Rank Reasons
Townsendia scapigera is a wide ranging short-lived perennial or biennial herb occurring in the western United States with most occurrences in Nevada but it is also found in California, Oregon, Idaho, and Utah at the periphery of its range. There are between 100 and 200 known occurrences over a large range but little is known about threats or trends.
Range Extent Comments
Townsendia scapigera occurs in the western United States, where it is found throughout much of Nevada (Kartesz 1988) and eastern California, largely east of the Sierra Nevada but other occurrences reported from the Modoc Plateau and Warner Mountains (Jepson Flora Project 2023). It also occurs in western Utah (Box Elder and Millard Counties) (Welsh 1993), southern Idaho (Twin Falls County) (Idaho Department of Fish and Game 2023), and southeastern Oregon (Malheur County) at the periphery of its range (FNA 2006c). Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1992 and 2023 (GBIF 2023, iNaturalist 2023, NatureServe 2023, SEINet 2023).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1982 and 2023, it is estimated that there are between 81 and 300 occurrences rangewide (GBIF 2023, iNaturalist 2023, NatureServe 2023, SEINet 2023). There are nearly 100 occurrences in Nevada and 50 in California. Elsewhere the species is rare, with only a few occurrences likely extant.
Ecology & Habitat

Habitat

This species is found in alpine tundra, rocky slopes, and openings in sagebrush at elevations ranging from 1,400 to 3,400 meters (FNA 2006c, Welsh et al. 2015, Jepson Flora Project 2023).
