Types of Fires
NFDRS recognizes four types of fires.
1. Ground Fires burn in natural litter, duff, roots or sometimes high organic soils. Once started they are very difficult to detect and control.
2. Surface Fires burn in grasses and low shrubs (up to 4' tall) or in the lower branches of trees. Surface fires may move rapidly. Ease of control depends upon the fuel involved.
3. Crown Fires burn in the tops of trees. Once started, they are very difficult to control since wind plays an important role in crown fires.
4. Spotting Fires can be produced by crown fires as well as wind and topography conditions. Large burning embers are thrown ahead of the main fire. Once spotting begins, the fire will be very difficult to control.

Famous quotes containing the words types of, types and/or fires:
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
“If you feed a man, and wash his clothes, and borne his children, you and that man are married, that man is yours. If you sweep a house, and tend its fires and fill its stoves, and there is love in you all the years you are doing this, then you and that house are married, that house is yours.”
—Truman Capote (20th century)
