Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 1 seed accessions of Dudleya stolonifera from 1 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass an unknown number of maternal plants
Known only from 6 populations, all located near Laguna Beach, California. There are estimated to be 8,000-10,000 individuals in total. Although the species' habitat is relatively inaccessible, adjacent urbanization has accelerated the invasion of non-native plants. Horticultural collection is also a threat.
