Dudleya stolonifera is known to be in cultivation, and is threatened by overcollection. Field-collected specimens of D. stolonifera have been found in southern California nurseries and are likely to be harvested for private collections. This species occurs within an area that is experiencing rapid urbanization. The species has been collected historically and is apparently still at risk from unauthorized collection. Members of this genus are particularly prized by collectors and, while little is known considering actual trade, there is a high potential for trade impacts.
Populations are small and easily accessible.
Approximately 8,000 to 10,000 individuals of Dudleya stolonifera are spread among 6 locations. Urban development and associated edge effects threaten several populations of D. stolonifera . Herbivory may threaten some populations of D. stolonifera as well. Land acquisition and management by State or local agencies or by private groups and organizations have contributed to the protection of some localities containing the Dudleya stolonifera.
