A stand replacing crown fire was set in 1983 for the purpose of increasing the quality and quantity of a bighorn sheep range on Ram Mountain, Alberta. The area burned was a 250-year-old white spruce (Picea glauca [Moench] Voss) stand in close proximity to escape terrain and bighorn winter range. When postburn feild data, which were obtained during the 1983 through 1986 and 1992 field seasons, are compared to the preburn data, results show that most plant species survived the effects of the fire or were able to re-colonize after it. Sorensen's Index of Similarity went from 51%, one month after the fire, to over 70% by 1992. Tree and shrub cover has not returned to preburn levels, while grass has doubled and forb cover has increased over 400%. Sheep use has significantly increased.
