). Climate plays a role since intense droughts induce vegetation die-
back, thus increasing dead fuels, as well as reducing live fuel moisture, both of
which will increase fire intensity and reduce resprouting. Shorter fire intervals, and
fires at certain seasons, potentially deplete carbohydrate reserves and this is tied to
reduced resprouting (Rundel
