Blazes That Damaged Yellowstone Changed Wildfire Strategy

A rapidly growing California wildfire is threatening a grove of giant Sequoia trees in Yosemite National Park, some nearly 3,000 years old. For context, we examine the 1988 fires in Yellowstone National Park that ignited a debate over firefighting tactics and sustainable forestry.

Increasingly, wildfires affect populated areas. But more than 30 years ago, it was a huge fire in Yellowstone National Park that stoked media attention and political controversy.

The continuing narrative that summer was that park officials had negligently let the fires burn out of control and destroyed the legendary national park, which had supplied generations of visitors with fond memories and colorful snapshots.

But the story that played out on national television was incomplete. Until the 1970s, fire policy had called for putting out every forest fire as soon as it started, creating tons of underbrush in Yellowstone – and in parks across the nation. And that underbrush had set the stage for raging wildfires. When federal officials shifted fire policy in 1972 to allow for naturally-caused fires to burn themselves out, and, hopefully, reduce potentially deadly build up of underbrush, it turned out to be too little too late. It failed to make a dent in the thousands of acres of dry underbrush that ignited in Yellowstone during the summer of 1988, the summer that gave everyone an education in fire.

For Educators

Introduction

This 10-minute video explores the lessons from the Yellowstone fires of 1988 that gave rise to a national political controversy about the relationship between fires and sustainable forestry. The video shows students how public attitudes towards fire and forestry had been molded for decades toward preventing and fighting forest fires, and how the Yellowstone fires led to a reevaluation of these ideas. Useful as an introduction to the context and complexities of forestry policy, the video helps students see recent debates over wildfires within a larger historical framework.

Background reading

In 1988, wildfires burned out of control in Yellowstone National Park and virtually destroyed a national landmark.

That, at least, was a message broadcast by the national news media. But the reality proved more complex.

The wildfires did burn nearly a third of the park, but it wasn’t destroyed, nor were park officials to blame.

For decades, federal park policy put out every fire as soon as it started, a message driven home since the 1950s by advertisements featuring Smokey Bear.

But that policy allowed underbrush to quietly build up across the country’s national parks, providing dangerous fuel for potential wildfires.

To reduce that threat, park officials in 1972 began to let natural fires burn out unless computer models predicted a threat to life or property.

By the summer of 1988 in Yellowstone, that “natural burn” policy had failed to reduce the underbrush. Worse, a severe drought had turned the dead leaves and fallen limbs into tinder, ready to burn.

That summer, rare fierce winds ravaged the park, so when lightning ignited a series of small fires, they quickly spread, and soon rendered all existing fire-control models obsolete.

For two months, an army of firefighters fought daily to contain the spreading wildfires, but they were only put out with the help of a snowstorm in September.

The real lesson of 1988 was that naturally-caused fires are necessary to control the buildup of underbrush, and reduce the threat of devastating wildfires. But letting the fires burn isn’t always an option near some developed areas.

Lesson Plan 1: The Yellowstone Fires of 1988
Overview

Students will learn how the Yellowstone fires of 1988 created a national controversy that challenged long-held assumptions about the role that fires should play in forestry policy.

Objectives

Students will:

  • Explain how the news media can affect public policy changes in environmental policy.
  • Examine how the federal government’s policy toward the role of fires in forestry management has changed since 1910.
  • Explain how fires affect forest ecosystems.
  • Compare the strategies of Native Americans who used fire with modern forest management.
Essential questions
  • How did the 1988 Yellowstone wildfires affect public attitudes toward fire and forestry?
  • How did the federal government’s policy toward the role of fires in forestry management change since 1910?
  • What lessons have been learned from indigenous cultures about fire management?
  • How will climate change affect the frequency and severity of forest fires?
