FIRE HISTORY
type: Concept
change note: 2012-07-23 16:39:58.0 [mpmorahan] insert Definition (id: null text: Fire history information is provided through two types of proxy data; tree-ring based records and sediment based records. These data sources describe fire regimes at multiple temporal and spatial scales. Tree-ring data provide temporally precise, short-term reconstructions of fire events, usually spanning the last 400 years or less. By carefully crossdating and examining the tree rings, the exact year and often even the season in which the fire occurred can be determined. These data offer a high level of spatial resolution in a fire reconstruction in that the location of fire-scarred trees identifies the exact location of particular fires. Although tree-ring methods extend back to the age of the oldest living tree, the records attenuate back through time as older trees are less abundant. language code: en);
