Rank Reasons
Eriogonum ostlundii is a herbaceous perennial buckwheat that is endemic to three counties in central Utah. It is relatively common within its limited range but faces some threats from development, mining, and off-road vehicles.
Range Extent Comments
Eriogonum ostlundii is endemic to Piute, Sanpete, and Sevier Counties, Utah, United States (FNA 2005, GBIF 2024). Range extent was estimated to be 1300 square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024). Including observations from 1983 to 1992, the range extent is estimated to be 2000 square kilometers (GBIF 2024, NatureServe 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are 11 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024). Including observations from 1983 to 1992, it is estimated that there are 35 occurrences rangewide (GBIF 2024, NatureServe 2024, SEINet 2024).
Threat Impact Comments
Few threats are documented for occurrences of Eriogonum ostlundii but mining, off-road vehicle tracks, residential and commercial development, and logging are visible in or near occurrences on aerial imagery from 2024.
