I noted this on FHF, and wanted to share it here also.
First let me give you and update. I have been working on the PA Species County List for the past few weeks, and thanks for all those he have submitted there information on species in there counties, a great help. I should probably explain it a little more so you have an idea of the list. I am taking everyones data and comparing it to an older list or two I have come by. The good news is the list is more up-to-date and we have added a few new county records and knocked off a few historic ones as well.
Now I have a utility that keeps track of the list and the data submitted to the PAHERP Database so when a new record that has not been added to that county or is unvouchered for 2000-2009 or historic for the county i can make proper changes to the list.
So sense I have been working on the PA Species County List I have noticed many species that have been listed as historic or not recorded for a county that people have noted in that county. Some as common as a ringneck or n. water snake are historic in one or two counties.
So basically keep a good record and coordinates for whatever you find. Never know if it was historic or a range extension.
Sometimes the small things are important.
