Habitat:
This species inhabits mountain streams and rivers in coastal woodlands and redwood forest. When inactive, individuals are found under rocks, logs, other forest debris, and in rodent burrows and subterranean crevices. Adults move from terrestrial habitats to nearby streams and rivers for breeding, wherein eggs are laid on the undersides of rocks. Only areas with flowing water are used, as this species does not appear to utilize ponds or other standing water habitats (Green et al. 2014). Breeding is by larval development.
Range:
This species occurs in coastal California, from the Estero Americano north to the Eel River in the western versant of the Coast Range. It is found at elevations between 150–450 m asl (Green et al. 2014). A new subpopulation of Taricha rivularis was discovered in the Santa Cruz Mountains of Santa Clara County, which is located approximately 130 km south of the closest known locality in Sonoma County, California. The origin of this subpopulation is unknown. It is thought that it may have been introduced, however this seems relatively unlikely due to the remote nature of the location and lack of previous surveys to the area (Reilly et al. 2014). The extent of occurrence (EOO) for this species is 19,584 km2. It likely occurs in ten or fewer threat-defined locations due to intensive conversion of suitable habitat to agriculture across its range.
Conservation:
Conservation Actions In-Place
This species occurs in a number of protected areas, however a large portion of its range occurs on private lands. It is considered a species of Special Concern in California.
In an effort to prevent the introduction of Bsal into the US, an Interim Rule of the Lacey Act has been enacted that bans the importation of 201 species of salamanders (USFWS 2016). Additionally, a temporary voluntary trade moratorium of imports of Asian salamander species that are known to carry the disease until such time as effective testing and treatment regimens can be developed and distributed has been recommended to all exporters, shippers, sellers and buyers by the Pet Industry Joint Advisory Council (PIJAC). A North America Bsal Task Force has also been created, with working groups designed to address a variety of disease prevention and mitigation goals (North America Bsal Task Force 2021).
Conservation Needed
Continued and strengthened management of protected area(s) where this species occurs, and expanded protection of suitable habitat elsewhere in its range is needed.
Research Needed
More information is needed on this species' distribution, population status, ecology, and threats. As much of this species' range occurs on private lands it can be difficult to study, however surveys are greatly needed to better understand the current status of this species (S. Marks pers. comm. August 2020).
