Paired charcoal and tree-ring records of high-frequency Holocene fire from two New Mexico bog sites
This article aims to reconstruct historical fire histories and fire-climate relationships extending back approximately 15,000 years by sampling from charcoal cores in medium-elevation bog sites.
Charcoal concentration in the sediment records at both bogs varied considerably over 15,000 years suggesting that climate affected both vegetation and fire regimes. Around approximately 8,000 years before present, sharp increases in charcoal concentrations indicate increased warming, however, the authors were unable to interpret the fire history due to confounding factors, specifically the low sedimentation rate during these periods. Still, at the both bog sites, a departure in superposed epoch analysis PDSI of -2, indicating very dry conditions, coincided with widespread fire years between the 1500’s and early 1900’s.
