Quantitative comparison of an oak savannah with a post oak-blackjack forest indicates that the forest was a savannah before about 1890. The savannah and the forest have similar numbers of trees larger than 12.5 cm DBH, while the forest has many more small stems than the savannah. Due to the different nature of the litter in the two stands, a fire kills most of the small woody vegetation in the savannah, while leaving the small woody vegetation in the forest relatively undamaged. The recent conversion of most central Oklahoma savannahs to forests is probably due to the reduction in frequency and intensity of fires.
