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) [114]. 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 [89].

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 [15].
The following table provides fire return intervals for plant communities and ecosystems where bigleaf aster is important. Find fire regime information for the plant communities in which this species may occur by entering the species name in the FEIS home page under "Find FIRE REGIMES".

Bigleaf aster may aid in preventing wildfire ignition and slowing fire spread. Hogenbirk and Sarrazin-Delay [
51] 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.

Management considerations

More info for the terms:
cover,
forest,
formation,
hardwood,
phase,
radicle,
treeThe literature reviewed below indicates positive and negative aspects of bigleaf aster
to considered when deciding how to manage bigleaf aster populations.
Disturbance:
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 [81] 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.
Interference:
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 [36]. 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 [74]. Allelopathic agents of
the Eurybia genus negatively affect black cherry and sugar maple [36].
Disease:
Bigleaf aster is an alternate host of jack pine needle rust (Coleosporeum
asterum) [8]. Its development may be slowed by jack pine needle rust infection,
reducing bigleaf aster cover [11,95].
Control: 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 [
17].

wildfireBigleaf 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 [96] 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 [96]. Research reveals, however, that bigleaf aster is capable of vegetative regrowth after low- and high-severity fires.
Smith [100] 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 [45]. 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 [66]. 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/m² and 19 stems/m², respectively [77]. 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% [111].
Bigleaf aster also persists after fire by dispersing seeds onto mineral soil from adjacent undisturbed areas [17,50].

wildland fireBigleaf aster regenerates by seed and vegetative means. Regeneration is largely by vegetative means from rhizomes and root crown sprouts [2,17,78,118].
Pollination: Plants in the genus Eurybia are insect pollinated [13].
Breeding system: Plants in the genus Eurybia are gynomonoecious and dichogamous [13]. Natural hybridization is common in the genus Eurybia [87].
The annual clonal expansion of bigleaf aster can be up to a horizontal distance equivalent to the mother plant's height [69,98].
Seed production: Buse and Bell [17] 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 dispersal: Seeds of bigleaf aster are widely dispersed by small mammals and wind [2,17,50,98].
Seed banking is poorly documented for this species. Ahlgren [7] 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 [7] 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 [7].
Asexual regeneration: Bigleaf aster reproduces by rhizomes or by sprouting from the root crown [17,78,118].

successionBigleaf 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 [31]. 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 [27]. 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 [31]. It was a pioneer species during the herbaceous stage of succession on "highland hardwood" burned areas in northern Minnesota [44]. 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 [30]. 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].

Eurybia macrophylla: Brief Summary
provided by wikipedia EN
Eurybia macrophylla, commonly known as the bigleaf aster, large-leaved aster, largeleaf aster or bigleaf wood aster, is an herbaceous perennial in the family Asteraceae that was formerly treated in the genus Aster. It is native to eastern North America, with a range extending from eastern and central Canada (from Nova Scotia to Manitoba) through the northeastern deciduous and mixed forests of New England and the Great Lakes region and south along the Appalachians as far as the northeastern corner of Georgia, and west as far as Minnesota, Missouri and Arkansas. 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.
