Rank Reasons
Ohio buckeye (Aesculus glabra) occurs in eastern North America, from southern Ontario and western Pennsylvania, to southeastern Nebraska, south to central Texas, Arkansas and Alabama. There are likely more than 1500 occurrences. Threats include the fragmentation and loss of habitat due to residential development, and competition from invasive exotic species.
Range Extent Comments
Ohio buckeye (Aesculus glabra) occurs in eastern North America, from southern Ontario and western Pennsylvania, to southeastern Nebraska, south to central Texas, Arkansas and Alabama. Range extent was estimated to be 1.8 million square kilometers, using herbarium specimens and photo-based observations documented between 1992 and 2023 (Burns and Honkala 1990, GBIF 2023, iNaturalist 2023, Weakley and Southeastern Flora Team 2022).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1992 and 2023, it is estimated that there are more than 1500 occurrences rangewide (GBIF 2023, iNaturalist 2023).
Threat Impact Comments
Threats include the fragmentation and loss of habitat due to residential development and competition from invasive exotic species.
Ecology & Habitat

Habitat

Ohio Buckeye occurs in mesic upland and riparian forests, mostly on mesophytic sites, also on bluffs, in ravines, and along stream banks, usually over calcareous substrates (Burns and Honkala 1990, Weakley and Southeastern Flora Team 2022).

Ecology

Is not a pioneer species, and is seldom found in old fields (Burns and Honkala 1990).
