The course of a post-fire succession was inferred in the subalpine zone (3300-4000 m) on Mt. Wilhelm. The availability of a detailed pollen history and 20-yr-old photographs from the study area enabled the rate of the succession to be estimated. Anthropogenic fires cause the replacement of forest by grassland. In the absence of fire significant changes occur within 20 yr and secondary forest can develop on favourable sites in less than 300 yr. Succession proceeds by the diffuse invasion of the grassland rather than by a general advance of the forest margin. Succession is much slower on east-facing than on west-facing slopes.
