      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. This data should NOT be substituted for pre-project review or for on-site surveys.
