Abstract

Fire has become a common problem for all of us. It is not a friend of anyone. Fire has different types and modes. It is dangerous for those who live beside it. Nearly a century of fire repression means that many ecosystems suffer an overabundance of flammable fuel. When a lightning bolt or camper's match ignite a fire during a dry spell, the result is catastrophic. Fires burn hotter and bigger than they would in frequently burned environments. The legacy of suppression may be a key factor in the large number of catastrophic wildfires burning the forests of America, southeast Australia, and Mediterranean Europe over the past two decades. In turn, footage of raging flames and charred buildings from these events spurns continued political pressure to stop all fires. Prescribed or controlled burning plays a key role in current fire policy. Fire is a difficult and expensive tool to master.

Introduction

The mastery of fire separates humans from other animals. Our use of this chemical reaction— on landscapes, in hearths, and in industry—is one of our most fundamental and influences on the environment. Without fire, many of our foods and landscapes would be unrecognizable. But fire also destroys homes and habitats, and inspires or even expresses conflict between different people. (Barker, 2005, 61-75)

Fire is a chemical chain reaction akin to photosynthesis in reverse. Once sufficiently heated, fuels react with oxygen in the air to produce carbon dioxide, water vapor, and heat energy. The size, type, and moisture content of fuels, as well as the prevailing weather conditions (humidity, precipitation, temperature, and wind), are crucial in affecting the threshold for ignition and potential for spread. The most common fuels for fire are biomass like trees or grasses, and fossil biomass like coal or oil. Fires are more frequent in landscapes with both wet and dry periods, like seasonal tropics or Mediterranean climates. Biomass accumulates during wet seasons and then dries out. Deserts are typically too dry for combustible biomass to accumulate; humid temperate, boreal, and humid tropical regions only occasionally dry out sufficiently to allow fires to propagate.

Background

Historically, forest fires have been left to burn uncontrolled for weeks at a time. They were caused by different things such as lightning or hunters who wanted to chase animals out of the woods. These fires had catastrophic effects on humans and the environment through history. Homes built among wild brush are perfect prey to wildfires. A forest fire can destroy hundreds of homes in a matter of weeks. These fires have profoundly affected the environment (Pyne, Andrews and Laven, 1996, 36-47). They have done damage to the vegetation as well as the inhabitants. Traveling through wildfire areas, it is almost impossible to imagine that the beautiful environment could foster such a deadly fire. Now, grid technology has much more contributed in fire safety measures.

A forest fire is a terrifying sight. Flames and sparks leap from tree to tree igniting almost anything that they ...
