Chilly Winter Greetings TN Dragonfliers, A look at Odonata Central records for Tennessee as of January 15, 2014. For 2013 for the 95 TN counties, the average number of odes recorded per county is at 35.4 species per county, up from 34.5 the previous year (2012). Of course it takes 95 records to raise the average one full point, so we submitted only slightly less than that. Basement counties are 19 at 19 or less, that is, there are 19 counties with fewer than 20 recorded species. And there are now just 6 counties in single digits. Or to look at it another way, we still have 6 counties in single digits! But we have not been at this very long, and if our ranks are few then slow progress is to be expected. By comparison the average number for Butterflies is now over 50 per county! The leading county is still Blount at 86, others close are Sullivan (75), Cumberland (74) & Davidson (71). More thoughts on Blount Co. in another post. Just in case you are interested in this format, I have attached TN counties lists, amended from last winter's lists, one in alphabetical order and another from least to most. There may be those among us with better math and computer skills to deal with the numbers and statistics and distribution, and I'd welcome any other perspectives. I miss David Trently's Species Not-Seen page from a few years ago. Looking forward to warmer weather and flying odes to chase. Richard Connors Nashville
