Common Reed Phragmites Australis (Cav.) Trin. Ex Steud. Grass Family (Poaceae)
FACT SHEET: GIANT REED Common Reed Phragmites australis (Cav.) Trin. ex Steud. Grass family (Poaceae) NATIVE RANGE Eurasia DESCRIPTION Common reed, or Phragmites, is a tall, perennial grass that can grow to over 15 feet in height. In North America, both native phragmites (Phragmites australis ssp. americanus Saltonstall, P.M. Peterson & Soreng) and introduced subspecies are found. Introduced Phragmites forms dense stands which include both live stems and standing dead stems from previous year’s growth. Leaves are elongate and typically 1-1.5 inches wide at their widest point. Flowers form bushy panicles in late July and August and are usually purple or golden in color. As seeds mature, the panicles begin to look “fluffy” due to the hairs on the seeds and they take on a grey sheen. Below ground, Phragmites forms a dense network of roots and rhizomes which can go down several feet in depth. The plant spreads horizontally by sending out rhizome runners which can grow 10 or more feet in a single growing season if conditions are optimal. Please see the table below for information on distinguishing betweeen native and introduced Phragmites. ECOLOGICAL THREAT Once introduced Phragmites invades a site it quickly can take over a marsh community, crowding out native plants, changing marsh hydrology, altering wildlife habitat, and increasing fire potential. Its high biomass blocks light to other plants and occupies all the growing space belowground so plant communities can turn into a Phragmites monoculture very quickly. Phragmites can spread both by seed dispersal and by vegetative spread via fragments of rhizomes that break off and are transported elsewhere. -
Decadal Changes in Phragmites Australis Performance in Lake Eyre Supergroup Spring Communities Following Stock Exclusion
Decadal Changes in Phragmites australis Performance in Lake Eyre Supergroup Spring Communities Following Stock Exclusion Simon Lewis1 and Jasmin G. Packer2,3 Abstract Many ecosystems around the world are vulnerable to competitive expansion by cosmopolitan colonisers (e.g. Phragmites australis, common reed) where human-mediated disturbance increases nutrient levels. Yet our understanding of the long-term dynamics within vegetation communities once this disturbance has been excluded, and how best to reduce the residual negative effects, is limited. The Great Artesian Basin (GAB) springs in South Australia offer a useful case study of vegetation responses post-disturbance because they form a collection of semi-independent ecosystems with a rich management history, from burning by Aboriginal people to pastoralism and stock exclusion from some springs since the 1980s. This paper presents a case study based on 35 years of observational data on the response of P. australis and other wetland vegetation at protected GAB springs of the Lake Eyre supergroup. The case study aims to understand how naturally present P. australis per- forms within GAB spring communities following stock exclusion. Where P. australis was present at the time of stock exclusion, it became monodominant across the main pool of several springs within the first decade, and expanded throughout the spring tail during the second and third decades. The endangered salt pipewort (Eriocaulon carsonii) appears to have been reduced in distribution and abundance where P. australis became monodominant. However, in two promising cases, P. australis dominance waned after 30+ years of stock exclusion and, in another, has not colonised a spring free of P. -

A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Phragmites australis (Cav.) Trin. ex Steud. Common reed Family: Poaceae Range: A western biotype is native throughout the western United States and adjacent Canada. A Gulf Coast biotype is found from Florida across to southern California, although it is not known if this biotype is native or introduced from Mexico and Central America. A non-native biotype has been found throughout the contiguous U.S. and adjacent Canada. Habitat: Wetlands, riparian areas, shores of lakes and ponds. Origin: The non-native biotype was introduced from Europe, apparently via ships’ ballast. There are also native biotypes of Phragmites australis. Impacts: Forms dense stands in wetlands and reduces native plant biodiversity. Western states listed as Noxious Weed: Oregon, Washington Common reed is a rhizomatous perennial grass to 15 ft tall, usually found growing in water or along the shores of streams, ponds, and lakes. The leaves are typical for a grass, but large: up to 1.5 inches wide and 8 to 16 inches long. The ligule (at the junction of the leaf blade and the stem) is tipped by a fringe of hairs, while the blades and sheaths are smooth. -

Response of Mosquitoes Associated with Estuarine Wetlands to Bushfire in Australia
Journal of the American Mosquito Control Association, 37(2):101–105, 2021 Copyright Ó 2021 by The American Mosquito Control Association, Inc. SCIENTIFIC NOTE RESPONSE OF MOSQUITOES ASSOCIATED WITH ESTUARINE WETLANDS TO BUSHFIRE IN AUSTRALIA 1,2 3 3 CAMERON EWART WEBB, RAFFAELE CATANZARITI AND STEVEN HODOSI ABSTRACT. The response of mosquitoes to bushfire is poorly understood. During the 2019–20 summer, many regions of Australia were impacted by devastating bushfires. An area of estuarine and brackish-water wetlands alongside the Georges River, Sydney, New South Wales, was burned in January 2020. Mosquito populations within Downloaded from http://meridian.allenpress.com/jamca/article-pdf/37/2/101/2855383/i8756-971x-37-2-101.pdf by guest on 28 September 2021 the area were monitored as part of the local authority’s mosquito management program, providing a unique opportunity to record the response of key mosquitoes of pest and public health concern to bushfire. Ground pools within a tidally influenced swamp oak forest dominated by Casuarina glauca and associated wetlands dominated by Phragmites australis and Bolboschoenus spp. had been identified as suitable habitat for a range of mosquitoes, including Aedes alternans, Ae. vigilax, and Verrallina funerea. Surveys of immature stages of mosquitoes within recently burned habitats inundated by tides demonstrated that mosquito eggs survived the direct and indirect impacts of fire and immature stages successfully completed development as reflected in concomitant changes in adult mosquito populations following the bushfire. This unique observation has implications for mosquito management following bushfire in Australia and internationally.

There are 2n = 36, 48, and 54 chromosomes (Duke 1998, Gould 1975, Harrington 1964, Uchytil 1992, Welsh and others 1987). Range.—Common reed occurs in every state in the Continental United States except Arkansas (probably present but undocumented), in Puerto Rico (Natural Resources Conservation Service 2003), southern Canada, and Mexico. In fact it is found on all continents except Antarctica (Harrington 1964). It is native to the United States and is known from the archeological record. However, genetic analysis has shown that more aggressive European genotypes have replaced the native genotype in much of the former American range and have invaded new areas (Blossey 2002). Ecology.—Common reed is a warm-season grass that starts its growth after the last frost has occurred but remains green until frost in temperate areas (Uchytil 1992). Wide climatic tolerance is indicated by its range that stretches from the tropics to cold temperate areas and habitat from sea level to elevations of at least 1,980 m (Harrington 1964, Welsh and others 1987). Common reed typically forms pure stands that contain up to 205 stems/m2 (Uchytil 1992). In Gulf Drawing source: Britton and Brown 1913 Coast marshes, it is often codominant with Spartina cynosuroides (L.) Roth. (Duke 1998). General Description.—Common reed is also The species grows on the shores of streams and known as giant reed, giant reedgrass, roseau, lakes, and in marshes, both fresh and brackish. -
Reedbeds Published on Buglife (
Reedbeds Published on Buglife (https://www.buglife.org.uk) Reedbeds Introduction Reedbeds are wetlands dominated by stands of one plant, the Common reed (Phragmites australis). The majority are freshwater, but reedbeds are also found in brackish and tidal waters. Common reed is an active coloniser of wet ground or open water and reedbeds form a transition stage in the eventual succession to woodland. In tidal areas or sites which are subject to regular freshwater flooding, a reedbed may persist in a relatively stable state unless there is heavy siltation. Elsewhere, the accumulation of dead vegetation and litter will result in the gradual drying of the bed, allowing invasion of carr, scrub or woodland species. All stages in this development provide important habitats for invertebrates; the areas of lowest invertebrate interest being those of open water. Five British Red Data Book invertebrates are closely associated with reedbeds including Reed leopard moth (Phragmataecia castanaea) and a rove beetle Lathrobium rufipenne. In East Anglia, more than 700 species of invertebrate have been recorded from reedbeds, 23 of them Red Data Book. 40 species in four Orders - Hemiptera, Lepidoptera (moths only), Coleoptera & Diptera - are known to feed only on reed, with a further 24 insects feeding partly on reed during their life cycle. A wide range of invertebrates are also associated with reed even if they do not feed directly on it. These include predators (mainly beetles and spiders) and parasites of the reed-feeding invertebrates which live in the stems, including gall-forming flies and solitary wasps. The solitary bee Hylaeus pectoralis nests in vacated cigar galls on reed. -
