Table 2 Fire interval statistics for four different spatial scales in the Giant Forest, Sequoia National Park. All intervals were computed for the period 200 to 1700 C.E., except for the CME group scale, which was computed for the period 500 to 1700 C.E. Statistics were computed for fire intervals based on all fire indicators, all fire indicators recorded on two or more trees, fire scars only, and fire scars only and recorded on two or more trees. An additional composite category of all fire indicators as recorded on 25% or more of recording trees was also computed for the grove level of analysis.
