Rank Reasons
Leucocrinum montanum is a widespread perennial herb occurring in sandy and rocky areas in scrub flats, short-grass prairies, sagebrush, and open montane forests of western and central North America from Oregon east to North Dakota, south to New Mexico, and west to California, United States. There are over 1,800 occurrences of this species, which are potentially threatened by development, right of way maintenance, and invasive species. However, with a large range extent, high number of occurrences, and broad habitat preferences for abundant habitat, Leucocrinum montanum is considered secure.
Range Extent Comments
Leucocrinum montanum occurs in western and central North America from Oregon east to North Dakota, south to New Mexico, and west to California in the United States (FNA 2002). Range extent was estimated to be 1.7 million square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens and photo-based observations documented between 1993 and 2024, it is estimated that there are over 1,800 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Leucocrinum montanum is potentially threatened by development, rights-of-way maintenance, invasive species, and other threats in some places. However, they are considered negligible given the broad range and large number of occurrences of the species and its somewhat flexible and abundant habitat, as well as no obvious intrinsic vulnerabilities.
