Definitions of codes preceding a county and/or quad:
*		Presumed extirpated
?		Uncertain about distribution or identity
?*		Uncertain about distribution, but presumed extirpated if once present
(?)		Occurrence confirmed, but possibly extirpated

Species may be present in other areas where conditions are favorable.
