The vegetation on either side of fire boundaries in the alpine zone of Mount Wellington, Tasmania, was
surveyed in 1978 and 1998. This combination of spatial and temporal sampling gave data for 16, 31, 36 and 51 years
since burning. These data were used to test for convergence in vegetation characteristics through time between the
areas burned in 1947 and those burned in 1962 and to determine whether lifeform is a reasonable predictor of the
successional dynamics of species. While convergence largely prevailed, some lifeforms and species diverged and
lifeform was generally a poor predictor of species responses. For example, size class analyses of the larger shrub
species indicated a wide variety of successional responses to fire. The tall shrubs on Mt Wellington have higher
percentages of tolerators and species relying on the soil seed store for postfire regeneration than physiognomically
similar vegetation in more fire-prone environments. Fifty-one years after fire, there is evidence of continuing
floristic and structural change in the alpine vegetation that may be partly related to recent climatic warming
