 Fire
and Vegetation Dynamics : Studies from the North American Boreal
Forest (Cambridge Studies in Ecology) by
Edward A. Johnson.
It is almost dogma that the boreal
forest in North America is a fire dependent forest, yet
ecologists often do not consider in any technical detail how
forest fires produce effects on individual plants and on plant
populations; Consequently, the causal connection between the
behavior of fire and its ecological consequences is poorly
understood. This book sets out to correct this deficiency by
assembling the relevant studies of fire intensity, rate of
spread, fuel consumption, fire frequency and fire weather in the
North American boreal forest. The central thesis is that the
North American boreal forest has at least four wildfire
characteristics that are important in understanding the dynamics
of its plant populations: the large size of the burns with
respect to dispersal distances, the short recurrence time of
fire with respect to tree life spans, the high mortality of
plants due to the predominance of crown forest and a good
germination surface due to the large area of the forest floor
which is covered by ash.

Essay by George Wuerthner. Excerpt:
No single human modification of the environment has had more pervasive and widespread
negative consequences for the ecological integrity of North America than the suppression
of fire. Fire suppression has destroyed the natural balance of the land more than
overgrazing, logging, or the elimination of predators. One could easily build a case that
an Environmental Impact Statement should be prepared prior to any fire suppression
activities by government agencies since control of wildfires greatly alters the natural
environment. Yet, most people are oblivious to the many long-term consequences of fire
suppression policies...

By the Congressional Research Service (Ross Gorte). Summary:
Interest in fuel management, to reduce fire control costs and damages, has been renewed
with the numerous, destructive wildfires spread across the West during the summer of 1994.
Fuel management is often linked to forest health, since major forest health concerns
include excess biomass (i.e., fuel loadings) and catastrophic fires. Several tools,
such as prescribed burning and salvage timber sales, can address these problems, but the
extent of the problem and the cost of needed treatments are genera lly unknown. Fuel
management may well reduce fire control costs and damages, but the evidence is largely
anecdotal, with few documented estimates of the decline in control costs and/or damages
associated with fuel treatments. Finally, the roles and responsibilities of the Federal
and State governments in fire protection may be subject to further debate.

This server has been developed to support operations of
Central Aviation Base of Russian Forest Defense Service. Server provides daily information
about fire risk and fire status of forests. You can view sample information, similar to that
provided for registered users. Server is developed and maintained in collaboration by
Central Aviation Base of Russian Forest Defense Service (Pushkino, Moscow region),
International Forestry Institute (Moscow), Institute of Solar-Terrestrial Physics SO RAN
(Irkutsk), and Space Monitoring Information Support
laboratory of Space Research Institute (IKI) RAN
(Moscow).

The Canadian Interagency Forest Fire Center (CIFFC) provides
operational fire-control services, as well as management and information services to its
Member Agencies. In addition to coordinating services for all of the provinces and
territories, CIFFC often coordinates the sharing of resources with the United States and
other countries.

Forest fire lookouts have captured the imaginations of people
for years. They have been the settings for books, television shows and movies. In the past
30 years, numerous lookouts have been shut down in favor of inefficient aerial patrols and
vague reports from residents. Still, some towers continue to be staffed every summer, some
by volunteers, others by fully paid personnel.
