Hi. Thank you for all this great info. Forgive me if I am missing it, but do you know the total number of RG Observations for 2022 and the total number of Observers? Thanks. -Marty

Thank you very much. I added those to a chart I keep (for presentations). The original survey years were supposed to be 2017-19, right? Is there an end in sight with this current extension or is it open ended? Thank you.

Hi Marty, the "official" Ohio Dragonfly Survey was for the three year period 2017-19. We have been able to continue the project given the on-going interest of contributors and curators. As long as the observations come in and I'm willing to integrate the iNat data with the Ohio Odonata Society database, it's open-ended.
