Species range
Mountain brush, aspen, spruce-fir, and alpine meadow communities at ca 1890 to 3050 m in Salt Lake, Utah, Wasatch, and Weber cos. (Welsh et al. 2015). Occurring in riparian areas: gravel bars and edges of streams.
Estimate from download of data from Utah Rare Plant Database on October 20th 2022.
Geocat 50 observations: Extent of Occurrence: 1,572.855 km2.
*Two historic herbarium collections were not used (A.C.Blauer 7/16/1964 Along stream bank in Bear canyon Lat 41.98849, Lon -111.68499 and F.M. Ownbey 7/19/1946 About 1 mile above Alta, Little Cottonwood Canyon, Wasatch Mountains 40.60329, -111.638). The Ownbey record is likely represented within the EO poly near Alta in Little Cottonwood Canyon, but should be revisited. The Blauer observation warrants further investigation as it would greatly extend the distribution of this species towards the Utah-Idaho border. All other historic observations were retained in ranking dataset if more recent observations are within 1 km.
Threats or limiting factors
The largest threat to this species is likely due to habitat loss attributed to climate change and to a lesser extent construction projects including a recently (2021) proposed roadway expansion and stream reconstruction at Thousand Springs in Mill Creek Canyon Utah (P21FRA01UTUS). The Utah Division of Water Resources confirmed the Utah is now in "extreme" or "exceptional" drought. Droughts and rapid snowmelt due to wind-blown sediments are melting snowpack earlier than normal in our region.
