Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 6 - 80
Comments: The precise number of distinct occurrences is unknown, however, as of March 2007 there are 56 accession records in the Consortium of California Herbaria database; 29 of these have been collected since 1980.
Life History and Behavior
National NatureServe Conservation Status
Rounded National Status Rank: NNR - Unranked
NatureServe Conservation Status
Rounded Global Status Rank: G3 - Vulnerable
Reasons: Allium cratericola is restricted to California and, although it occurs across a large area, it has a somewhat restricted elevation range and soil preference. There is no element occurrence data available, however, it is uncommon according to Hickman (1993) and does not have a large number of collections in California herbaria.
