Vegetation undergoes a natural succession after wildfire. Following an initial flush of vegetation, when light and other resources become limiting, the stand structure rapidly reaches a maximum. As a result, vegetation structure does not form an even distribution over the landscape, but rather a patchwork pattern. The position and characteristics of a patch of habitat in the landscape may be critical in determining the faunal composition. In this paper a sequence of 'habitat complexity scores' (which describe vegetation structure independently of plant species) collected over 20 years following a wildfire was utilised to estimate vegetation structure in relation to time since fire. This information was compared with data collected over the same period on medium-sized and large ground-dwelling mammals to examine the response of mammals to changes in vegetation structure. Models are presented of the response of ground-dwelling mammals to time since wildfire and to changes in habitat complexity scores, with predictions up to 25 years after wildfire.
