简介
- 1Studies on the variability of natural fire regimes are needed to understand plant responses in a changing environment. Since vegetation changes might follow or trigger changes in fire frequency, climate models suggest that changes in water balance will accompany current global warming, and the response of fire regimes to Holocene hydro‐climate changes and vegetation switches may thus serve as a useful analogue for current change.
- 2We present high‐resolution charcoal records from laminated cores from three small kettle lakes located in mixed‐boreal and coniferous‐boreal forest. Comparison with some pollen diagrams from the lakes is used to evaluate the role of the local vegetation in the fire history. Fire frequency was reconstructed by measuring the separation of peaks after detrending the charcoal accumulation rate from any background.
- 3Several distinct periods of fire regime were detected with …
