Virginia north to Maine and Cape Breton Island, Nova Scotia; west to
southeastern Manitoba and Minnesota; south through Iowa to extreme
northeastern Missouri; and east through Illinois, Indiana, Ohio, and
West Virginia.  Disjunct populations are found in Kentucky, Tennessee,
North Carolina, and South Carolina [29,30].

HABITAT TYPES AND PLANT COMMUNITIES : 
Bigtooth aspen usually grows in even-aged mixed stands, most commonly
with quaking aspen [29,43].  It is a codominant tree in both hardwood
and conifer forests [13].  Bigtooth aspen does not occur as a subdominant
species because of its extreme shade intolerance [38].

Quaking aspen is the predominant species in aspen stands in the
Northeast and Great Lakes Region, but bigtooth aspen dominates
on the drier upland sites [13,17].  Aspen stands dominated by bigtooth
aspen are generally more open than those dominated by quaking aspen
[17].

Overstory associates not previously mentioned in DISTRIBUTION AND
OCCURRENCE include balsam poplar (Populus balsamifera), bur oak (Quercus
macrocarpa), white oak (Q. alba), basswood (Tilia americana), black
cherry (Prunus serotina), and sassafras (Sassafras albidum) [29].

A tall shrub layer is an important component of aspen forests [35].
Shrub associates include chokecherry (Prunus virginiana), downy
serviceberry (Amelanchier arborea), dogwood (Cornus spp.), willow (Salix
spp.), beaked hazel (Corylus cornuta), speckled alder (Alnus rugosa),
American hazel (Corylus americana), and sweetfern (Comptonia peregrina)
[13,29].

Bracken fern (Pteridium aquilinum) and dwarf bush-honeysuckle (Diervilla
lonicera) are frequent subdominant understory species in bigtooth aspen
stands [17,29,56].

Bigtooth aspen is listed as a dominant or codominant species in the
following publications:

1.  Wilderness Ecology:  virgin plant communities of the Boundary Waters
      Canoe Area [35] 
2.  Aspen association in northern lower Michigan [17]
