Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 7 accessions of Acmispon argophyllus var. adsurgens in orthodox seed collection. There are as many as 8458 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 3 seed accessions of Acmispon argophyllus var. adsurgens from 2 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass an unknown number of maternal plants

The introduction of alien herbivores more than a century ago has had dramatic negative effects on plant community composition on all of the Channel Islands. These effects include the reduction of native plant cover, density and biomass. Intensive herbivor
Lotus argophyllus var. adsurgens is known from 10 populations at the southern tip of San Clemente Island. (USFWS 1996)
Liston and colleagues (1990) found a low degree of hybridization between Lotus species on San Clemente Island. Although hybridization was not extensive, it may still pose a long-term threat (Liston et al. 1990).
Since the U.S. Navy has removed goats, as a part of its Feral Animal Removal Program, the general condition of native species has improved (CDFG 2002).
Population monitoring and continued habitat restoration as well as understanding reproductive ecology and habitat needs through various life stages will all aid in conservation efforts.
