Abundance response to fire: Survival and sprouting: Most often found on stoney slopes in chaparral in Southern CA and in Baja CA. When mature, this form produces a single unbranched flower stalk, and the entire plant dies after flowering [15,22,31,83]. This fire behavior supported irregular fire intensities that changed with fuel and weather conditions and created patchiness in stand structure. They typically split in mid-August, and seeds are dispersed in gusty winds [18]. It makes flowers like a yucca (and is also pollinated by a yucca moth, Tegeticula maculata) but dies after flowering, like an agave. At San Diego State University's Oaks Biological Field Station, the average density of chaparral yucca seedlings was 0.4/m² in the first postfire growing season after a January prescribed fire on south-facing slopes dominated by 57-year-old chaparral vegetation. for additional information on the prevailing fire regimes in vegetation where chaparral yucca and Newberry's yucca may occur.

Maximum fruit set of 29.1% was recorded for a plant outside the study area. After 3 years of storage at 40 °F (4 °C), 75 % of seeds germinated . Analyses of sediment cores from the Santa Barbara Channel in southern California suggest that large fires occurred every 40 to 60 years in the 1700s and 1800s (Byrne and others 1977 cited in [66]). Monocarpic forms produced the largest capsules with the most seeds, but when mature fruits from all growth forms were combined, the number of seeds/locule was positively correlated with elevation, distance from the coast, and total annual precipitation (P<0.05). The leaves are as show stopping as the flowers; the leaves are grey-green swords to three feet long, fairly quickly growing into a hemisphere of needle-tipped sawtooth-edged glorious beauty. Shrublands: The number of capsules free of larvae was substantially greater for monocarpic than caespitose or rhizomatous forms [61]. In turn, the moth pollinates the yucca and disperses its seeds, facilitating yucca growth in the region. Evaporation was least in February and March and greatest in July and August [76]. *A 2nd Hesperoyucca species commonly known as Newberry's yucca (H. newberryi (McKelvey) Clary) [23,54,108] is also recognized.
