Summary. Low intensity, spring prescribed burns have been used since 1964 at the Cedar Creek Natural History Area in Minnesota in an attempt to restore the area to an oak savanna. Burned areas are now more savanna-like (having greater grass and forb and lower shrub and tree representation) than unburned areas but still have higher overstory densities than apparently existed in presettlement times. No particular burning frequency could be distinguished as best for savanna restoration. Results indicated a possible interaction between fire effects and pretreatment stand structure and composition.
