Fire-dependency of germination varies within a species even between nearby populations.

Evidence

In Adenostoma, however, a portion of any year’s seed crop will germinate after a brief after-ripening, whereas the remainder requires heat treatment (Stone and Juhren, 1952). Jones and Schlesinger (1980) found that seeds of Emmenanthe penduliflora, an annual herb, collected from recently burned chaparral sites required a char treatment to effect germination. Emmenanthe penduliflora seeds collected from desert sites where fires are uncommon did not. — S. T. A. Pickett and P. S. White, eds., The Ecology of Natural Disturbance and…, 641
