Eunotia subarcuatoides - Alles, Nörpel & Lange-Bertalot

This diatom occurs in high elevation springs and streams in the park. These sites typically have pH levels below 7. Highest abundances of this diatom have been observed in high elevation springs with pH levels between 5.0 and 6.0.



We have records from the springs at Siler’s Bald Shelter, Mount Collins Shelter, Spence Field Shelter, Russel Field Shelter, and springs on both sides of Double Spring Gap, and from Beech Flats Prong and a small un-named stream along the Appalachian Trail.
