User:Ascaphus

Ascaphus is the genus of primitive frogs that inhabit the mountain streams of northwestern North America. However these frogs are not limited to streams but seasonally migrate upslope into the adjacent conifer forest, and so the habitat of these frogs is forested watersheds, not just streams. The streams do need to have interstitial spaces under rocks. If silt fills the interstitial spaces then the frogs and tadpoles have no cover and cannot survive. The width of a riparian reserve should be what is needed to protect the stream from mud released by logging and related ground-disturbing activities, but ideally entire watersheds should be reserved - and protected from logging and road construction.
