Firefighters Battle Blazes with New Tools ; Computers and Satellites Help to Detect and Monitor Fires during a Bad Wildfire Season


Brad Knickerbocker writer of The Christian Science Monitor, The Christian Science Monitor


Water-logged easterners may not believe it, but much of the country is unseasonably dry.

Moisture levels are below average in Colorado, Arizona, New Mexico, Montana, and Wyoming, and much of the Great Plains from Oklahoma to North Dakota is experiencing drought as well. In all, one-fourth of the US is facing moderate-to-extreme drought conditions, which brings the threat of fire.

"The long-term moisture deficits and high fuel loadings are producing critically high fire potential, particularly in the higher elevation timber," researchers at the University of Arizona's Institute for the Study of Planet Earth reported recently.

As a result, the number of fires and the acreage burned have set 10-year highs. The number of acres burned so far is more than twice the average over the past decade, according to the National Inter- agency Fire Center in Boise, Idaho. One 40,000-acre fire even threatened the University of Nevada Fire Science Academy, giving students the kind of on-the-job training they hadn't counted on.

Wildfire detection and management have gone through a renaissance of sorts in recent years, experts say. Rotating digital cameras are replacing human lookouts posted in lonely mountain towers. Satellites, computers, remote automated weather stations, and lightning strike detectors are among the new tools used to monitor, map, and model fires.

"It's really giving people more comfort in their ability to predict fire behavior," says veteran firefighter Timothy Ingalsbee, executive director of Firefighters United for Safety, Ethics and Ecology (FUSEE) in Eugene, Ore. This year's high fire danger was predictable as well, he says. A wet season allowing lots of surface vegetation to grow has been followed by an unusually dry season where all that vegetation is available to burn.

With more people moving into what's called the "wildland-urban interface," coordinating fire-fighting efforts among agencies becomes more complicated and contentious.

The recent political focus on immigration is an issue since many Hispanics are contract firefighters. No one knows how many people are in the US illegally, and cracking down on illegal immigrants, as well as the deployment of National Guard troops overseas, has governors in fire-prone states concerned that they may not have sufficient resources to fight fires this summer.

Postfire salvage logging is a concern, too. Proponents say such logging, followed by replanting, helps reduce the risk of future fires and allows for quicker regeneration. But many wildland firefighters disagree.

"Timber plantations thick with even-aged nursery-grown conifers, untreated logging slash, and invasive weeds pose some of the greatest hazards to firefighters," members of FUSEE wrote in a letter to Congress this spring.

"Wildfires are prone to sudden 'blow-ups' when they enter this volatile mix of hazardous fuel," warned this group, whose members include current and retired wildland firefighters. …
