Growing Regions

Black oak is widely distributed throughout the eastern and central United States and extreme southwestern Ontario, Canada.  In the United States, black oak occurs from southwestern Maine west to southern Wisconsin and southeastern Minnesota; south through Iowa to eastern Nebraska, eastern Kansas, central Oklahoma, and eastern Texas; and east to northwestern Florida and Georgia [56].

     

General Information

The currently accepted scientific name of black oak is Quercus velutina Lam. [36]. It has been placed within the subgenus Erythrobalanus, or red (black) oak group [51,56]. The following rarely used forms have been distinguished on the basis of leaf lobe variation and pubescence [61]: Q. v. f. macrophylla (Dippel) Trel. Q. v. f. dilanianta Trel. Q. v. f. pagodaeformis Trel. There appears to be complete integration between the forms [61]. Some northern populations of black oak in the Lower Peninsula of Michigan have smaller acorns with less cup cover, lighter inner bark, smaller winter buds, and a more branching growth form than populations in southern Indiana [56]. Voss [64] suggests that these may be hybrids between black oak and northern red oak (Q. rubra) or scarlet oak (Q. coccinea). Black oak hybridizes with the following species [36,56]: x Q. coccinea (scarlet oak): Q. X fontana Laughlin x Q. ellipsoidalis (northern pin oak): Q. X palaeolithicola Trel. x Q. falcata (southern red oak): Q. X willdenowiana (Dippel) Zabel Q. X pinetorum Moldenke x Q. ilicifolia (bear oak): Q. X rehderi Trel. x Q. imbricaria (shingle oak): Q. X leana Nutt. x Q. incana (bluejack oak): Q. X podophylla Trel. x Q. marilandica (blackjack oak): Q. X bushii Sarg. x Q. nigra (water oak): Q. X demarei Ashe x Q. palustris (pin oak): Q. X vaga Palmer & Steyerm. x Q. phellos (willow oak): Q. X filialis Little x Q. rubra (northern red oak): Q. X hawkinsiae Sudw. x Q. shumardii (Shumard oak): Q. X discreta Laughlin

Black oak is a common component of many eastern and central upland
deciduous forests.  Black oak also occurs in savannas in the transition
zone between the eastern deciduous forests and the western prairies.

The following published classifications list black oak as a dominant or
codominant species:
