The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Oncorhynchus clarkii seleniris (Snyder, 1933)

Common name: Paiute cutthroat trout

Synonyms and Other Names: Salmo clarkii seleniris. Species epithet commonly misspelled as 'clarki'.

Taxonomy: available through www.itis.govITIS logo

Identification: Similar in color to other forms of Cutthroat Trout, especially Lahontan Cutthroat Trout, but can be distinguished by an overall green, bronze, to yellow body coloration, a nearly total lack of black spots on the body, and the retention of parr marks in adults (Moyle 2002; Moyle et al. 2008).

Native Range: Approximately 15 km of Silver King Creek and its tributaries (Tamarack Creek, Tamarack Lake Creek, and lower reaches of Coyote Valley Creek) below Llewellyn Falls and upstream of Silver King Canyon Gorge, Humboldt-Toiyabe National Forest, Alpine County California (Moyle 2002; USFWS 2004).

Nonindigenous Occurrences: This species has been stocked in several alpine lakes and streams in California. The first documented introduction of Paiute Cutthroat Trout was to Leland Lakes in 1937 (Cordes et al. 2004; USFWS 2004; Moyle et al. 2008). In 1946, 401 fish from Bull Canyon, Corral Valley, and Coyote Valley Creeks were stocked into several spots along one mile in the upper portion of the North Fork of Cottonwood Creek, Inyo National Forest, Mono County (Vestal 1947; USFWS 2004).

Additionally, it is thought that there have been several undocumented or unreported introductions. Paiute Cutthroat Trout likely were introduced into Silver King Creek above Llewellyn Falls in 1912 (Connell, in Ryan and Nicola 1974). The populations in both Corral Valley and Coyote Valley Creeks (tributaries to Silver King Creek) were likely stocked by loggers or farmers at some point in the 1860-1880s: it is assumed that small falls near the mouth of Corral Valley creek were a historic barrier to entry for fishes, and these streams both contained Paiute Cutthroat Trout by 1889 (USFWS 2004).

Means of Introduction: Stocked. Cottonwood Creek was stocked for conservation purposes due to the decline of the Silver King Creek basin population (Vestal 1947)

Status: Established in California (Moyle 2002; USFWS 2004)

Remarks: Originally listed as 'endangered' under the Endangered Species Act in 1966; later reclassified (and currently remains) as 'threatened' in 1975 (USFWS 2004). Although the population of Paiute Cutthroat Trout in Coyote Valley and Corral Valley Creeks above the barrier falls are thought to have been introduced at some point in the late 1800s, no records of the fauna in these creeks exist prior to 1889 and it is possible that these populations are in fact native (USFWS 2004; Moyle et al. 2008).
