Causal factors and consequences of mixed-severity fire in Black Hills ponderosa pine forests
We used the ~ 34,000 ha Jasper fire of 2000 to address the theme of mixed- severity fire in Black Hills ponderosa pine forests. Mixed severity fire resulted in many patches of low, moderate, and high severity, distributed in roughly equal proportion across the burned landscape. There was a …

Fire History of an Acidic Barrens Complex: A Methods Assessment of Fire Return Intervals
Fire-scarred trees provide an important source of data and direct evidence for understanding past fires and vegetation dynamics. Although dendrochronological fire scar records provide fine-scale temporal and spatial resolution, limitations exist in the development, analysis, and interpretation of …

Drivers and Impacts of Smoldering Peat Fires in the Great Dismal Swamp
… notably including high intensity, soil-consuming fires. Peat soil fires are unique in that they can smolder vertically through the soil column, with consequences ranging from large carbon emissions to altered hydrology and dramatic shifts in vegetation communities. In this work we had two …

Comparison of Charcoal and Tree-Ring Records of Recent Fires in The Northern Rocky Mountains, Kalispell, MT, USA
… In this study we created a dendrochronological fire history using fire-scarred trees in the watershed of Foy Lake in the Flathead Valley, MT, to determine the synchronicity between two fire proxies: the watershed’s tree fire scar chronology and the dated charcoal in the sediment lake strata. I …

Identifying the effects of land use and policy on disturbance regimes in the Teanaway Community Forest, Washington
The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to …

A Tree Ring Based Fire History of the Clover Mountains, Lincoln County, Nevada
Fire is a dominant form of disturbance in the American west, and is a primary management concern because of its threat to natural resources and human development. Research on fire history of the Great Basin is lacking. Here I summarize the results of a fire history study in the Clover Mountains of …

Spatial and temporal patterns (1973-2012) of bushfire in an arid to semi-arid region of Western Australia
… The aim of this study was to reconstruct fire regimes/history of an extensive arid to semi-arid region of Western Australia for the last 40 years by studying temporal and spatial fire scar patterns using remote sensing in a Geographic Information System environment. Methods A fire history …

The modeled effects of fire on carbon balance and vegetation abundance in Alaskan tundra
… shrubland expansion, and increases in fire frequency. Whether tundra remains a global net sink of carbon could depend upon the effects of fire on vegetation, specifically concerning the speed at which vegetation reestablishes, the stimulation of growth after fire, and the changes that …
