Reed canarygrass regrows following cutting, mowing, or other types of damage Raunkiaer [242] life form: plant community suggests its invasion was not recent [42]. or a dominant species [94,97,197,220,235,270], cultivation, different strains of reed canarygrass vary greatly in vigor of growth, leafiness, seed retentioin, seed production, and resistance to drought [306] which may influence its invasiness. rice cutgrass (Leersia oryzoides) [68,244], and nonnative pasture grasses [18,49,94,103,114,159]. than 10 to nearly 1,000 seeds/m² [172]. Information on state-level noxious weed status of plants in the United States is river island" [15]. persists and may spread in plant communities of various successional stages, from early [18,66,71,79,156,204,207,228,239] description: This description covers characteristics that may be relevant to fire Postfire persistence and spread: On sites where reed (e.g., avoid road building in wildlands [280]) Their cover was temporarily reduced when inundation lasted for more than 6 weeks, but they recovered before the next flood season [118]. The stem is hairless and stands erect. In Oregon, reed canarygrass grows substantially in the spring before flood waters recede did not differ in variable light levels (i.e., full sun, partial shade, and full shade) [236]. the axils of the leaves [63]. Native populations of reed canarygrass that have not been exposed to gene flow from nonnative Germination and seedling establishment in reed canarygrass improve with increased light levels; however, reed canarygrass seedlings may establish in shade. Reed canarygrass drought tolerance Just keep it maintained – as you say, planted to clover and then mowed regularly) and you should be fine. If it is Canary grass it is pretty easy to control. available at Plants Database. canarygrass is well established, it may persist and grow rapidly after fire [1,69,260,279], AUTHORSHIP AND CITATION: However, in 2003, 5 years after fire was reintroduced, reed canarygrass occurred in 10% of plots in dry-mesic gravel prairie and in 20% of plots in mesic gravel prairie [24]. United States, and increasingly in eastern North America [170]. A review by Maurer and others [195] suggested that reed canarygrass is invasive because of high energy allocation to reproduction, clonal growth, long growing period, rapid growth, high productivity, and a broad tolerance to environmental variability. In the greenhouse, reed canarygrass' aboveground biomass was reduced in shade when compared to reed canarygrass grown without shade. to late succession [66,93,144]. Studies from Minnesota [1] and Tennessee [69] indicate Reed canary grass is a coarse, cool season grass that grows 2 - 6 feet tall. RCG grows so thick that it restricts flow in a waterway and causes sediment and organic matter to fall out of the water column and accumulate on the bottom of the waterway. Germination rates of reed canarygrass are consistently higher for seed germinated in light than in dark [44,92,117,173,180,289], ([46,301,306], review by [7,148]) Fire had little effect on reed canarygrass relative abundance in the saltgrass community. IMPORTANCE TO WILDLIFE AND LIVESTOCK: In 2006, an early March prescribed fire was followed by a 10 May application of glyphosate. more effective when timed to take advantage of reed canarygrass' vulnerable phenological stages Vose [289] described germination for various strains of North American strains [152]. In one study from Manitoba, Canada, reed canarygrass occurrence was negatively associated with Seed dispersal: Reed canarygrass seed is passively dispersed [92] by gravity fire: Established reed canarygrass typically persists [1,69,105,260] [250] that may be as wide as 3 feet (1 m) across [283]. GENERAL DISTRIBUTION: Surface rhizome and/or a also occurs in fens and bogs, particularly in the Rocky Mountains [252] One report from the Great Plains [117] and another from New Jersey [171] Mauer and others [195] speculated that Experimental plots were burned in May 2001 to remove dense litter and then sprayed with glyphosate on 23 August 2001. [97,283]. In Washington, 16% of reed canarygrass seeds submerged in a column of water for 3 months germinated, and 7% of seeds submerged for 12 months germinated. growth may be adversely impacted by extended periods of flooding [26,47] A few reports indicate that reed canarygrass occurs In a New Jersey tidal wetland, estimated soil seed bank densities ranged from about 100 to over 5000 seeds/m² at a depth of 2 cm [172]. [251,252,257,283], and the Great Lakes states [245,283]. Disturbed wetlands are most susceptible to invasion. Reed canarygrass may reach 4 to 5 feet (1-2 m) tall within 2 to 4 years [204,301] June ([157], review by [119]). from the nonnative types, discrimination between the two types is difficult deposits of varying mineral and organic content. Where reed canarygrass was invading an oak savanna in Wisconsin, early spring fire appears to have "accelerated its spread" [105]; however, late spring burning had negative impacts on reed canarygrass. Additionally, morphological variability makes it difficult, if not impossible, to distinguish between native and nonnative populations [205]. [64,83,87,112,113,194,241,268,298]. Additionally, past and present use of reed canarygrass for forage and erosion control may frustrate attempts to control it in wildlands [89]. with black plastic or fabric may kill small stands of reed canarygrass [5,105,119,177,279], A few publications suggest that reed canarygrass may occur in oak (Quercus spp. Phalaris arundinacea. When considering fire as a treatment option for reed canarygrass, managers should be aware of its potential for postfire establishment and spread (see Plant response monoculture (97% relative cover) of reed canarygrass. invasion by nonnatives, and disease (review by [93]); Reed canarygrass has been observed in sphagnum (Sphagnum spp.) this study [279]. palatability may be reduced by the coarseness of its leaves. The first of Howe's studies [126,127] investigated the seasonal effects of fire in agricultural fields where vegetation was removed and tallgrass prairie It occasionally occurs as a transient species in early succession [307] increases in frequency of nonnative grasses, including reed canarygrass, corresponded to decreases in frequency of numerous herbaceous species common to the island. ([1], review by [251]). clumps will maintain the planted native sedge meadow [260]. One review indicated that reed canarygrass grows most rapidly during the cool spring months [283]. Reed canarygrass establishes in recently abandoned farmlands in the early stages of succession ([18,79], review by [239]). In Iowa [121] and Ohio [63], initiation of the inflorescence Rates of carbohydrate storage varied from year to year. Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). and river islands [15,243,293]. Riparian plant community publications from Idaho [6] and Montana [97] In either December 2002 or May 2003, sites were seeded with a mix of graminoids and forbs containing 33 species. In North Dakota, 1 stem of reed canarygrass produced 120 seeds [266]. and by monitoring several times each year [138]. Dates for reed canarygrass fruit maturation are variable (see Table below). reed canary-grass indicated that reed canarygrass growth may be adversely impacted by drought (see Seedling establishment and plant growth). When fire is used as part of an integrated management plan, reed canarygrass' response to fire may be influenced by the timing and sequence of other treatments (see Use of prescribed fire as a control agent). Under Control: Reed canarygrass is difficult to control because it has vigorous, rapidly spreading rhizomes and forms a large seed bank [69,105,232,240]. In a "large" stand of reed canarygrass in Oregon, tiller production was greater in plots after Belowground: Reed canarygrass spreads by creeping rhizomes [99,112,131,143,194,214,222]. and up to 1 year if it is not totally submerged (review by [277]). These ecotypes look identical but vary in their growth. However, a few publications regard reed wetland restoration [240]. Flower stem production occurred when daylight increased [51]. Throughout its North American range, reed canarygrass occurs in riparian forests A study in Wisconsin found that native shrub and tree survival could be improved for planted native wetland communities in stands of reed canarygrass should be carefully monitored [168]. pathways, further complicating its successional role. sites where natural hydrological regimes had been altered. months[5] = "June"; in monotypic stands of reed canarygrass in a wetland in northeastern Tennessee, reed canarygrass seedlings were growing from gaps in the litter on burned plots [69]. reed canarygrass may begin to grow in late winter (review by [5]). In Tennessee, reed canarygrass Because no morphological characteristics clearly distinguish the native reed canarygrass In the eastern Great Plains area, reed canarygrass rhizomes survived spring herbicide applications; however, late October and early November application killed reed canarygrass difficult to manipulate. is not agronomically superior to other forage grasses. canarygrass generally produces seed in early summer [173]. developed [102]. low temperatures range from 9.5 °F (-12.5 °C) [216] to 40.5 °F (4.7 °C) [69,182] in the coldest month, and average annual high temperatures range from 59.2 °F (15.1 °C) [182] to 70 °F (21 °C) [69,216,284] in the warmest month. and Great Lakes states [51,178,195]. growth may be adversely impacted by extended periods of drought [139]. Reed canarygrass seed was found on feet and feathers of waterfowl. Conversely, Merigliano [204] Reed canarygrass may establish on sites where fire is reintroduced after having been excluded for years. by high-severity fires in some plant communities. In an oak savanna in Wisconsin, hand-pulling controlled reed canarygrass when treatments were carried out 2 to 3 times a year over a 5-year period [105]. In wetlands of the northcentral United States and the Great Lakes area, reed canarygrass commonly (see Seasonal development and In Ohio, it occurred in a forested bog [206]. Use of prescribed fire), although reed canarygrass may and may have facilitated its spread in North America [169]. On sites inundated long enough, stands of reed canarygrass provide cover for common muskrat [97]. However, newer varieties of reed canarygrass are equal in quality to other cool-season grasses when h… and may prefer sites that experience periodic flooding Reed canarygrass may produce wind-borne embers when stands are burned (Eggers personal A variegated type, Phalaris arundinacea var. It may contain some native plants [, Oregon to Montana, south to California, Arizona, New Mexico; may occur in eastern Washington, Reed canarygrass codominates this alliance with other emergents such as common spikerush, Baltic rush (, reed canarygrass seasonally flooded herbaceous alliance, eastern Montana, within the Great Plains bioregion [, Delaware Water Gap National Recreation Area; boundary of New Jersey and Pennsylvania, Delaware Water Gap National Recreation Area, Silver maple dominates the canopy and reed canarygrass forms dense stands in the herbaceous layer [, Black cottonwood, willow, and red alder (, silver maple with reed canarygrass forest, Silver maple dominates the overstory, red-osier dogwood is common in the shrub layer, and reed canarygrass dominates the herb layer. Plants Database provides a map of reed canarygrass' In an experimental garden, 1 square meter of loam contained about 383 feet (117 m) of rhizomes [219]. followed by herbicide application to kill seedlings, may deplete the seed bank and thus limit reed canarygrass' potential to reinvade sites undergoing restoration. In an experimental field, tillering began within 1 month after seedlings emerged, and average tiller production increased from 0.5 tiller/seedling during the 1st month of growth, to 5.5 tillers/seedling after 10 weeks [46]. Successful strategies require a multiple-year commitment including long-term maintenance. Other common names for the plant include gardener's-garters in English, alpiste roseau in French, rohrglanzgras in German, kusa-yoshi in Japanese, caniço-malhado in Portuguese, and hierba cinta and pasto cinto in Spanish. Palaton reed canarygrass is a low alkaloid variety that is a leafy, high yielding, long lived perennial. Reed canary grass has been planted throughout the U.S. since the 1800s for forage and erosion control. Reed canarygrass stems and leaves tend to smother annual plants and block the sunlight. Allard and Evans [3] indicated that reed canarygrass' North American distribution is likely a silver maple (Acer saccharinum) [15,203,293], Pure reed canarygrass stands provide an outstanding outlet for manure applications during … [71,120] or where it becomes shaded [66]. Reed canarygrass Reed canarygrass seed in the soil seed bank may remain viable after periods of inundation [19,199], but seed floating in the water may lose viability relatively quickly [45]. indicated that reed canarygrass seed is also dispersed by wind, although details were not provided. This alliance occurs in sloughs and marshes bordering secondary channels of wide floodplains. [228], on newly created gravel bars [15,204], An invasive plant guide from Alaska claims that Cultural control: Shading has been suggested as a control for reed canarygrass [5,119,149,236]; however, reed canarygrass' response to shade is not well understood [236]. bogs, particularly in the canary grass Germination: Reported germination rates in reed canarygrass are variable [44,92,117,173,178,180,289]. preference for well-lit sites. but may not prefer it over native plants in many situations (see Shade tolerance). In a dense stand of reed canarygrass in Minnesota, researchers did not get a "good burn" during a June prescribed fire, which they attributed to the high moisture content of the litter [240]. )-dominated woodlands in the Pacific Northwest (review by [6]) and Wisconsin [106,202]. (Elaeagnus angustifolia) [30,223]. Reed Canary Grass (RCG) is an aggressive, invasive species that crowds out native vegetation. On an experimental site in Ohio, reed canarygrass rhizome production peaked in June and declined through August. Reed canarygrass has been bred for cultivation and at least 11 cultivars have been allowing cool-season plants, such as reed canarygrass, to persist and even [41,51,56,73,166,244], Stand structure: Reed canarygrass forms large clumps Reed canarygrass' spikelets are 3-flowered [298] and occur on a narrow panicle 2 to 12 inches (5-30 cm) long [64,83,112,187,194,222,268]. months[11] = "December"; This is a major habitat type in western Montana and a minor type in eastern Idaho and central and eastern Montana [, Pecos, Rio Grande, and San Juan river basins in New Mexico, Reed canarygrass constitutes ≥ 90% cover. winter-hardy [283], although different strains may be less Seed production: Reed canarygrass seeds used in germination studies had an average length of 4.15 mm In riparian areas, reed canarygrass may occur with a mix of woody species and forbs, in addition to the graminoids previously described [15,150,197,223,293], In the quackgrass community, reed canarygrass relative abundance increased after both fires; however, it was less abundant in burned blocks than expected in the year when spring flooding was "extensive". A Wisconsin marsh had been dominated by reed canarygrass, but it was nearly eliminated following SITE CHARACTERISTICS: In Oregon, within 1 year of restoring historical flooding regimes to a slough, reed canarygrass cover was reduced by as much as 10.7% [137]. extensively throughout Europe; cultivation in North America was first reported in New England in the 1930s (using ribbon grass) [4]. so they are difficult to apply to wildland conditions. >50% [235] to 100% of the vegetation cover [94,97,159,197,220]. claim that lack of palatability in reed canarygrass is the most frequently cited reason why it [310], sweetgale (Myrica gale), and smooth sawgrass Glyphosate products, approved for use in aquatic environments, have been used to kill reed canarygrass [1,69,148,161,177,240,260,305] In northern Illinois, reed canarygrass established in mesic prairies when fire was reintroduced after being excluded for at least 22 years (1978-1998). Several attributes may contribute to reed canarygrass' invasiveness in North America. may not improve with increased nutrients [67]. Wetland fires may be difficult to conduct in monotypic stands of reed canarygrass because it remains green into the fall (reviews by [119,277]). forage for snow geese when compared to 3 other pasture grasses and 2 In New Jersey, reed Another study also observed improved native plant establishment when sethoxydim was applied after Following are descriptions of five studies in which prescribed fire was integrated with other The authors recommended further study of the interactive effects of burning and flooding on reed canarygrass abundance [200]. It grows in roadside ditches, river dikes, shallow marshes, wetlands and meadows. Publications from the inland Northwest [94,97,205], It can outcompete most native species in natural wetlands and presents a major challenge for restoration in wetland mitigation efforts. Reed canarygrass cover may reach 97% and can completely displace Columbian sedge [, Nonnative grasses, Kentucky bluegrass, redtop (, Reed canarygrass monoculture that resulted from seeding reed canarygrass, Pacific willow average cover may reach 59% and reed canarygrass average cover may reach 60% [, Reed canarygrass maintains nearly 100% cover. rehabilitation activities, Minimize the use of retardants that may alter soil nutrient availability, such and may be native to Pakistan and Kashmir [2]. Immediate fire such as forested wetlands, seldom burn [183]. cordgrass (Spartina pectinata) [41,56,243,294]. A variety of wetland and upland birds [97,151,164,191], Both dry storage and cold-stratification have enhanced germination in reed but for how long is unclear. and in some instances it may spread [105]. a study of historical documents and herbaria records of reed canarygrass collected in the inland northwestern United States prior to widespread European settlement in that area [205]. Vegetative regeneration. It is a common associate of other graminoid plant communities dominated by reedgrasses This research indicates reed canarygrass may be reduced by spring burning and increased by summer burning, but summer burning is unlikely to favor reed canarygrass to the point where it becomes dominant in areas previously dominated by warm-season grasses. In some parts of the world such as America and Canada, the species may be grown for livestock forage. Fire timing may influence the outcome of reed canarygrass control treatments [168]. Most North American floras treat reed canarygrass as a native species [14,50,83,87,111,113,187,192,298]. ([148], review by [8]) may be hindered or impractical on many sites. In the Canary Islands, Italy and North Africa, Phalaris canariensis is used as food. Animals may provide long-range seed dispersal of reed canarygrass and help deposit seed in sites more favorable to germination than seed randomly dispersed by water [288]. rhizomes completely [161]. fall and the following spring [63]. This misconception is in part due to the high alkaloid content of native varieties and the practice of delaying harvest until reed canarygrass is mature. The coarse, erect stems may reach a … In an Oregon riparian forest, increasing reed canarygrass abundance was correlated with decreasing species richness (R²=0.2455) and understory species diversity (R² =0.327) in stands older management activity, Detect weeds early and eradicate before vegetative spread and/or seed dispersal, Eradicate small patches and contain or control large infestations within or adjacent var months = new Array(12); Northwest, reed canarygrass seed matures in late July and early August. Treatments included herbicide alone and herbicide followed by mowing, plowing, or prescribed fire. and to a lesser degree, dogwood (Cornus spp.) and are dispersed almost as soon as they ripen ([90,301,306], reviews by [12,119,257]). Then the site was seeded with a native sedge and forb mix. [108,299]. effect on plant: Reed canarygrass is top-killed by fire. General habitat: In North America, reed canarygrass occurs in marshes, wet meadows and prairies, lake shores, stream banks [9,15,87,131,142,158,187,195,241,250,252], reduce reed canarygrass cover in a monotypic stand that had been planted more than 35 years before. Seeding and planting of native species have been used in conjunction with other treatments to Many natural and anthropogenic factors influence floodplain succession, including flooding, wildfire, windthrow, timber harvest, flow alteration, ungulate browsing, more effective at controlling reed canarygrass if done in conjunction with other treatments such as mowing and native plant seeding [105,177]. Seed banking: Available evidence suggests that reed canarygrass forms a soil seed bank grasses in general burn more readily and usually support much more intense and continuous fires Additionally, some evidence suggests that dense, tall stands of reed canarygrass small mammals [97,124,272], amphibians [81], Substrate and water chemistry: In North America, reed canarygrass occurs on a variety of soil textures from clay to sand [34,64,94,97,202,220,264]. One laboratory study [139] In another palatability test, reed canarygrass was preferred Studies have documented common muskrats [272] and voles [124] leaf axils of aboveground shoots [63]. [1,69,105,119,240,279,305]. Wild populations likely share the same variability because they are thought to be an assemblage of introduced strains (see Native Status in North America). Survival of planted material was highest in herbicide-burned plots and herbicide-plowed plots. (2010) that investigate differential effects of fire season without other, confounding treatments. Potential strains may no longer occur in North America. invading wetlands by constructing erosion screens and catch-basins around wetlands adjacent to In monotypic stands of reed canarygrass in the Czech Republic, all rhizomes and over half of the using flooding for reed canarygrass control may be costly and water levels but typically persists longer [66,71,221,228]. [306]. In the greenhouse, Hydrological manipulation: Reed canarygrass may establish by seed and/or rhizomes following drawdown, even on sites treated with herbicide [232]. Reed canary grass is 2-9 foot tall. literature. there has been little documentation of these effects. Menges and Waller [203] concluded that reed canarygrass had a particularly if it occurs in the summer [153]. (Calamagrostis spp.) depending on the strain [306] but may produce as much as 500 pounds/acre [301]. 2002 to remove litter. Reed canarygrass is common in the northern half of the United States and southern third of Canada [76], especially in the Pacific Northwest Peatlands in Wisconsin have been The following is a summary of available literature on reed canarygrass phenology from various parts of North America. It typically occurs in soils that are saturated or nearly saturated for most of the growing season. If used independently, mechanical control typically produces short-term reed canarygrass control at best ([95,148,240,301], review by [133]). In a monotypic stand These create a thick, impenetrable mat at or directly below the soil surface. Fire may be effective on sites where fire-adapted native species are present in the plant community or seed bank [133,260], or where these are planted as part of the treatment. Management strategies used for reed canarygrass control include mowing, herbicide, grazing, cultivation techniques, fire, shading, and flooding (review by [168]). Results from field and laboratory studies indicate that shade may reduce reed canarygrass' aboveground biomass but not its tiller production (see Shade tolerance). Decisions to control populations of reed canarygrass may be based on its A native mix of graminoid and herbaceous species was seeded on the site shortly after the fire. particularly flooding in the summer [153]. The following table shows characteristics of habitat types and plant communities in North America where reed canarygrass is a dominant, codominant, or characteristic species. plots but increased in summer-burned plots, although they did not become dominant. Reed canarygrass is considered The lead ligule is membranous and long. and several studies indicate that light availability may influence reed canarygrass germination [173,179,180].
