DISTRIBUTION AND OCCURRENCE
SPECIES: Celtis occidentalis | Hackberry 



GENERAL DISTRIBUTION : 
Hackberry is widely distributed in the eastern United States from
northwest Minnesota to central Wisconsin and Michigan into central New
York and throughout the southern New England states.  It is found as far
south as northern Georgia, Alabama, northeastern Mississippi and central
Arkansas.  This species' range extends west through central Oklahoma,
and includes most of Kansas, Nebraska, South Dakota and eastern North
Dakota [21].  Hackberry also grows along the Arikaree river in eastern
Colorado [4].  In Canada hackberry is local in the extreme southern
reaches of Manitoba, Quebec and Ontario [17].  The exact southern part
of its range is difficult to establish because of hackberry's similarity
to sugarberry (C. laevigata) [21].
