A climatic gradient across Northwestern Ontario induces a spatial gradient in fire incidence, with few fires in the Northeastern part and many in the Southwestern part. The resultant landscape mosaics exhibit maximum landscape (beta) diversity with intermediate disturbance…

In 1985, Yosemite began using a geographic information system for fire management and research. The system has been used to compare historic fire incidence over a range of topography and vegetation types. Parkwide fuel inventories and prescribed burn units have also been…

The Sanibel-Captiva Conservation Foundation (SCCF) is using high intensity fire to perpetuate fresh-water marsh on Sanibel Island. Shrubs are invading the marsh because of the decreased hydroperiod. A policy of fire conclusion was followed until 1971 when a destructive wildfire…

This study investigates the impact of postulated greenhouse warming on the severity of the forest fire season in Canada. Using CO2 levels that are double those of the present (2 X CO2), simulation results from three general circulation models (Geophysical Fluid Dynamics…

Various studies report changes in phosphorus and nitrogen concentrations in surface waters after wildfires; however, we have found no reports which include nutrient data collected during actual wildfire activity. We had an opportunity to collect water chemistry data from several…

The effects of a late-summer prescribed burn on the chemistry of a second-order mountain stream in the south-western Cape, South Africa, were investigated. Nitrate concentrations in stream water were significantly higher during the winter of the post-burn year. Increased…

Climate, vegetation, and fire are interrelated so that any change in one will affect the others. Increases in greenhouse gases, especially carbon dioxide, are expected to increase average surface temperatures and alter precipitation patterns. These changes will alter numerous…
