Shasta salamander

Conservation efforts are crucial, given the species' vulnerability due to habitat fragmentation and potential threats such as commercial limestone extraction.

[2][6] Recent studies have expanded its known range to non-limestone habitats, including coniferous forests and mixed woodlands with metasedimentary or metavolcanic rock outcrops.

It thrives in areas with limestone fissures and caves, which also contribute to its reproductive success, as females lay eggs in damp cavern environments.

[8] Factors such as climate change, habitat degradation, and pollution further exacerbate these threats, potentially leading to a decline in population numbers.

Conservation organizations advocate for monitoring and protecting these habitats to ensure the survival of all three species.
