Rank ReasonsInch-high Lupine (Lupinus uncialis) occurs in the western United States, in the Great Basin of northern and central Nevada, southeastern Oregon, southwestern Idaho, and Modoc County in eastern California. There are between 81 and 300 occurrences rangewide, it is fairly common in northern Nevada and is rare in the other states where it occurs. It is most common in years of heavy rainfall, so it is threatened by extreme or long-term drought, such as may be exacerbated by climate change. In portions of the Intermountain West, the invasive exotic plant, cheatgrass (Bromus tectorum) has replaced native annuals such as Inch-high Lupine.
Range Extent CommentsInch-high Lupine (Lupinus uncialis) occurs in the western United States, in the Great Basin of northern and central Nevada, southeastern Oregon, southwestern Idaho, and Modoc County in eastern California. Range extent was estimated to be 170,000 square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1982 and 2023 (CNDDB 2023, GBIF 2023, iNaturalist 2023, Kartesz 1988, NatureServe 2023, SEINet 2023).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records, 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 (CNDDB 2023, GBIF 2023, iNaturalist 2023, NatureServe 2023, SEINet 2023).
Threat Impact CommentsInch-high Lupine (Lupinus uncialis) is most common in years of heavy rainfall (Kartesz 1988), so it is threatened by extreme or long-term drought, such as may be exacerbated by climate change. In portions of the Intermountain West, the invasive exotic plant, cheatgrass (Bromus tectorum) has replaced native annuals such as Inch-high Lupine (Lupinus uncialis), exotic annual grasses compete directly with these native plants for space, moisture, and light, and indirect impacts caused by exotic annual grasses include increased fire frequency and the associated conversion of shrub-steppe to nonshrub annual grasslands (Rosentreter 1994).
