Shasta salamander
species of amphibian
The Shasta salamander (Hydromantes shastae) is a species of salamander in the family Plethodontidae. It is endemic to Shasta County in California.
Taxonomy
Formerly considered to be a single species with a rather small distribution in the vicinity of Shasta Lake, a 2018 study found it to comprise three species, including H. shastae sensu stricto, and two new species: the Samwel Shasta salamander (H. samweli), found in the north-central and northwest sides of the lake, and the Wintu Shasta salamander (H. wintu) on the northern shore of the lake near the McCloud River. Both species are physically similar to H. shastae and can only be distinguished by range and genetics. The reclassification of the Shasta salamander complex into three distinct species highlights its ecological significance, as each species occupies different, highly specific habitats. Conservation efforts are crucial, given the species' vulnerability due to habitat fragmentation and potential threats such as commercial limestone extraction.
Distribution and habitat
It is found in the Cascade Range in areas around Shasta Lake with limestone substrate, primarily between Squaw Creek and the Pit River, but also on the south side of Shasta Lake and in the vicinity of Ingot. Recent studies have expanded its known range to non-limestone habitats, including coniferous forests and mixed woodlands with metasedimentary or metavolcanic rock outcrops. Its natural habitats are temperate forests, freshwater springs, rocky areas, and caves. The Shasta salamander's habitat provides essential moisture and protection from temperature extremes.

Why this record matters
“Shasta salamander” is worth following because a concise public description often conceals a longer documentary argument. Here, Shasta, salamander and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q308216. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
