Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 1 accessions of Astragalus lentiginosus var. micans in orthodox seed collection. There are as many as 9317 seeds of this species in their collection - although some may have been used for curation testing or sent to back up.
Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 1 seed accessions of Astragalus lentiginosus var. micans from 1 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass an unknown number of maternal plants
Species is widespread, var. is very rare. There are only two known populations for this variety in the Eureka Dunes area in California. One is remote, but the other suffers from too many visitors who like to hike, ski, sled, drive and camp on the dunes, thereby crushing the plants. The BLM has limited staff to patrol and control the public, so these threats continue to affect the known populations.
Potential threats include:
Illegal off-road vehicle use
Competition with alien plants (Russian thistle)
There are only two populations left: Eureka Dunes and the Saline Sand Spur (USFWS 1998).
There have been studies by the National Park Service over the past few decades that show that this species can recolonize areas once the source of the disturbance has been removed as long as the seed bank remains. (USFWS 1998)
Pavlik and Barbour (1988) published a demographic monitoring paper for this and other species in the Eureka dunes habitat.
This species co-occurs with other federally endangered species, and this association serves as an umbrella of protection over this species and the habitat it requires.
Continue to monitor both known populations.
