BLM PHYSIOGRAPHIC REGIONS :
Bigleaf aster is a native perennial forb. It is rhizomatous and colonial, often forming dense patches measuring up to 19 Ã 16 feet (5.8 Ã 5 m) . It has basal and cauline leaves. The large basal leaves are borne on short, sterile shoots. They are thick, firm, and have long petioles. The cauline leaves become smaller and stalkless as they ascend the inflorescence. The inflorescence is a corymb that reaches heights of 5 feet (1.5 m). The corymb has sticky, glandular hairs. Flowers have both ray and disc florets. The fruit is a nutlet and is ellipsoid to oblanceolate, ribbed, and pubescent. The seed has a pappus [42,54,57,58,82,85,103].
Physiology: Bigleaf aster can persist in high light environments because of its ability to control stomatal conductance. Increases in evaporative loading, created in high light environments, initiate stomatal closure to prevent excessive water loss .

Fire Management Considerations
Bigleaf aster's fire-adaptive traits suggest that the use of prescribed fire that opens the canopy is beneficial for the species.
Bigleaf aster may aid in preventing wildfire ignition and slowing fire spread. Hogenbirk and Sarrazin-Delay  assessed the possibility of planting less-flammable vegetation including bigleaf aster in fire-prone areas, around property, or in fire-sensitive natural areas to reduce the spread of human-caused fires in herbaceous communities of northern Ontario. Bigleaf aster was 1 of 3 species that had the lowest potential ignitability.
Plant Response to Fire
Bigleaf aster responds favorably to fire, regenerating vegetatively from rhizomes and root crowns soon afterwards [3,17,18,19,20,65]. It often increases in abundance and produces more flowers after fire [2,70,99,104,106,112]. It is a dominant herb after wildland and prescribed fires, is present before and after burning, and is found on burned and unburned areas [1,2,4,9,59,70]. Sidhu  stated that the postfire response of bigleaf aster is affected more by fire intensity than by the time of burning. The greater the fire intensity, the greater the negative effect on bigleaf aster . Research reveals, however, that bigleaf aster is capable of vegetative regrowth after low- and high-severity fires.
Smith  stated that the greatest abundance of bigleaf aster occurred after low-severity surface fires. "Vigorous" growth was observed the 1st growing season following a spring low-severity prescribed fire on eastern white pine forests in New Hampshire and for 3 postfire growing seasons after a spring wildfire in mature red and eastern white pine stands in northeastern Minnesota [6,19,20]. Bigleaf aster density increased immediately following a spring wildfire in a jack pine forest in northeastern Minnesota, making it 1 of the most common herbs on the site. The fire had varied intensities, including areas with intense crown fire and low-severity surface fire. The forest floor was still moist, with the fire occurring in May, so areas that did experience high-severity fire had only the upper portion of the forest floor burned [14,52,75,76].
Bigleaf aster sprouts were recorded within weeks and months after high-severity wildfires on alvar woodlands (white spruce, quaking aspen, northern white-cedar (Thuja occidentalis), and balsam fir (Abies balsamea)) and on old-growth red and eastern white pine forests in Ontario [18,65,97].
Bigleaf aster can be reduced by fire . The percent cover of bigleaf aster declined after both low- and high-severity prescribed burns on jack pine forests in northern Ontario, but bigleaf aster maintained at least 10% cover in the 10 years monitored after the fire. The percent cover decline was greater on the high-severity burns than on the low-severity burns . Postfire density of bigleaf aster was recorded the 1st growing season after a spring (low-severity) and a summer (high-severity) fire in northern Minnesota. Bigleaf aster responded less vigorously after the summer wildfire compared to the spring wildfire, with densities averaging 10 stems/mÂ² and 19 stems/mÂ², respectively . On bracken fern-grasslands in Wisconsin, bigleaf aster decreased after fire. However, the change in the percent frequency from before (23.3%) and after fire (17.7%) was only 5.6% .
Immediate Effect of Fire
POSTFIRE REGENERATION STRATEGY :
Rhizomatous herb, rhizome in soil
Caudex/herbaceous root crown, growing points in soil
Geophyte, growing points deep in soil
Secondary colonizer (on-site or off-site seed sources)
Fire adaptations: Bigleaf aster sprouts from rhizomes and root crowns after top-kill by fire. It also establishes after fire by dispersing seeds onto mineral soil from adjacent unburned areas [17,50].
FIRE REGIMES for boreal forest communities, where bigleaf aster occurs most often, are mixed to high severity with fire return intervals ranging from 35 to 200 years. The northern hardwood forests, where bigleaf aster is also known to occur, historically burned infrequently: fire return intervals often greater than 1,000 years. When these forests do burn, fires tend to be low severity because the fuels are relatively wet .
The following table provides fire return intervals for plant communities and ecosystems where bigleaf aster is important. For further information, see the FEIS review of the dominant species listed below.

Bigleaf aster is ubiquitous throughout all seral stages. On Isle Royale National Park it is the most abundant ground cover species in all age groups of postfire succession. It is present in young and old quaking aspen (Populus tremuloides) stands in northwestern Ontario [53,119]. Bigleaf aster was persistent throughout all stages of succession on boreal forests of southern Quebec . These examples suggest that bigleaf aster does not follow a successional trend.
The underground organs of bigleaf aster can aid in the early phases of site recovery after harvesting and fire. The dense, clonal structure of bigleaf aster was an important storage sink for nutrients after whole-tree harvesting on red maple (Acer rubrum) and northern red oak (Quercus rubra) dominated forests of the Upper Michigan Peninsula . On quaking aspen communities of Minnesota and Wisconsin and boreal forests of northern Ontario, the presence of bigleaf aster in the 1st year following fire suggests that it can be a pioneer species [56,92]. Bigleaf aster was abundant in the early postfire (26- and 46-year-old stands) successional stage of boreal forests in southern Quebec . It was a pioneer species during the herbaceous stage of succession on "highland hardwood" burned areas in northern Minnesota . Bigleaf aster is considered a dominant, "competitive" species of early successional boreal forests of Ontario [11,95].
Bigleaf aster is moderately to very shade tolerant [47,94]. The shade tolerance of bigleaf aster allows it to dominate the understory in mid- and late-seral stages [30,94]. After canopy closure bigleaf aster can proliferate for many years by vegetative growth in the understory and by utilizing canopy gaps . Understory vegetation surveys of mid- to late-seral northern hardwood and boreal forests of northern Minnesota, Wisconsin, Michigan, and southern Quebec reveal the presence and often abundance of bigleaf aster [6,26,37,88,101,108,110].
Pollination: Plants in the genus Eurybia are insect pollinated .
Seed production: Buse and Bell  state that bigleaf aster produces large seed crops annually. Bigleaf aster thrives in high light, requiring a moderate amount of light for flowering and subsequent seed production [23,43]. It is frequently found in the vegetative state in densely shaded areas, and the flowering stems are typically not present [43,57,58]. Seed production in these habitats is probably not dependable unless disturbance opens the canopy, allowing increased light.
Seed banking is poorly documented for this species. Ahlgren  stated that there were no bigleaf aster seeds found in soil taken from burned and unburned sites in Minnesota.
Germination: No information is available on this topic.
Seedling establishment/growth: A greenhouse study was done on intact soil blocks taken from an unburned site and adjacent burned site, 3 years after a spring wildland fire in old-growth red pine (Pinus resinosa) in northeastern Minnesota. Bigleaf aster seedlings did not emerge on the soil taken from the burned site. Ahlgren  attributes this to the numerous bigleaf aster sprouts in the area, which had not recovered sufficiently to produce seed. Bigleaf aster seedlings were found on soil samples taken from the unburned site, possibly from windblown seed of older plants that flowered nearby .

increases dramatically after fire that opens the canopy [2,5,76,104]. The ability of bigleaf
aster to flourish on open-canopy sites with charred soils may be attributed to its ability to effectively
control stomatal conductance in open canopy situations (see Physiology).

The literature reviewed below indicates positive and negative aspects of bigleaf aster
to considered when deciding how to manage bigleaf aster populations.
Bigleaf aster responds favorably to other disturbances besides fire. Logging,
windthrow, and road construction have all had positive effects on bigleaf aster
populations [27,45,68,78,79,96,112]. When light, nutrients, and mineral soil become more
abundant, as is the case following tree canopy removal, bigleaf aster enters a
phase of "release" growth, increasing rapidly by vegetative
reproduction and seeds [16,17]. Powell and Brooks  report, however, that
bigleaf aster exhibited "significantly greater cover" (p<0.01) in the remaining standing forest
than in the disturbed areas 2 years after tornado blowdown on a mixed conifer/northern hardwood
forest in northern Minnesota.
Bigleaf aster is a major competitor for light, water,
nutrients, and rooting space
[17,63,95]. The dense, mat-like underground
roots and rhizomes often exclude other species including conifer germinants
[17,39,63]. Bigleaf aster may be allelopathic for some plant species [17,29]. The leachates of bigleaf aster
foliage inhibited germination and early growth of white and black spruce . In laboratory
studies bigleaf aster reduced height growth, dry weight of roots and shoots, and the formation of
secondary needles of red pine seedlings. It also reduced radicle elongation and
slightly hindered the germination of red pine seeds . Allelopathic agents of
the Eurybia genus negatively affect black cherry and sugar maple .
Bigleaf aster is an alternate host of jack pine needle rust (Coleosporeum
asterum) . Its development may be slowed by jack pine needle rust infection,
reducing bigleaf aster cover [11,95].
Hexazinone can reduce bigleaf aster populations. When applied in June on sites in Ontario, it
controlled bigleaf aster for 2 years. An increase
in bigleaf aster abundance followed applications of glyphosate .

Palatability/nutritional value: No information is available on this topic.
Cover value: Bigleaf aster may be an important habitat component for ruffed grouse. It is an important ground cover species in upland forest types of northern Minnesota, where ruffed grouse are common .
Eurybia macrophylla, commonly known as the Bigleaf Aster, Largeleaf Aster or Largeleaf or Bigleaf Wood Aster, is an herbaceous perennial in the composite family that was formerly treated in the genus Aster. It is native to eastern North America where it stretches from the south of the boreal forests of Canada through the northeastern deciduous and mixed forests of New England and south along the Blue Ridge Mountain through the United States. The flowers appear in the late summer to early fall and show ray florets that are usually either a deep lavender or violet, but sometimes white, and disc florets that are cream-coloured or light yellow, becoming purple as they mature. It is one of the parent species of the hybrid Eurybia × herveyi.
Distribution and habitat
E. macrophylla is native to the eastern United States and Canada. In the latter country it can be found in Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island. In the United States it can be found in all states east of and including Minnesota, Iowa, Illinois, Missouri and Tennessee, but excluding states south of North Carolina. It may also be present in Mississippi. The plant has also been introduced outside of its native range into northern Europe. It is most often encountered at 0 to 1300 metre elevations in moist to dry soils in association with hemlock-northern hardwood, beech-maple or pine forests, Appalachian spruce-fir forests, as well as with aspen, pine or open spruce woodlands. It can also be found in thickets, clearings or along shaded roadsides.
The Iroquois use the root as a blood medicine, and they also use a compound decoction of the roots to loosen the bowels to treat venereal disease. The Ojibwa bathe their heads with an infusion of this plant to treat headaches. They also smoke it as hunting charm to attract deer. They also consume the young leaves of the plant as both food and medicine, and they also use the roots to make soup.
