The range of shortleaf pine extends north into New Jersey and Pennsylvania (maybe further north), and west into Texas and Oklahoma.  It has some oddities in the BONAP maps that suggest that it has been poorly documented with herbarium specimens in Georgia.  Based on what we know from BONAP and ISB, the range in north Florida is likely continuous, but likely  does not extend down to the Gulf Coast.  Given land uses, it may once of been more frequent and included counties from which there are no herbarium specimens.  This pine has been used commercially for timber production, especially north of Florida.  Overall, it appears appropriate to plant this species in appropriate soil conditions anywhere in the Florida panhandle and east to Columbia County.
