The Populus Grandidentata is commonly known as the Aspen, Bigtooth Aspen as well as Largetooth Aspen.

The currently accepted scientific name for bigtooth aspen is Populus grandidentata Michx. (Salicaceae) . Bigtooth aspen, along with five other aspen species, has been assigned to the subsection Trepidae of the section Leuce in the genus Populus. Because of their similarities, these six species are sometimes considered a single super species . Bigtooth aspen and quaking aspen (P. tremuloides) are the only two North American aspen species. In literature concerning areas where both North American aspen species occur, many authors do not distinguish between bigtooth aspen and quaking aspen. The information is reported about "aspen" in general. In this writeup, "aspen" is used when citing studies in which both species are discussed collectively. Bigtooth aspen naturally hybridizes with the following species : x P. tremuloides: P. xsmithii Boivin x P. alba (white poplar): P. xrouleauiana Boivin

Bigtooth aspen primarily occurs in the northeastern United States, southeastern Canada, and the Great Lakes Region. Its range extends from 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 .

Bigtooth aspen usually grows in even-aged mixed stands, most commonly with quaking aspen . It is a codominant tree in both hardwood and conifer forests . Bigtooth aspen does not occur as a subdominant species because of its extreme shade intolerance . 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 . Aspen stands dominated by bigtooth aspen are generally more open than those dominated by quaking aspen . 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) . A tall shrub layer is an important component of aspen forests . 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) . Bracken fern (Pteridium aquilinum) and dwarf bush-honeysuckle (Diervilla lonicera) are frequent subdominant understory species in bigtooth aspen stands . 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 2. Aspen association in northern lower Michigan
