Substrate is boulder cobble gravelSIZE 1, HIGH GRADIENT, ACIDIC BEDROCKPlants: acid tolerant bryophytes, non vegetated areasMacroinverts: acid tolerant leaf shredders, low species diversity: Caddisflies (Parapsyche,Palegapetus)-Stoneflies (Capniidae)-Non-biting midges (Eukiefferella), Mayflies(Eurylophella).Other preferential taxa Caddisflies?(Symphitpsyche), Stoneflies (Leuctridae,Taenionema, Chloroperlidae, Peltoperla), Water strider (pools).
