Comments: Since Dudleya cymosa ssp. ovatifolia mostly occurs on rocky outcrops with little vegetative cover, it is only slightly threatened at this time by roadside scraping for weed control, fire suppression activities (such as brush clearing), horticultural collection, grazing, nonnative insects (Argentine ants) and plants (USFWS 2009). While in the past populations had been lost to urban (residential and commercial) development, newer development seems to be more accommodating to this taxon, leaving its habitat zoned as open space and promising protection (USFWS 2009). Yet, secondary effects of urbanization, such as recreational activities (like rock climbing and hiking), are becoming a more prominent threat. Since most of the habitat exists on private land, direct and indirect impacts from current and future development is always a threat (USFWS 2009). Climate change is a possible threat, the extent of which is not yet known (USFWS 2009).
