstall et al. Appearance Phragmites australis is a tall, perennial grass that can grow to heights of 15 ft. (4.6 m) or more. It can spread through windblown seeds, soil transfer, animals or extensive over/under ground stems and rhizomes that will often re-sprout when broken. 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. November 22, 2013. 2004). Phragmites australis, known as Phragmites or common reed, is a non-native, invasive plant that dominates the land by out-competing surrounding native vegetation.The spread of invasive species is often the result of human activity but can also spread by wildlife. Phragmites grows in wetlands, ditches, and stream banks. Recent research using genetic markers has demonstrated that three separate lineages occur in North America – one endemic and widespread … They have a feather like-top and leaves that attach to the stem in an alternating pattern. Phragmites facts. It is considered invasive as it outcompetes all other plants and displaces wildlife as it becomes the 'top-plant,' at least in numbers, in a given area. In North America, the status of Phragmites australis is a source of confusion and debate. However, there is evidence of the existence of Phragmites as a native plantin North America long before European colonization of the continent. Species name: non-native Phragmites (Phragmites Australis subsp. More info at Ontario.ca; Difficult, but not impossible to stop. Gallic acid released by phragmites is degraded by ultraviolet light to produce mesoxalic acid, effectively hitting susceptible plants and seedlings with two harmful toxins. Invasive non-native Phragmites australis is a perennial wetland plant that has quickly spread through Michigan marshes and wetland areas, robbing the fish, plants and wildlife of nutrients and space; blocking access to the water for swimming, fishing and other recreation endeavors; spoiling shoreline views; and posing a fire hazard. [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. Best Management Practices In Ontario www.ontarioinvasiveplants.ca 6 Background Phragmites australis (European Common Reed) Native to Eurasia Introduced to Atlantic coast in 1800s (as contaminant in packing materials?) australis outcompetes native vegetation and lowers the local plant biodiversity. Phragmites australis, common reed, commonly forms extensive stands (known as reed beds), which may be as much as 1 square kilometre (0.39 sq mi) or more in extent. Distribution and Success of Native and Invasive Phragmites australis in Northern Michigan Abstract Phragmites australis, or common reed, is represented by several subspecies (haplotypes) in North America. It forms dense thickets of vegetation that are unsuitable habitat for native fauna. According to the Michigan Natural Features Inventory (MNFI), there are two subspecies of Phragmites australis present in Michigan. The Invasive Phragmites is an invasive perennial grass that now thrives in much of the wetlands around the Great Salt Lake and other marshes in northern Utah. August 30, 2018 – Etienne Herrick, USGS Great Lakes Science Center. Here we provide guidance to assist you in making this distinction. common reed. Invasive species can also turn an enjoyable stroll through the fields, woods, or wetlands while hunting into an uncomfortable trip through dense tangles of invasive species that are difficult or nearly impossible to push through and limit hunting opportunities.
