Rank Reasons
Glyptopleura marginata is a wide-ranging annual herb in arid grasslands, rocky or sandy deserts, and alkali flats of the Great Basin and Mojave deserts in western United States from southwestern Idaho and southeastern Oregon, Nevada, California, and Utah. There are over 200 occurrences which face threats from development, conversion to agriculture, livestock trampling, recreational activities, and invasive species. Little is known about trends, but with a large range extent and large number of occurrences, and no obvious intrinsic vulnerabilities, this species is considered apparently secure.
Range Extent Comments
Glyptopleura marginata occurs in the Great Basin and Mojave deserts in western United States from southwestern Idaho and southeastern Oregon, Nevada, California, and Utah (FNA 2006). Range extent was estimated to be over 530,000 square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025 (GBIF 2025, iNaturalist 2025, NatureServe 2025, SEINet 2025).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025, it is estimated that there are over 200 occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, SEINet 2025).
Threat Impact Comments
Although threats are not widely documented, this species is potentially threatened by development, conversion to agriculture, livestock trampling, recreational activities (especially off-road vehicles), invasive species (such as cheatgrass (Bromus tectorum)), and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and no obvious intrinsic vulnerabilities.
