The glory days of the Ozark chinquapin are past. Like the famous American chestnut of the Appalachian Mountains, Ozark chinquapin was decimated by the chestnut blight that was accidentally introduced into North America in the early part of the last century. Today, survivors of the blight hang on as stumps that send up new sprouts periodically, but which never live long enough to gain the stature of a tree.
Distribution & Occurrence
Uplands and cliff margins and ridges, and at the base of talus slopes on limestone, sandstone and chert, or a combination of these. Occurs in dry oak-hickory or oak-pine forests, with white oak, black oak, scarlet oak, and shortleaf pine dominating. Flowering individuals occur in edge habitats. Ironwood strongly associated in Oklahoma (Schnell et al. 1977). Elevation 500-2800 ft.
Conservation, Ecology & Research
Successfully propagated from seed using 3 month cold/moist stratification pretreatment (Nebraska Statewide Arboretum).
Several individual Ozark chinquapin trees are in cultivation in Nebraska, outside of the historic range of this species and, apparently, outside of the natural range of chestnut blight fungus. These trees were propagated by the Nebraska Statewide Arboretum from seed collected from wild populations in the Missouri Ozarks.
