Abstract Detail


The Cross Timbers: Botany, History, and Current Issues

Shirakura, Fumiko [1], Palmer, Michael W. [1].

Fire history of a Crosstimbers Forest in the Tallgrass Prairie Preserve, Osage County, Oklahoma.

The Tallgrass Prairie Preserve (TGPP) managed by the Nature Conservancy (TNC) is located in northeastern Oklahoma. It mainly consists of tallgrass prairie with scattered crosstimbers forests. The TNC has managed it using randomized fire since 1990. No information is available for the occurrence of fires, natural or man-caused, prior to 1990. An opportunity for examining fire history arose in 2003, when clearing the damage caused by a tornado resulted in the uprooting of numerous trees in a crosstimbers forest at the edge of the TGPP. In June 2004, we removed basal disks from 88 dead Quercus marilandica and 60 Q. stellata. We obtained 33 fire-scarred tree disks and processed, aged, measured ring width and dated fire events based on dendrochronology. We used COFECHA, the computer software to check accuracy of dating and quality of measurement accuracy of tree rings. We discuss our results in light of the current fire management of the TGPP.
