A panoramic picture of fires in ponderosa pine ecosystems

Individual fire history studies paint a picture of how often and how severely fires burned on specific landscapes, providing valuable points of evidence for land management decisions. Syntheses of multiple fire history studies weave these individual pictures into a panoramic tapestry, providing a more complete understanding of historical fire regimes. For example, syntheses of fire history studies in ponderosa pine communities tell stories about precolonial historical fires frequently burning small areas and occasionally burning large areas, followed by a century with very few fires due to fire exclusion. Fire exclusion began with European settlement, first by reducing ignitions by American Indians, then by reducing fine-fuel biomass and connectivity with livestock grazing and eventually, through active fire suppression.
