Disclaimer: Maps shown on this Web site were created initially by manually coding maps in the original publications and creating new maps from those data. The new maps were checked for errors, but there is a possibility that some errors remain. Current maps may also reflect new county records that have been established since the date of publication. Users of this Web site need to understand that data are more complete for some species and counties than others. Absence of a county record for a particular species may mean that 1) the species does not occur there, 2) the species is present but has not been detected and reported yet, or 3) a county record exists but has not yet been added to our database.
