DescriptionWe counted seedlings and assessed crown characteristics and abundance of fire-induced stump sprout regeneration in California black oak (Quercus kelloggii) 11 to 12 years after wildfire. Regeneration was examined across three levels of burn severity (low, moderate, and high) according to the Composite Burn Index. Fire severity affected crown width of oak sprout clumps; clumps of a given width were taller in areas of high severity fire. Multi-stemmed, sprouting black oak genets were more common than black oak seedlings. The data illustrate a positive sprout clump density association with increasing fire severity. Black oak densities were 3.6, 21.7, and 66.0 genets ac-1 in low, moderate, and high burn severity stands, respectively. Additionally, stand level crown area of the sprouted oak trees was strongly influenced by summed live and fire-killed mature black oak basal area (R2 = 0.83) and density (R2 = 0.73).
