We have compared fire history and forest dynamics in the East versus West Kootenay areas of southeastern British Columbia. In both areas, fire regimes varied significantly with steep elevational gradients. At high elevations, stand-replacing fires burned every 150-300 years according to our fire scar, forest age structure and lake sediment records. In the lower-elevation forests, low-severity fire ...

Wildfires in the boreal forests of Siberia may significantly contribute to global warming through feedbacks related to greenhouse gas emissions. How future warming will affect boreal fire regimes remains uncertain due to a lack of knowledge on the climatic controls of fire. Here we present fire-climate relationships derived from a new set of tree-ring reconstructions of fire history for the Sakha ... More

Fire is a major disturbance agent in North American forests. Fires injure trees when heat transfer through the bark partially kills the cambium and the compartmentalization process results in a fire scar. Dendrochronologists use these scars in the xylem to reconstruct fire regimes. However, little information exists on the wood anatomy of fire scars. Consequently, this study quantifies changes in ...

In Mongolia, mean annual temperature has increased by 2OC and forest and steppe fires have increased in temporal and spatial scales in recent decades. We developed a network of fire-scar chronologies across forests in northern Mongolia to place this recent fire history and associated fire climatology into their longer term historical context, and to assess relationships between historical fires an ...

Forest fires are one of the main disturbance agents in boreal and temperate ecosystems. To decipher large-scale temporal and spatial patterns of past fire activity in Scandinavia, we analyzed the synchronicity of dendrochoronologically reconstructed fire events in a large network of sites covering a wide geographical gradient (56.5 - 67.0 º N and 9.3 - 20.5 º E) over AD 1400-1900. We identified ... More

Potential impact of climate change on timber supply was evaluated considering the role of climate on forest growth and fire activity in a forest management unit in the boreal zone of eastern Canada. A climate sensitive growth index model was calibrated for three commercial species. Such a model was used to project the evolution of merchantable volume over time under sustained yield timber producti ... More
