Abstract

Many conservation areas are effectively islands in a sea of agricultural or urban development in which natural disturbance regimes have been altered or limited. Managers of such areas often need to artificially maintain disturbance regimes in order to control ecosystem processes such as vegetation succession (Richards ef al. 1999). The relationship between disturbance, succession, vegetation change and habitat heterogeneity is crucial to managers because together they can influence biodiversity. For example, a break in the disturbance regime could promote woody plant encroachment. Though this might lead to an increase in habitat heterogeneity, the effects on biodiversity could be positive or negative. Habitat heterogeneity, in this context, can refer to vegetation variability or complexity at a range of spatial scales.
