Interactions among Prescribed Fire, Soil Attributes, and Mycorrhizal Community Structure at Crater Lake National Park, Oregon, USA
Pages: 30-50
DOI: 10.4996/fireecology.0502030

We identified relationships between prescribed burn treatments and selected soil and fuel attributes on mycorrhizal fungus fruiting patterns in an old-growth ponderosa pine (Pinus ponderosa) and white fir (Abies concolor) stand in Crater Lake National Park, Oregon, USA. Three prescribed burn treatments (early spring, late spring, and fall burns) plus non-burned controls were applied to 24 ~3 ha units in 2002. We sampled mycorrhizal fungus sporocarp production in the spring and fall in the ensuing three years, and collected data on surface fuels, soil C and N concentrations, δ13C and δ15N signatures, pH, and mineral soil bulk density. A gradient of C:N ratios and other soil attributes across the study area facilitated separation of the effect of fire from the effects of soil attributes on fungal fruiting patterns.  [Read More]

Burning at the Edge: Integrating Biophysical and Eco-Cultural Fire Processes in Canada’s Parks and Protected Areas
Pages: 74-106
DOI: 10.4996/fireecology.0701074

Currently, high intensity, large-area lightning fires that burn during droughts dominate Canada’s fire regimes. However, studies from several disciplines clearly show that humans historically ignited burns within this matrix of large fires. Two approaches for fire research and management have arisen from this pattern: a “large-fire biophysical paradigm” related to lightning-ignited fires, and an “eco-cultural paradigm” related to human-caused burning. Working at the edge between biophysically driven fires and eco-cultural burns, and their associated management and research paradigms, presents unique challenges to land managers.  [Read More]

Modeling Wildfire Spread in Mountain Pine Beetle-Affected Forest Stands, British Columbia, Canada
Pages: 10-35
DOI: 10.4996/fireecology.1002010

The mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) has killed lodgepole pines (Pinus contorta Dougl. ex Loud.) across 20 million hectares of central British Columbia, Canada, since the late 1990s, challenging land managers as well as fire management personnel. Although recent studies have used models to simulate how MPB might affect fire spread, very little fire behaviour has been documented in MPB-affected stands.  [Read More]
