Forest Fires in Northern Canada, with an Introduction by Martin E. Alexander

Author: Robert Bell
Pages: 1-10
DOI: 10.4996/fireecology.0801001

I consider Dr. Robert Bell (1841-1917) to be the father of boreal forest fire ecology and fire behaviour in Canada. It is thus a very great honor to have been asked to recommend the article that follows and then have the privilege to write this introduction to it.

I first began to learn of Dr. Bell’s writings back in 1976 soon after I was hired on as a forest fire research officer with the Canadian Forestry Service at the Great Lakes Forest Research Centre in Sault Ste. Marie, Ontario. I had intended someday to write an article about Dr. Bell and his observations regarding forest fires in the northern regions of Canada, considered “so astute that most can still stand today, more or less unrevised” (Pyne 2007). Instead, I turned my Bell collec­tion over to Dr. Steve Pyne in February 2002 with the hope that he could make good use of the materials as he undertook to chronicle the cultural history of forest fires in Canada, which he admirably did in a section of his book, Awful Splendour: A Fire History of Canada (Pyne 2007: 146-154, 494-495).

Factors Associated with the Severity of Intersecting Fires in Yosemite National Park, California, USA

Authors: Jan W. van Wagtendonk, Kent A. van Wagtendonk, and Andrea E. Thode
Pages: 11-31
DOI: 10.4996/fireecology.0801011

In 1972, Yosemite National Park established a wilderness fire zone in which lightning fires were allowed to run their courses under prescribed conditions.  This zone was expanded in 1973 to include the 16 209 ha Illilouette Creek basin, just to the southeast of Yosemite Valley.  From 1973 through 2011, there have been 157 fires in the basin.

Shrub Seed Banks in Mixed Conifer Forests of Northern California and the Role of Fire in Regulating Abundance

Authors: Eric E. Knapp, C. Phillip Weatherspoon, and Carl N. Skinner
Pages: 32-48
DOI: 10.4996/fireecology.0801032

Understory shrubs play important ecological roles in forests of the western US, but they can also impede early tree growth and lead to fire hazard concerns when very dense.  Some of the more common genera (Ceanothus, Arctostaphylos, and Prunus) persist for long periods in the seed bank, even in areas where plants have been shaded out.  To determine shrub seed density and investigate the feasibility of managing shrub abundance by regulating the size of the soil seed bank with fire, we sampled the seed bank in 24 mixed conifer forest stands throughout northern California.

Age and Structure of Mature Knobcone Pine Forests in the Northern California Coast Range, USA

Authors: Danny L. Fry, James Dawson, and Scott L. Stephens
Pages: 49-62
DOI: 10.4996/fireecology.0801049

An understanding of current structural conditions and disturbance history is a requisite for optimal management of forest ecosystems, especially for serotinous species such as knobcone pine (Pinus attenuata Lemmon).  Knobcone pine is widely distributed in California, yet little is known regarding age and forest structure patterns.  In this study, we quantify forest conditions of 21 mature knobcone pine stands in the northern Mayacmas Mountains, north Coast Range, California, USA.

Crawfish Frog Behavioral Differences in Postburned and Vegetated Grasslands

Authors: Nathan J. Engbrecht and Michael J. Lannoo
Pages: 63-76
DOI: 10.4996/fireecology.0801063

Amphibians are threatened globally and, with the increased emphasis on using prescribed fire as an important tool to manage ecosystems, it is essential to understand how amphibians respond when exposed to habitats managed by fire.  Most studies have focused on survivorship and population-level effects; how survivors react to postburn landscapes has received less attention.

Modelling Fire Ignition Probability from Satellite Estimates of Live Fuel Moisture Content

Authors: Sara Jurdao, Emilio Chuvieco, and Jorge M. Arevalillo
Pages: 77-97
DOI: 10.4996/fireecology.0801077

Biomass burning has critical ecological and social impacts.  Recent changes in climate patterns and land use have involved alterations of traditional fire regimes, which have increased the negative impacts of fire.  Live Fuel Moisture Content (LFMC) has proven to be one of the main factors related to fire risk, as it affects fire ignition and fire behavior, and therefore it is an essential indicator for fire risk assessment.

Wildfire Consumption and Interannual Impacts by Land Cover in Alaskan Boreal Forest

Authors: Crystal A. Kolden and John T. Abatzoglou
Pages: 98-114
DOI: 10.4996/fireecology.0801098

Boreal forest fires are an important source of terrestrial carbon emissions, particularly during years of widespread wildfires.  Most carbon emission models parameterize wildfire impacts and carbon flux to area burned by fires, therein making the assumption that fires consume a spatiotemporally homogeneous landscape composed of predominantly spruce forests and peat bogs with deep duff layers.
