Wild or Prescribed: Two Kinds of Fire

The story of fire can be confusing. You are asked to prevent wildfires, yet park personnel set prescribed fires. Fires are given different labels, depending on whether or not they are wanted.

Wildfires are unwanted lightning- or human-caused fires. They are suppressed because they threaten lives, property, survival of the forest, or because they are too difficult to manage when and where they start. Fire suppression is a tremendous risk to firefighters, and consumes millions of tax dollars. The Kaweah Fire in August 1996 was started by a car's exhaust pipe in dry grass on a road shoulder. It burned 4,479 acres, risked the safety of over 1,500 fire fighters, and cost $4 million.

On the other hand, fire does contribute to forest health and public safety. Prescribed fire, whether started by nature or planned by people, is a carefully managed tool to achieve such goals. A fire's "prescription" includes detailed analyses of geographic and ecological conditions. A prescription is the window within which a fire may be ignited. These conditions maximize our ability to control the fire and to minimize smoke in local communities. If the weather doesn't meet the prescription, the fire is not ignited.

Why use a tool that appears to be as destructive as fire? Burning around buildings clears grass and other flammable material that would feed destructive fires. Other fires play important ecological roles. Lightning fires have burned frequently here for centuries. Some plant species, including giant sequoias, reproduce better after fire. An ash seedbed is critical to germination and growth of sequoia seedlings. Fire also opens the forest canopy, allowing sunlight to reach the seedlings. Historically, fires have burned in sequoia groves roughly every 5 to 15 years. In the past century, our suppression of fire has blocked this important process. Vast accumulations of deadwood increase wildfire hazards dramatically, and sequoias do not reproduce. Animal species also benefit as increased acorn production, abundant berries and herbaceous plants that come in after a fire provide increased forage for wildlife.

To reduce hazards and restore natural conditions, trained crews carefully plan the size and timing of fires. For the same reasons, lightning fires that are in prescription and away from buildings are not suppressed.

Trails around prescribed fires sometimes remain open, so please use caution. Ask rangers for information, and enjoy the chance to see a powerful natural tool in managing park resources.

Did You Know?

Beautiful white spar crystals.

Sequoia and Kings Canyon National Parks could have been set aside solely to protect the amazing caves found here. The parks protect half of the caves more than a mile long in California, including the longest cave in the state. They contain Pleistocene-era fossils, rare minerals and unique animals.
