Q. dumosa (sl) sprouts from the root crown or burl after fire (for example, [96,103]) or other top-killing events, including browsing [33,139], herbicide application [83,90,174,176,177], and cutting . On chaparral sites across California, Keeley  noted a few Q. dumosa (sl) sprouts that had originated from roots. Heavily browsed California scrub oaks on Santa Cruz Island sprouted from the base after feral domestic sheep were removed in the late 1950s [32,33]. California scrub oak sprouts were noted on clearcut fuelbreaks in San Diego County .
However, California scrub oak and coastal sage scrub oak do not require top-kill to sprout, and adult plants may produce sprouts in all stages of succession . Fites-Kaufman and others  classify Q. dumosa (sl) as a "fire-neutral" species that sprouts continuously, with sprout recruitment after fire similar to sprout recruitment without fire. On old burns (>54 years) in the Santa Ana Mountains, Q. dumosa (sl) replaced old stems with new sprouts continually, so stems dating back to the last fire were relatively rare .
Although Q. dumosa (sl) seedlings and saplings usually grow slowly, sprouts may grow quickly, especially if they arise from well-developed burls . Sapling sprouts usually show rapid growth after top-kill by fire . On the Laguna-Morena Demonstration Area, Cleveland National Forest, Q. dumosa (sl) sprouts that were produced after either burning or clipping had higher rates of photosynthesis and growth than mature plants .
