Passage: The worst loss of life in United States history due to a wildfire occurred in 1871 when the Peshtigo Fire swept through Wisconsin, killing more than 1,500 people. The Santiago Canyon Fire of 1889 in California and especially the Great Fire of 1910 in Montana and Idaho contributed to the philosophy that fire was a danger that needed to be suppressed. The Great Fire of 1910 burned 3,000,000 acres (12,000 km2), destroyed a number of communities, and killed 86 people; this event prompted various land management agencies to emphasize wildfire suppression. U.S. Government land agencies, including the National Park Service, generally followed the fire management policies established by the U.S. Forest Service, which oversees the majority of the nation's forestlands.

Question: What is the responsibility of U.S. Forest Service?
