Thanks for the database analysis. More observers in different counties or more different dragons in counties or a combo?
There's a couple things going on.
Some counties have been under-represented. So, for these counties, simply having someone routinely look around has an impact. A single observer can make a difference (jheiser in Coshocton is a prime example - thanks you Jay).
For species, the big gains have been in species where we're seeing a northerly range expansion (Carolina Saddlebags, Slaty Skimmer).
Basically more people looking, and some new bugs.
Another analysis would be where we've failed to verify historical species - for another day.
Sounds good to me...thanks
