I have tried to get every species added so far, but please send me a message if you have a species observation that is more than a couple days old that needs to be added to the iNat database.

Keep up the good work!

Please note that student observations in this project are reviewed by TRAINED DIATOM EXPERTS AND INSTRUCTORS OF THE COURSE. If you do not have expert knowledge of diatoms, please refrain from demoting the observation to broader classification groups. Please do not undo the hard work of students making species level identifications. Thank you for your cooperation!
