Historical Range of Variability Revisited
... Historical ecological studies document how changes in land use, such as grazing influences on fuels or elimination of fires set by aboriginal populations, have affected fire regimes of particular ecosystem types in the past (Gruell 1985, Savage and Swetnam 1990). Likewise, retrospective studies have ...
